Operation Guide 5497
Congratulations upon your selection of this CASIO watch.
Applications The built-in sensors of this watch measure direction, barometric
pressure, temperature and altitude. Measured values are then shown on the
display. Such features make this watch useful when hiking, mountain climbing,
or when engaging in other such outdoor activities.
Warning ! · The measurement functions built into this watch are not intended
for taking measurements that
require professional or industrial precision. Values produced by this watch
should be considered as reasonable representations only. · When engaging in
mountain climbing or other activities in which losing your way can create a
dangerous or life-threatening situation, always use a second compass to
confirm direction readings. · Note that CASIO COMPUTER CO., LTD. assumes no
responsibility for any damage or loss suffered by you or any third party
arising through the use of your watch or its malfunction.
ENGLISH
Important! · The watch’s Altimeter Mode calculates and displays relative
altitude based on barometric pressure
readings produced by its pressure sensor. This means that readings taken at
different times at the same location may produce different altitude values due
to changes in barometric pressure. Also note that the value displayed by the
watch may be different from the actual elevation and/or sea level elevation
indicated for the area where you are located. · When using the watch’s
altimeter while mountain climbing, be sure to perform regular calibration in
accordance with the local altitude (elevation) indications. For more
information, see “To specify a reference altitude value” (page E-46). ·
Whenever you use the digital compass of this watch for serious trekking,
mountain climbing, or other activities, be sure always to take along another
compass to confirm readings. If the readings produced by the digital compass
of this watch are different from those of the other compass, perform
bidirectional calibration of the digital compass to ensure more accurate
readings. · Direction readings and digital compass calibration will not be
possible if the watch is in the vicinity of a permanent magnet (magnetic
accessory, etc.), metal objects, high-voltage wires, aerial wires, or
electrical household appliances (TV, computer, cellphone, etc.)

Charging the Watch
The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.
Charging Guide
Whenever you are not wearing the watch, leave it in a location where it is
exposed to light. · Best charging performance is
achieved by exposing the watch to the strongest light available.
When wearing the watch, make sure that its face is not blocked from light by
the sleeve of your clothing. · The watch may enter a sleep state
(page E-18) if its face is blocked by your sleeve even only partially.
Warning! Leaving the watch in bright light for charging can cause it to become
quite hot. Take care when handling the watch to avoid burn injury. The watch
can become particularly hot when exposed to the following conditions for long
periods. · On the dashboard of a car parked in direct sunlight · Too close to
an incandescent lamp · Under direct sunlight
E-12
E-11
Important!
· Allowing the watch to become very hot can cause its liquid crystal display
to go blank (totally black or totally white, depending on the watch model).
The appearance of the LCD should become normal again when the watch returns to
a lower temperature.
· Turn on the watch’s Power Saving function (page E-18) and keep it in an area
normally exposed to bright light when storing it for long periods. This helps
to ensure that power does not run down.
· Storing the watch for long periods in an area where there is no light or
wearing it in such a way that it is blocked from exposure to light can cause
power to run down. Expose the watch to bright light whenever possible.
Power Levels
Hold down B for at least two seconds to enter the Timekeeping Mode. You can
get an idea of the watch’s power level by observing the battery power
indicator on the display.

· The flashing L indicator at Level 3 (L) tells you that battery power is very
low, and that exposure to bright light for charging is required as soon as
possible.
· Once the battery reaches Level 2 (M) after falling to Level 5, reconfigure
the current time, date, and other settings.
· Display indicators reappear as soon as the battery is charged from Level 5
to Level 2 (M).
E-14
· Leaving the watch exposed to direct sunlight or some other very strong light
source can cause the battery power indicator to show a reading temporarily
that is higher than the actual battery level. The correct battery level should
be indicated after a few minutes.
· All data stored in memory is deleted, and the current time and all other
settings return to their initial factory defaults whenever battery power drops
to Level 5 and when you have the battery replaced. A dark environment while
battery power is at Level 4 will cause the level to drop to Level 5. Expose
the watch to bright light whenever possible.
· The Home City setting reverts to the initial default of TYO (Tokyo) whenever
the battery power level drops to Level 5 or when you have the rechargeable
battery replaced. If this happens, change the Home City to the setting you
want (page E-24).
Jumps at two-second intervals
Low battery alert
When battery power reaches Level 3, the second hand of the watch will jump at
2-second intervals in the Timekeeping Mode to let you know that charging is
required.

Power Recovery Mode
· Performing multiple sensor, illumination, or beeper operations during a
short period may cause the recovery indicator (RECOVER) to start flashing on
the display. This indicates that the watch is in the power recovery mode.
Illumination, alarm, countdown timer alarm, hourly time signal, and sensor
operations will be disabled until battery power recovers.
· Battery power will recover in about 15 minutes. At this time, the recovery
indicator (RECOVER) will stop flashing. This indicates that the functions
listed above are enabled again.
· Frequent flashing of the recovery indicator (RECOVER) indicates that battery
power is low. Expose the watch to bright light as soon as possible.
· Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass
Mode, Barometer Mode, Thermometer Mode or Altimeter Mode sensor may be
disabled if there is not enough power available. This is indicated when the
recovery indicator (RECOVER) is flashing.
· Frequent flashing of the recovery indicator (RECOVER) probably means that
remaining battery power is low. Leave the watch in bright light to allow it to
charge.

Taking Direction Readings
You can use the Digital Compass Mode to determine the direction of north, and
to check your bearing to a destination. · For information about what you can
do to improve digital compass reading accuracy, see “Calibrating
the Bearing Sensor” (page E-35) and “Digital Compass Precautions” (page E-39).
To take a direction reading 1. Make sure the watch is in the Timekeeping,
Digital Compass, or Altimeter Mode (page E-20).
2. Place the watch on a flat surface. If you are wearing the watch, make sure
that your wrist is horizontal (in relation to the horizon).
3. Point the 12 o’clock position of the watch in the direction whose reading
you want to take.
4. Press C to start. · COMP will appear in the display to indicate that a
digital compass operation is in progress. · Starting a digital compass
operation will cause the second hand to move momentarily to the 12 o’clock
position. After that, it will indicate magnetic north.

Note · The watch will return to the Timekeeping Mode about 60 seconds after
the direction reading
operation is complete. · To restart a reading operation from the beginning,
press C. · Pressing B will return to the Timekeeping Mode even is a reading
operation is in progress.
Important! · If the second hand does not point exactly at 12 o’clock after you
perform step 4 above, perform the
operation under “Hand Home Position Adjustment” (page E-29) to adjust it. · If
the digital display contents start to flash after you perform a reading
operation, it means that
abnormal magnetism has been detected. Move away from any potential source of
strong magnetism and try taking a reading again. If the problem occurs when
you try again, continue to keep away from the source of strong magnetism,
perform bidirectional calibration, and then try taking a reading again. For
more information, refer to “To perform bidirectional calibration” (page E-37)
and “Location” (page E-40).
Digital Compass Readings · After the first reading is obtained, the watch will
continue to take digital compass readings automatically
each second for up to 60 seconds. After that, the reading operation will stop
automatically. · The margin of error for the angle value and the direction
indicator is ±11 degrees while the watch is
horizontal (in relation to the horizon). If the indicated direction is
northwest (NW) and 315 degrees, for example, the actual direction can be
anywhere from 304 to 326 degrees. · Note that taking a direction reading while
the watch is not horizontal (in relation to the horizon) can result in large
direction reading error. · You can calibrate the bearing sensor if you suspect
the direction reading is incorrect.
E-34
Precautions about bidirectional calibration · You can use any two opposing
directions for bidirectional calibration. You must, however, make sure
that they are 180 degrees opposite each other. Remember that if you perform
the procedure incorrectly, you will get wrong bearing sensor readings. · Do
not move the watch while calibration of either direction is in progress. · You
should perform bidirectional calibration in an environment that is the same as
that where you plan to be taking direction readings. If you plan to take
direction readings in an open field, for example, calibrate in an open field.
Bearing Angle to Objective
E-33
· Any ongoing direction reading operation is paused temporarily while the
watch is performing an alert operation (daily alarm, Hourly Time Signal,

direction reading operation resumes for its remaining duration after the
operation that caused it to pause is finished.
Calibrating the Bearing Sensor You should calibrate the bearing sensor
whenever you feel that the direction readings being produced by the watch are
off. You can use any one of two different bearing sensor calibration methods:
bidirectional calibration or magnetic declination correction.
· Bidirectional Calibration Bidirectional calibration calibrates the bearing
sensor in relation to magnetic north. Use bidirectional calibration when you
want to take readings within an area exposed to magnetic force. This type of
calibration should be used if the watch becomes magnetized for any reason.
Important! · To ensure correct direction readings by this watch, be sure to
perform bidirectional calibration before
using it. The watch may produce incorrect direction readings if you do not
perform bidirectional calibration.
· Magnetic Declination Correction With magnetic declination correction, you
input a magnetic declination angle (difference between magnetic north and true
north), which allows the watch to indicate true north. You can perform this
procedure when the magnetic declination angle is indicated on the map you are
using. Note that you can input the declination angle in whole degree units
only, so you may need to round off the value specified on the map. If your map
indicates the declination angle as 7.4°, you should input 7°. In the case of
7.6° input 8°, for 7.5° you can input 7° or 8°.

Setting a map and finding your current location
Having an idea of your current location is important when mountain climbing or
hiking. To do this, you need to “set the map”, which means to align the map so
the directions indicated on it are aligned with the actual directions of your
location. Basically what you are doing is aligning north on the map with north
as indicated by the watch. · Note that map reading skills and experience are
required to determine your current location and
destination on a map.
Digital Compass Precautions
Magnetic North and True North
True north
The northerly direction can be expressed either as magnetic north or true north, which are different from each other. Also, it is important to keep in
Magnetic north
mind that magnetic north moves over time. · Magnetic north is the north that is indicated by the needle of a
compass.
· True north, which is the location of the North Pole of the Earth’s axis, is
the north that is normally indicated on maps.
Earth
· The difference between magnetic north and true north is called the “declination”. The closer you get to the North Pole, the greater the
declination angle.

Location
· Taking a direction reading when you are near a source of strong magnetism
can cause large errors in readings. Because of this, you should avoid taking
direction readings while in the vicinity of the following types of objects:
permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal
doors, lockers, etc.), high tension wires, aerial wires, household appliances
(TVs, personal computers, washing machines, freezers, etc.).
· Accurate readings are also impossible indoors, especially inside
ferroconcrete structures. This is because the metal framework of such
structures picks up magnetism from appliances, etc.
· Accurate direction readings are impossible while in a train, boat, air
plane, etc.
Storage
· The precision of the bearing sensor may deteriorate if the watch becomes
magnetized. Because of this, you should store the watch away from magnets or
any other sources of strong magnetism, including: permanent magnets (magnetic
necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), and
household appliances (TVs, personal computers, washing machines, freezers,
etc.).
· Whenever you suspect that the watch may have become magnetized, perform the
procedure under “To perform bidirectional calibration” (page E-37).
Specifying Altitude, Barometric Pressure, and Temperature Units
Use the procedure below to specify the altitude, barometric pressure, and temperature units to be used in the Altimeter Mode, Barometer Mode and the Thermometer Mode.
Important!
· When TYO (Tokyo) is selected as the Home City, the altitude unit is set
ll
automatically to meters (m), the barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These
lll
settings cannot be changed.
To specify altitude, barometric pressure, and temperature units 1. Make sure
the watch is in the mode for the type of unit you want to
specify (Altimeter, Barometer, or Thermometer Mode). · For information about
changing modes, see “Selecting a Mode”
(page E-20).

E-41
Using the Altimeter Mode
The watch takes altitude readings and displays results based on air pressure
measurements taken by a built-in pressure sensor. It also saves various types
of altitude records and data. · The displayed altitude reading is a relative
altitude that is calculated based on measurement of
changes in barometric pressure by the watch’s pressure sensor. This means that
barometric pressure changes can cause readings taken at different times at the
same location to be different. Also note that the value displayed by the watch
may be different from the actual elevation and/or sea level elevation
indicated for the area where you are located. When using the watch’s altimeter
while mountain climbing, it is recommended that you perform regular
calibration in accordance with the local altitude (elevation) indications.
Important! · See “To specify a reference altitude value” (page E-46) and
“Altimeter Precautions” (page E-56) for information
about how to minimize differences between readings produced by the watch and
values provided by local altitude (elevation) indications.
Getting Ready Before actually taking an altitude reading you need to select an
altitude reading interval.
Selecting the Altitude Auto Reading Interval You can select either of the
following two altitude auto reading interval.
0’05: Readings at one-second intervals for the first three minutes, and then
every five seconds for approximately the next hour
2’00: Readings at one-second intervals for the first three minutes, and then
every two minutes for approximately the next 12 hours
E-42
Note
· If you do not perform any button operation while in the Altimeter Mode, the
watch will return to the Timekeeping Mode automatically after 12 hours
(altitude auto reading interval: 2’00) or after one hour (altitude auto
reading interval: 0’05).
To specify the altitude auto reading interval

Using Reference Altitude Values
To minimize the chance of reading error, you should update the reference
altitude value before setting off on a trek or any other activity where you
plan to take altitude readings. During a trek, keep checking the readings
produced by the watch against altitude information provided by markers and
other information, and update the reference altitude value as required. ·
Reading error can be caused by changes in barometric pressure, atmospheric
conditions, and
elevation. · Before performing the procedure below, look up the altitude of
your current location on a map, the
Internet, etc.

Advanced Altimeter Mode Operations
Use the information in this section to obtain more accurate altimeter
readings, especially while mountain climbing or trekking.
Using an Altitude Differential Value
Altitude differential
If you specify a reference altitude, the second hand of the watch will indicate the difference between the current altitude and the reference
altitude. The displayed altitude differential value is updated each time the
watch obtains a new altitude reading value.
· Depending on the currently selected display range, the allowable
range for the altitude differential value is 100 meters to 100 meters
(100 meters = 328 feet), or 1,000 meters to 1,000 meters (1,000
meters = 3,280 feet).
· If a reading value is outside the allowable range either OVER ( ) or
UNDER ( ) appears on the digital display.
· The second hand will move to 9 o’clock if a sensor reading could not
be taken for some reason or if the reading is outside the allowable
range.

Types of Altitude Data
Your watch can record two types of altitude data in its memory: manually saved
data and auto save values. · Use the Data Recall Mode to view data stored in
memory. See “Viewing Altitude Records” (page E-70) for
details.
Manually Saved Records
Any time you perform the procedure below in the Altimeter Mode, the watch will
create and store a record with the currently displayed altitude reading, along
with the date and time the reading was taken. There is enough memory to store
up to 30 manually saved records, which are numbered from -01- through -30-.
To save a reading manually
1. In the Altimeter Mode, check to make sure that an altitude reading is on
the display. · If an altitude reading is not displayed, press A to take one.
See “To take altitude readings” (page E-44) for details.
2. Hold down A until REC flashes and then stops flashing. · This will save
the currently displayed altitude reading in a manually saved record, along
with the time and date of the reading. · The watch will return to the
Altimeter Mode screen automatically after the save operation is complete. ·
There is enough memory to store up to 30 manually saved records. If there are
already 30 manually saved records in memory, the above operation will cause
the oldest record to be deleted automatically to make room for the new one.
E-51
Auto Save Values Auto save values are one type of data stored in the memory of
your watch.
Auto Save Values
High Altitude (MAX) Low Altitude (MIN) Total Ascent (ASC) Total Descent (DSC)
· These values are checked and updated automatically by the watch as altitude
auto measurements are taken.
· Auto save is performed only while the watch is in the Altimeter Mode. ·
Cumulative ascent and cumulative descent values are updated whenever there is
a difference of at
least ±15 meters (±49 feet) from one reading to the next. · Auto save values
also include the date and time each value was recorded.
How High and Low Altitude Values are Updated With each auto save reading, the
watch compares the current reading against the MAX (high altitude) and MIN
(low altitude) values. It will replace the MAX value if the current reading is
at least 15 meters (±49 feet) greater than MAX, or the MIN value if the
current reading is at least 15 meters (±49 feet) less than MIN.
How Cumulative Ascent and Cumulative Descent Values Are Updated

The total ascent and total descent values produced by an Altimeter Mode
reading operation session during the example climb illustrated above are
calculated as follows.
Total Ascent: q (300 m) + e (620 m) = 920 m Total Descent: w (320 m) + r (500
m) = 820 m
E-52
· Entering the Altimeter Mode starts a new altitude auto reading session, but
it does not reset the current ASC and DSC values or change them in any way.
This means that the starting ASC and DSC values for a new Altimeter Mode auto
reading session are the values that currently are in memory. Each time you
complete an altitude auto reading session by exiting the Altimeter Mode, the
total ascent value of the current session (920 meters in the above example) is
added to the session’s starting ASC value. Also, the total descent value of
the current auto reading session (820 meters in the above example) is added
to the session’s starting DSC value.
Note · The high altitude, low altitude, total ascent, and total descent values
are retained in memory when you
exit the Altimeter Mode. To clear values, perform the procedure under “To
delete a specific record” (page E-73).
E-53
How does the altimeter work?
Generally, air pressure decreases as altitude increases. This watch bases its
altitude readings on International Standard Atmosphere (ISA) values stipulated
by the International Civil Aviation Organization (ICAO). These values define
relationships between altitude and air pressure. · Note that the following
conditions will prevent you from obtaining accurate readings:
When air pressure changes because of changes in the weather Extreme
temperature changes When the watch itself is subjected to strong impact
There are two standard methods of expressing altitude: absolute altitude,
which expresses an absolute height above sea level, and relative altitude,
which expresses the difference between the altitudes of two different places.
This watch expresses altitudes as relative altitude.
Height of building 130 m (relative altitude)
Rooftop at an altitude of 230 m above sea level (absolute altitude)
Sea Level
Regular calibration of the watch in accordance with values provided by local
altitude (elevation) indications is recommended before taking readings in
order to maximize reading accuracy (page E-45).
E-54
E-55
Operation Guide 5497
Altimeter Precautions
· This watch estimates altitude based on air pressure. This means that
altitude readings for the same location may vary if air pressure changes.
· Do not use this watch for altitude reading or perform button operations
while sky diving, hang gliding, or paragliding, while riding a gyrocopter,
glider, or any other aircraft, or while engaging in any other activity where
there is the chance of sudden altitude changes.
· Do not use this watch for measuring altitude in applications that demand
professional or industrial level precision.
· Remember that the air inside of a commercial aircraft is pressurized.
Because of this, the readings produced by this watch will not match the
altitude readings announced or indicated by the flight crew.
Precautions Concerning Simultaneous Altitude and Temperature Readings
For the more accurate altitude readings, leaving the watch on your wrist is
recommended in order to maintain the watch at a constant temperature. · When
taking temperature readings, keep the watch at as stable a temperature as
possible. Changes in
temperature can affect temperature readings. See product specifications (page
E-95) for sensor accuracy information.

measured
barometric pressure falls outside the range of 260 hPa to 1,100 hPa (7.65 inHg
to 32.45 inHg). The barometric pressure value will reappear as soon as the
measured barometric pressure is within the allowable range.
Display Units You can select either hectopascals (hPa) or inchesHg (inHg) as
the display unit for the measured barometric pressure. See “To specify
altitude, barometric pressure, and temperature units” (page E-41).

next to it. Each dot represents 1 hPa.
The following shows how to interpret the data that appears on the barometric pressure graph.
Rising barometric pressure indicates that upcoming weather will improve.
Falling barometric pressure indicates that upcoming weather will deteriorate.
Note
· If there are sudden changes in weather or temperature, the graph line of
past readings may run off the top or bottom of the display.
· The following conditions cause the barometric pressure reading to be

Barometric Pressure Change Indications
Your watch analyzes past barometric pressure readings and uses a barometric
pressure change indicator to inform you about changes in pressure. If the
watch detects a significant change in barometric pressure, it will beep and
display a flashing arrow that indicates the direction of the pressure change.
This means you could start taking barometric pressure readings after reaching
a lodge or camp area, and then check the watch the next morning for changes in
pressure, and plan you day’s activities accordingly. Note that you can enable
or disable display of the barometric pressure change indicator as desired. The
barometric pressure change indicator is displayed in the Barometer Mode and
while the barometric pressure graph is displayed in the Timekeeping Mode (page
E-23).

Important! · To ensure proper results, take barometric readings under
conditions where the altitude remains
constant.
Example In a lodge or campground On the ocean
· A change in altitude causes a change in barometric pressure. Because of
this, correct readings are impossible. Do not take readings while ascending or
descending a mountain, etc.
Enabling or Disabling Display of the Barometric Pressure Change Indicator You
can enable or disable display of the barometric pressure change indicator as
desired. When display of the indicator is enabled, the watch will take a
barometric pressure reading every two minutes, regardless of the mode it is
in. · When BARO is shown on the display, it means that barometric pressure
change indicator display is
enabled. · When BARO is not on the display, it means that barometric pressure
change indicator display is
disabled.
To enable or disable the barometric pressure change indicator In the Barometer
Mode, hold down D for at least two seconds. Wait until INFO appears on the
left side of the display and the current setting (ON or OFF) flashes on the
right. Use this screen to enable or disable the barometric pressure change
indicator. · If barometric pressure change indicator display is currently
enabled, BARO will also appear in the
display. BARO will not appear if display is currently disabled. · Note that
barometric pressure change indicator display will turn off automatically 24
hours after you
turn it on or battery power goes low.

· Note that power saving (page E-18) is disabled while barometric pressure
change indicator display is enabled.
· Note that barometric pressure change indicator display cannot be enabled
while the watch’s battery is low.
Pressure Sensor Calibration The pressure sensor built into the watch are
calibrated at the factory and normally require no further adjustment. If you
notice serious errors in the pressure readings produced by the watch, you can
calibrate the sensor to correct the errors. Important! · Incorrectly
calibrating the barometric pressure sensor can result in incorrect readings.
Before
performing the calibration procedure, compare the readings produced by the
watch with those of another reliable and accurate barometer.

Temperature Sensor Calibration
The temperature sensor built into the watch is calibrated at the factory and
normally requires no further adjustment. If you notice serious errors in the
temperature readings produced by the watch, you can calibrate the sensor to
correct the errors.
Important!
· Incorrectly calibrating the temperature sensor can result in incorrect
readings. Carefully read the following before doing anything. Compare the
readings produced by the watch with those of another reliable and accurate
thermometer. If adjustment is required, remove the watch from your wrist and
wait for 20 or 30 minutes to give the temperature of the watch time to
stabilize.
To calibrate the temperature sensor
1. Take a reading with another measurement device to determine the exact
current temperature.
2. Use B to enter the Thermometer Mode (TEMP), as shown on page E-20.

Illumination Precautions · The LED that provides illumination loses power
after very long use. · Illumination may be hard to see when viewed under
direct sunlight. · Illumination turns off automatically whenever an alarm
sounds. · Frequent use of illumination runs down the battery.
Auto light switch precautions · Wearing the watch on the inside of your wrist,
movement of your arm, or vibration of your arm can
cause frequent activation of the auto light switch and illumination of the
display. To avoid running down the battery, turn off the auto light switch
whenever engaging in activities that might cause frequent illumination of the
display. · Note that wearing the watch under your sleeve while the auto light
switch is turned on can cause frequent illumination of the display and can run
down the battery.
· Illumination may not turn on if the face of the watch is more than 15
degrees above or below parallel. Make sure that the back of your hand is
parallel to the ground.
· Illumination turns off after the preset illumination duration (page E-85),
even if you keep the watch pointed towards your face.
· Static electricity or magnetic force can interfere with proper operation of
the auto light switch. If illumination does not turn on, try moving the watch
back to the starting position (parallel with the ground) and then tilt it back
towards your face again. If this does not work, drop your arm all the way down
so it hangs at your side, and then bring it back up again.
· You may notice a very faint clicking sound coming from the watch when it is
shaken back and forth. This sound is caused by mechanical operation of the
auto light switch, and does not indicate a problem with the watch.

Troubleshooting
Time Setting The current time setting is off by hours. Your Home City setting
may be wrong (page E-24). Check your Home City setting and correct it, if
necessary.
The current time setting is off by one hour. You may need to change your Home
City’s standard time/daylight saving time (DST) setting. Use the procedure
under “To change the current time and date settings” (page E-26) to change the
standard time/ daylight saving time (DST) setting.
Altitude Readings Altitude readings produce different results at the same
location.
Readings produced by the watch are different from the elevation and/or sea
level altitude indications in my area. (Negative sea level altitude values are
produced in a location where the indicated elevation is a positive value.)
I can’t get correct altitude readings. Relative altitude is calculated based
on changes in barometric pressure measurement by its pressure sensor. This
means that barometric pressure changes can cause readings taken at different
times at the same location to be different. Also note that the value displayed
by the watch may be different from the actual elevation and/or sea level
elevation indicated for the area where you are located. When using the watch’s
altimeter while mountain climbing, you need to be sure to perform regular
calibration in accordance with the local altitude (elevation) indications. For
more information, see “To specify a reference altitude value” (page E-46).
E-90
Following a relative altitude reading, the watch’s second hand points to 9
o’clock.
· The reading value is outside of the allowable measurement range (page E-44).
· This could indicate sensor error. If ERR (error) is on the digital display,
refer to “Direction, Altitude,
Barometric Pressure, and Temperature Readings” (page E-93) for more
information.

Taking Direction Readings
lll ll
ll
Abnormal magnetism detection is indicated.
· Move away from any potential source of strong magnetism and try taking a
reading again.
· If abnormal magnetism is detected again when you retry, it could mean that
the watch itself has become magnetized. If this happens, continue to keep away
from the source of strong magnetism, perform bidirectional calibration, and
then try taking a reading again. For more information, refer to “To perform
bidirectional calibration” (page E-37) and “Location” (page E-40).
ERR appears on the digital display during sensor reading operations.
There is something wrong with the sensor. This could be due to nearby strong
magnetic force. Move location where magnetism is not present and try again.
If, after multiple retries, ERR keeps appearing, contact your original
retailer or CASIO service center. See “Location” (page E-40).
E-91
ERR appears following bidirectional calibration. If the screen displays
hyphens (- – -) followed by the ERR (error) indicator, it could mean there is
something wrong with the sensor. · Wait for about one second for the ERR
indicator to disappear from the display, and then calibrate the
sensor again. · If ERR continues to appear even after multiple attempts to
calibrate, contact your original retailer or
CASIO service center.
The direction information indicated by the watch is different from that
indicated by a backup compass.
· Move away from any potential source of strong magnetism, perform
bidirectional calibration, and then try taking a reading again. For more
information, refer to “To perform bidirectional calibration” (page E-37) and
“Location” (page E-40).
Direction readings produce different results at the same location. · Move away
from any potential source of strong magnetism and try taking a reading again.
See
“Location” (page E-40).
I am having problems taking direction readings indoors. · Move away from any
potential source of strong magnetism and try taking a reading again. See
“Location” (page E-40).
Whenever you have a sensor malfunction, take the watch to your original
retailer or nearest authorized CASIO distributor as soon as possible.
Barometric Pressure Readings
Following a relative barometric pressure reading, the watch’s second hand
points to 9 o’clock. · The reading value is outside of the allowable
measurement range (page E-62). · There may be a problem with the sensor. If
ERR (error) is on the digital display, refer to “Direction,
Altitude, Barometric Pressure, and Temperature Readings” for more information.
Direction, Altitude, Barometric Pressure, and Temperature Readings
ERR appears on the digital display during sensor reading operations. This
indicates that there is a problem with the sensor, making sensor readings
impossible. · If the error is indicated while a reading operation in progress,
restart the operation. If ERR appears
again, it could mean there is something wrong with the sensor. · If ERR
appears frequently, it could mean that the sensor is faulty. Contact your
original retailer or
CASIO service center
I can’t change the temperature, barometric pressure, and altitude display
units. When TYO (Tokyo) is selected as the Home City, the altitude unit is set
automatically to meters (m), the barometric pressure unit to hectopascals
(hPa), and the temperature unit to Celsius (°C). These settings cannot be
changed.
World Time Mode
The time for my World Time City is off in the World Time Mode. This could be
due to incorrect switching between standard time and daylight saving time. See
“To configure World Time City and summer time settings” (page E-82) for more
information.
E-92
Charging The watch does not resume operation after I expose it to light. This
can happen after the power level drops to Level 5 (page E-14). Keep the watch
exposed to light until it recharges sufficiently.
RECOVER is flashing on the digital display. The watch is in the charge
recovery mode. Wait until the recovery process is complete (about 15 minutes).
The watch will recover more quickly if you place it in a brightly lit
location.
Note · Performing repeated illumination and/or sensor reading operations over
a short time period can cause
a sudden drop in watch’s charge. This will cause the watch to enter the charge
recovery mode. The watch is in the charge recovery mode when RECOVER is
flashing on the digital display. The charge recovery mode is the same as a low
battery charge state, access to some functions is limited while the watch
charge is recovering. Normal operation will resume after recovery is complete.
For more information, refer to “Power Recovery Mode” (page E-16). · A flashing
CHARGE indicator means that the charge level of the watch has suddenly
dropped. Immediately expose the watch to light to charge it.
