Do not use your watch for scuba diving or other types of diving that requires air tanks.
Watches that do not have WATER RESIST or WATER RESISTANT marked on the back cover are not protected against the effects of sweat. Avoid using such a watch under conditions where it will be exposed to large amounts of sweat or moisture, or to direct splashing with water.
Even if a watch is water resistant, note the usage precautions described below. Such types of use reduce water resistance performance and can cause fogging of the glass. Do not operate the crown or buttons while your watch is submersed in water or wet. Avoid wearing your watch while in the bath. Do not wear your watch while in a heated swimming pool, sauna, or any other high temperature/high humidity environment. Do not wear your watch while washing your hands or face, while doing housework, or while performing any other task that involves soaps or detergents.
After submersion in seawater, use plain water to rinse all salt and dirt from your watch.
To maintain water resistance, have the gaskets of your watch replaced periodically (about once every two or three years).
A trained technician will inspect your watch for proper water resistance whenever you have its battery replaced. Battery replacement requires the use of special tools. Always request battery replacement from your original retailer or from an authorized CASIO service center.
Some water-resistant watches come with fashionable leather bands. Avoid swimming, washing, or any other activity that causes direct exposure of a leather band to water.

The inside surface of the watch glass may fog when the watch is exposed to a sudden drop in temperature. No problem is indicated if the fogging clears up relatively quickly. Sudden and extreme temperature changes (such as coming into an air conditioned room in the summer and standing close to an air conditioner outlet, or leaving a heated room in the winter and allowing your watch to come into contact with snow) can cause it to take longer for glass fogging to clear up. If glass fogging does not clear up or if you notice moisture inside of the glass, immediately stop using your watch and take it to your original retailer or to an authorized CASIO service center.
Your water-resistant watch has been tested in accordance with International Organization for Standardization regulations.
Band
Tightening the band too tightly can cause you to sweat and make it difficult for air to pass under the band, which can lead to skin irritation. Do not fasten the band too tightly. There should be enough room between the band and your wrist so you can insert your finger.
Deterioration, rust, and other conditions can cause the band to break or come off of your watch, which in turn can cause band pins to fly out of position or to fall out. This creates the risk of your watch falling from your wrist and becoming lost, and also creates the risk of personal injury. Always take good care of your band and keep it clean.
Immediately stop using a band if you even notice any of the following: loss of band flexibility, band cracks, band discoloration, band looseness, band connecting pin flying or falling out, or any other abnormality. Take your watch to your original retailer or to a CASIO service center for inspection and repair (for which you will be charged) or to have the band replaced (for which you will be charged).

Watch Operation Guide 5713

Temperature
Never leave your watch on the dashboard of a car, near a heater, or in any other location that is subject to very high temperatures. Do not leave your watch where it will be exposed to very low temperatures. Temperature extremes can cause your watch to lose or gain time, to stop, or otherwise malfunction.
Leaving your watch in an area hotter than +60 °C (140 °F) for long periods can lead to problems with its LCD. The LCD may become difficult to read at temperatures lower than 0 °C (32 °F) and greater than +40 °C (104 °F).
Impact
Your watch is designed to withstand impact incurred during normal daily use and during light activity such as playing catch, tennis, etc. Dropping your watch or otherwise subjecting it to strong impact, however, can lead to malfunction. Note that watches with shock-resistant designs (G-SHOCK, BABY-G, G-MS) can be worn while operating a chain saw or engaging in other activities that generate strong vibration, or while engaging in strenuous sports activities (motocross, etc.)
Magnetism
The hands of analog and combination (analog-digital) watches are moved by a motor that uses magnetic force. When such a watch is close to a device (audio speakers, magnetic necklace, cell phone, etc.) that emits strong magnetism, the magnetism can cause timekeeping to slow down, speed up, or stop, resulting in the incorrect time being displayed.
Timekeeping accuracy may be affected if the watch itself becomes magnetized. Also, very strong magnetism (from medical equipment, etc.) should be avoided because it can cause malfunction of your watch and damage to electronic components.
Electrostatic Charge
Exposure to very strong electrostatic charge can cause your watch to display the wrong time. Very strong electrostatic charge even can damage electronic components.
Electrostatic charge can cause the display to go blank momentarily or cause a rainbow effect on the display.

Chemicals
Do not allow your watch to come into contact with thinner, gasoline, solvents, oils, or fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain such ingredients. Doing so can cause discoloration of or damage to the resin case, resin band, leather, and other parts.
Storage
If you do not plan to use your watch for a long time, thoroughly wipe it free of all dirt, sweat, and moisture, and store it in a cool, dry place.
Resin Components
Allowing your watch to remain in contact with other items or storing it together with other items for long periods while it is wet can cause color on resin components to transfer to the other items, or the color of the other items to transfer to the resin components of your watch. Be sure to dry off your watch thoroughly before storing it and make sure it is not in contact with other items.
Leaving your watch where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from your watch for long periods can cause it to become discolored.
Friction caused by certain conditions (strong external force, sustained rubbing, impact, etc.) can cause discoloration of painted components.
If there are printed figures on the band, strong rubbing of the printed area can cause discoloration.
Leaving your watch wet for long periods can cause fluorescent color to fade. Wipe the watch dry as soon as possible after it becomes wet.
Semi-transparent resin parts can become discolored due to sweat and dirt, and if exposed to high temperatures and humidity for long periods.
Daily use and long-term storage of your watch can lead to deterioration, breaking, or bending of resin components. The extent of such damage depends on usage conditions and storage conditions.

Leather Band
Allowing your watch to remain in contact with other items or storing it together with other items for long periods while it is wet can cause the color of the leather band to transfer to the other items or the color of the other items to transfer to the leather band. Be sure to dry off your watch thoroughly with a soft cloth before storing it and make sure it is not in contact with other items.
Leaving a leather band where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from a leather band for long periods can cause it to become discolored.
CAUTION: Exposing a leather band to rubbing or dirt can cause color transfer and discoloration.
Metal Components
Failure to clean dirt from metal components can lead to formation of rust, even if components are stainless steel or plated. If metal components exposed to sweat or water, wipe thoroughly with a soft, absorbent cloth and then place the watch in a well-ventilated location to dry.
Use a soft toothbrush or similar tool to scrub the metal with a weak solution of water and a mild neutral detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing metal components, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.
Bacteria and Odor Resistant Band
The bacteria and odor resistant band protects against odor generated by the formation of bacteria from sweat, which ensures comfort and hygiene. In order to ensure maximum bacteria and odor resistance, keep the band clean. Use an absorbent soft cloth to thoroughly wipe the band clean of dirt, sweat, and moisture. A bacteria and odor resistant band suppresses the formation of organisms and bacteria. It does not protect against rash due to allergic reaction, etc.

Liquid Crystal Display
Display figures may be difficult to read when viewed from an angle.
Watch with Data Memory
Allowing the battery to go dead, replacing the battery, or having your watch repaired can cause all data in watch memory to be lost. Note that CASIO Computer Co., Ltd. assumes no responsibility for any damages or losses caused by data lost due to malfunction or repair of your watch, replacement of the battery, etc. Be sure to keep separate written copies of all important data.
Watch Sensors
A watch sensor is a precision instrument. Never try to take it apart. Never try to insert any objects into the openings of a sensor, and take care to ensure that dirt, dust, or other foreign matter does not get into it. After using your watch where it has been immersed in saltwater, rinse it thoroughly with fresh water.
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.

User Maintenance
Caring for Your Watch
Remember that you wear your watch next to your skin, just like a piece of clothing. To ensure your watch performs at the level for which it is designed, keep it clean by frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat, water and other foreign matter.
Whenever your watch is exposed to sea water or mud, rinse it off with clean fresh water.
For a metal band or a resin band with metal parts, use a soft toothbrush or similar tool to scrub the band with a weak solution of water and a mild neutral detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing the band, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.
For a resin band, wash with water and then wipe dry with a soft cloth. Note that sometimes a smudge like pattern may appear on the surface of a resin band. This will not have any effect on your skin or clothing. Wipe with a cloth to remove the smudge pattern.
Clean water and sweat from a leather band by wiping with a soft cloth.
Not operating a watch crown, buttons, or rotary bezel could lead to later problems with their operation. Periodically rotate the crown and rotary bezel, and press buttons to maintain proper operation.

Dangers of Poor Watch Care
Rust
Though the metal steel used for your watch is highly rust-resistant, rust can form if your watch is not cleaned after it becomes dirty. Dirt on your watch can make it impossible for oxygen to come into contact with the metal, which can lead to breakdown of the oxidization layer on the metal surface and the formation of rust.
Rust can cause sharp areas on metal components and can cause band pins to fly out of position or to fall out. If you ever notice any abnormality immediately stop using your watch and take it to your original retailer or to an authorized CASIO service center.
Even if the surface of the metal appears clean, sweat and rust in crevasses can soil the sleeves of clothing, cause skin irritation, and even interfere with watch performance.
Premature Wear
Leaving sweat or water on a resin band or bezel, or storing your watch an area subject to high moisture can lead to premature wear, cuts, and breaks.
Skin Irritation
Individuals with sensitive skin or in poor physical condition may experience skin irritation when wearing a watch. Such individuals should keep their leather band or resin band particularly clean. Should you ever experience a rash or other skin irritation, immediately remove your watch and contact a skin care professional.

Watch Operation Guide 5713

Battery
The special rechargeable battery used by your watch is not intended to be removed or replaced by you. Use of a rechargeable battery other than the special one specified for your watch can damage your watch.
The rechargeable (secondary) battery is charged when the solar panel is exposed to light, so it does not require regular replacement as the primary battery requires. Note, however, that long use or operating conditions can cause the capacity or charging efficiency of the rechargeable battery to deteriorate. If you feel that the amount of operation provided by charging is too short, contact your original retailer or CASIO service center.

Overview The watch’s time and day settings can be configured in accordance with a received time calibration signal.
Important!
In order to make it possible for the current time setting to be adjusted correctly based on time calibration signal reception, you need to specify the time zone where you are using the watch.
If the watch was unable to connect with a phone even once for time adjustment during the previous day while connection with a phone is being used, it will automatically try to receive a time calibration signal.
Note
Areas where time calibration signal reception is supported are limited. When the watch is in an area where time calibration signal reception is not possible, connect with a phone to adjust time and day settings. l Time Signal Reception Ranges

Appropriate Signal Reception Location A time calibration signal can be received while the watch is near a window. Position the watch so its 12 o’clock side is facing the window. Keep metal objects away from the watch. Do not move the watch. Do not perform any operation on the watch.
12 o’clock
Note
You may experience time calibration signal reception problems in the areas described below. Among or near buildings While riding in a vehicle Near household appliances, office machines, mobile phones, etc. On a construction site, in an airport, or any other location where radio wave interference occurs Near high-voltage lines In mountainous areas or behind a mountain

Other than the above.
If you are unable to connect with a phone and are unable to receive a time signal, you can perform watch button operations to adjust its time setting. l Using Watch Operations to Adjust the

• 1 square (v) is 10 m.

Important!
The altitude readings displayed by the watch are relative values that are calculated based on barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes due to weather can cause altitude readings taken 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 regularly calibrate its readings in accordance with local altitude (elevation) indications. l Calibrating Altitude Readings (Offset)
The altitude correction value you specify and/or barometric pressure changes may cause a negative value to be displayed.

Measurement range: -700 to 10,000 meters (-2,300 to 32,800 feet) (Measurement unit: 1 meter (5 feet)) Note that calibrating altitude readings will cause a change in the measurement range.
[- – -] will appear for the measured value if it is outside the allowable range.

Calibrating Altitude Readings (Offset)
To minimize the difference between locally indicated and measured values, you should update the reference altitude value (offset) before setting off and during treks or any other activities where you take altitude readings.
Also, you can ensure accurate measurements by checking a map local altitude indications or some other source for your current location’s altitude, and regularly calibrating watch readings with the latest information while mountain climbing.
Note
You can find out the altitude at your current location from signs, maps, on the Internet, etc.
Differences between actual altitude and watch readings can be caused by the factors below. Changes in barometric pressure Changes in temperature caused by variations in barometric pressure and by elevation

Altitude Reading Precautions
Effects of Temperature
When taking altitude readings, take the steps below to keep the watch at as stable a temperature as possible. Changes in temperature can affect altitude readings.
Take readings with the watch on your wrist.
Take readings in an area where temperature is stable.
Altitude Readings
Do not use this watch while skydiving, hang gliding, paragliding, gyrocopter flying, glider flying, or engaged in other activities where altitude changes suddenly.
Altitude readings produced by this watch are not intended for special-purpose or industrial level use.
In an aircraft, the watch measures the incabin pressurized air pressure, so readings will not match altitudes announced by the crew.
Altitude Readings (Relative Altitude)
This watch uses International Standard Atmosphere (ISA) relative altitude data defined by the International Civil Aviation Organization (ICAO). Barometric pressure generally becomes lower as altitude increases.
Correct measurement may not be possible under the conditions below.
During unstable atmospheric conditions
During sudden temperature changes
After the watch has been subjected to strong impact

Precautions

Checking the Current Barometric Pressure
1. Enter the Barometer Mode. l Navigating Between Modes Entering the Barometer Mode starts measurement, and displays the barometric pressure at your current location and a barometric pressure graph. After you enter the Barometer Mode, the watch takes readings about every five seconds for three minutes. After that, a measurement is taken about every two minutes.
Barometric pressure graph
Barometric pressure
To retrigger measurement, press (A). To return to the Timekeeping Mode,
hold down (B) for at least two seconds.
Note
If the hour and/or minute hand is located over the digital display when you perform a barometric pressure measurement, the hands will temporarily shift to the 22-second or 38-second position to allow easier reading of measurement values. The hands will unshift to their normal positions after about three seconds.
When you enter the Barometer Mode, the function hand indicates the barometric pressure difference if the previous barometric pressure measurement was retained. l Checking the Change in Barometric Pressure between Two Readings
The watch will automatically return to the Timekeeping Mode from the Barometer mode if you do not perform any operation for about one hour.
The measurement range is 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg) (1 hPa (0.05 inHg) units). [- – -] will appear for the measured value if it is outside the allowable range.

Checking Changes in Barometric Pressure Over Time
The watch can be configured to show a graph of pressure readings taken every two hours or every two minutes. You can display a graph of barometric pressure readings for the past 20 hours or the past 20 minutes. The square (v) at the far right of the graph indicates the latest barometric pressure reading.
Barometric pressure (1 hPa scale)
Time (2-hour or 2-minute scale)
Changing the Measurement Interval of the Barometric Pressure Graph
You can select a measurement interval of two hours or two minutes for the barometric pressure graph. 1. Enter the Barometer Mode.
l Navigating Between Modes 2. Loosen the crown and then pull it out.
This displays the current barometric pressure.

Watch Operation Guide 5713

3. Press (B). This causes the current measurement interval to appear on the display.
4. Rotate the crown to select [0:02] or [2:00] as the measurement interval. [0:02]: When the measurement interval of the barometric pressure graph is two minutes, measurements are taken every five seconds. [2:00]: When the measurement interval of the barometric pressure graph is two hours, measurements are taken every two minutes.
5. Push the crown back in and then lock it.
Note
If you switch to the two-minute measurement interval graph, the watch will automatically return to the two-hour measurement interval graph after 24 hours.
Note that the graph will not be displayed immediately after it is switched to a two-minute measurement interval graph.

Predicting Upcoming Weather

A trend like this:

Means this:

Rising barometric pressure, which indicates that upcoming weather probably will be fair.

Falling barometric pressure, which indicates that upcoming weather probably will be bad.

Note

Large changes in barometric pressure and/or temperature can cause past data readings to be plotted outside of the visible area of the graph. Though plots are not visible, the data is still maintained in watch memory.
The barometric pressure graph is not displayed while Barometric Pressure Change Indications are displayed. l Sudden Barometric Pressure Change Indications

Checking the Change in Barometric Pressure between Two Readings

When you perform the procedure below in the Barometer Mode, the function hand will indicate the difference between the current barometric pressure measurement and the last auto measurement value (taken at twohour or two- minute intervals).

1. Enter the Barometer Mode. l Navigating Between Modes
The function hand indicates the barometric pressure differential (Barometric Pressure Differential Indicator).
Example: Barometric pressure differential of -3 hPa (-0.09 inHg) (two-hour measurement interval)

Unit: hPa

Range: ±10 hPa (±0.3 inHg)

Pressure Differential Indicator

Note
The function hand points to [OVER] if the pressure difference exceeds +10hPa (+0.3 inHg) and to [UNDER] if the pressure difference exceeds -10hPa (-0.3 inHg).
A reading outside the allowable measurement range of 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg) or any measurement error will cause the function hand to point to [0].

Watch Operation Guide 5713

Sudden Barometric Pressure Change Indications

Whenever the watch detects a significant change in air pressure readings (due to sudden ascent or descent, or to the passage of a low pressure or high pressure area), it will beep to let you know. An arrow will also flash on the display at this time if the watch is in the Barometer Mode, or if it is in the Timekeeping Mode with the barometric pressure graph displayed. The arrow that appears shows the direction of the pressure change. These alerts are called “Barometric Pressure Change Indications”.

This indicator:

Means this:

Sudden drop in pressure

Sudden rise in pressure
Sustained rise in pressure, shifting to a fall
Sustained fall in pressure, shifting to a rise
Important!
To ensure correct barometric pressure change indicator operation, enable it in a location where the altitude is constant (such as a lodge, camp area, or on the ocean).
A change in altitude causes a change in air pressure. Because of this, correct readings are impossible. Do not take readings while ascending or descending a mountain, etc.

1. Enter the Barometer Mode. l Navigating Between Modes
2. Hold down (D) for at least two seconds. If this turns on barometric pressure change indication, [INFO ON] will stop flashing and then the [BARO] indicator will appear on the display.
3. To disable barometric pressure change indication, hold down (D) again for at least two seconds.
Note
If Barometric Pressure Change Indications are on, barometric pressure readings are taken every two minutes even while the watch is not in the Barometer Mode.
The Barometric Pressure Change Indication becomes disabled automatically 24 hours after it is enabled.
You will not be able to turn on barometric pressure change indication if the watch’s battery level is low.
Low battery power will also cause barometric pressure change indication to turn off automatically.

Calibrating Barometric Pressure Readings (Offset)
The watch’s pressure sensor is adjusted at the factory and normally does not require calibration. However, you can calibrate the displayed value if you notice major errors in readings.
Important!
The watch will not be able to produce correct barometric pressure readings if you make a mistake during the calibration procedure. Check to make sure that the value you use for calibration produces correct pressure readings.
