FAQ

Q: What type of power supply does the watch use?

A: The watch uses a solar cell to generate electrical power, which is stored by a rechargeable battery.

Q: How can I ensure stable operation of the watch?

A: To ensure stable operation, expose the watch to light as much as possible when wearing or storing it. Avoid blocking the watch from light for long periods, as it can cause the rechargeable battery to run down.

Q: What happens when the battery level drops to Level 4?

A: When the battery level drops to Level 4, all functions, including timekeeping, are disabled. It is recommended to start charging the watch when the battery level reaches Level 3 and flashes.

Q: How can I start charging the watch?

A: Expose the watch to light for recharging as soon as possible after the Level 3 indicator starts to flash.

Power Saving

Power Saving causes the watch to enter a sleep state automatically and save power whenever the watch is left in the dark. The Power Saving feature of the watch is turned on at the factory.

Note that the watch may also enter the sleep state if the watch is blocked from light by your sleeve.

How the sleep state works

Display sleep state
The display sleep state is triggered whenever the watch is left in the dark for about one hour between the hours of 10:00 p.m. and 6:00 a.m.

• The display sleep state causes the display to go blank, except for a flashing Power Saving indicator. The alarm and the hourly time signal continue to operate normally while the watch is in the display sleep state.
• The watch will not enter the sleep state if it is in the Timer Mode or the Stopwatch Mode.

Function sleep state
The function sleep state is triggered whenever the watch is left in the dark for six or seven days. The power saving indicator stops flashing and remains on the display to indicate the function sleep state.

• The alarm and the hourly time signal are disabled while the watch is in the function sleep state, and time calibration signal auto receive is not performed.
• Digital timekeeping functions continue to operate normally in the function sleep state.

To recover from the sleep state

Move the watch to a brightly lit location or press any button. The watch will also recover from the sleep state if you angle it towards your eyes for reading (see “To illuminate the display with the auto light switch”).

It can take up to two seconds before display figures re-appear after you place the watch in a well-lit area.

To turn Power Saving on and off

Use the procedure under “Configuring Home Time Settings” to turn Power Saving on or off.

Leaving the watch in a drawer or anywhere else it is dark can cause Power Saving to trigger in order to conserve battery power.

LCD Types

This watch is available with either of two different LCD types: light background with dark figures (black-on-white) or dark background with light figures (white-on-black).
Note that all of the samples in this manual show the black-on-white type LCD.

Modes and Display Screens

Each press of the C button sounds a confirmation tone and cycles through available modes in the sequence shown below.

The display will revert to the Timekeeping Mode automatically if you leave the Alarm Mode screen displayed without performing any operation for about two or three minutes.

Power Supply

The power supply of this watch uses a solar cell to generate electrical power, which is stored by a rechargeable battery. Using or storing the watch where it is not regularly exposed to light, or allowing it to be blocked from light by your sleeve for long periods as you are wearing it can cause the power of the rechargeable battery to run down. To ensure stable operation, be sure to allow the watch to be exposed to light as much as possible when you are wearing or storing it.

Important!
Note that all data in memory and all settings are cleared whenever you allow the level of the rechargeable battery to drop to Level 4.

Flashing Recover Indicator

If you use the light or alarm a number of times during a short period, a recover (RECOV) indicator flashes on the display and the following operations become disabled as battery power recovers.

• Display illumination,
• Alarm and hourly time signal
• Time calibration signal reception
  Normal operation will return after the battery recovers.

Battery Level Indicator

• Exposing the watch to direct sunlight or other strong light may cause the battery level indicator to indicate a level momentarily that is higher than the actual battery level. Because of this, you should wait for a short while after charging to check the battery level indicator. Even after the battery drops to Level 4, you will be able to resume normal operation by charging the battery.
• When charging from Level 4, the display will start operating when the battery reaches Level 3. At this time you will be able to configure time and date settings, but you should keep the watch exposed to light until the battery reaches Level 2 or Level 1.

Start charging at Level 3!

Battery Level 3 indicates that remaining battery power is very low. Be sure to expose the watch to light for recharging as soon as possible after the Level 3 indicator starts to flash.

Charging Precautions

Avoid charging the watch in the following locations, and anywhere else where the watch may become very hot.

• On the dashboard of an automobile parked in the sun
• Very close to an incandescent light source or other sources of heat
• In a location exposed to direct sunlight for long periods
  Note that the display panel may become black under very high temperatures. This is temporary, and the display will appear normal again at lower temperatures.
  Depending on the light source you are using, the case of the watch may become quite hot during charging. Take care to guard against burn injury after charging.

To charge the battery

Point the solar panel (display) of the watch at a light source.
Remember that even a partial blockage of the solar cell reduces charging efficiency.
Example: Positioning the watch

Display Illumination

An EL (electroluminescent) panel is used to illuminate the display of the watch for easy reading in the dark. An auto light switch automatically illuminates the display when you angle the watch towards your eyes for reading.

To illuminate the display manually

Press the L button in any mode to illuminate the display of the watch.

• You can use the procedure under “To specify the illumination duration” to select either 1.5 seconds or 2.5 seconds for the illumination duration.
• Pressing the L button illuminates the display regardless of whether the auto light switch is on or off.
  You may hear a faint rattling sound when you move the watch around. This sound is caused by the movement of a metal bulb that controls operation of the auto light switch, and does not indicate malfunction.

To illuminate the display with the auto light switch

The auto light switch automatically illuminates the display whenever you angle the watch towards your eyes for reading, but only when it is dark.

• The auto light switch does not illuminate the display when surrounding light is bright.
  You can use the procedure under “To specify the illumination duration” to configure the illumination duration as approxi-mately 1.5 seconds or 2.5 seconds.

To turn the auto light switch on and off

While a setting screen (one on which a setting is flashing) is on the display, hold down the L button for about two seconds to toggle the auto light switch on (auto light switch on indicator displayed) and off (no indicator displayed).

Positioning Your Arm Correctly

• You should be wearing the watch on the outside of your wrist when using the auto light switch.
• Make sure that the left (9 o’clock) and right (3 o’clock) sides of the watch are within ±15 degrees of being parallel with the ground. The auto light switch may not operate properly if the angle is greater.

Important!

• The light may be difficult to see if you turn it on under bright sunlight.
• If you press any button or if an alarm operation starts while the display is illuminated, illumination will turn ofφ.
• Display illumination does not work while you are performing a time calibration signal manual receive operation.
• You may hear humming sound from the watch while the display is illuminated. This is caused by vibration of the EL panel used of illumination, and does not indicate malfunction.

Auto Light Precautions

• Frequent use of the auto light can run down the battery.
• The auto light switch may cause the display to illuminate when your sleeve covers the display of the watch.
• The display may not illuminate immediately when you angle the watch towards your face. This does not indicate malfunction.
• The display remains illuminated for the currently set duration (1.5 or 2.5 seconds) only, even if you leave the watch angled towards your face.
• The auto light switch is automatically disabled whenever battery power is at Level 3 or loweρ.
• The display may illuminate unintentionally when you wear the watch on the inside of your wrist, when you shake your arm, or when you raise your arm. Be sure to turn off the auto light switch whenever you do not need display illumination.
• Keep the auto light switch turned off whenever you are wearing the watch on the inside of your wrist.
• Electro-static charge and magnetism can interfere with auto light operation and even make operation impossible. If this happens lower your arm to the starting position and then raise it again. If you still have trouble with illumination, try lowering your arm down to your side and then raise it to your face for reading.

To specify the illumination duration

1. In the Timekeeping Mode, hold down A for about two seconds.
   This will cause your Home City code to flash on the display.

2. Press the C button three times to display the flashing seconds count.

3. Press the B button to toggle the illumination duration between about 1.5 seconds ( indicator) and 2.5 seconds ( indicator).

4. After the setting is the way you want, press the AAAAA button to exit the setting screen.
   The watch will also exit the setting screen automatically if you do not perform any operation for about two or three minutes.

How a Radio-controlled Watch Works

What is a radio-controlled watch?
Your radio-controlled watch is designed to receive a time calibration signal that contains standard time data, and adjust its current time setting accordingly.

After the watch receives the Standard Time signal, it performs internal calculations to determine the current time. Because of this, there may be an error of up to one second in the displayed time.

Calibration Signal

• The Japanese calibration signal (Call Sign: JJY) is maintained by the National Institute of Information and Communications Technology (NICT). It is a long wave signal transmitted 24 hours a day from the Mt. Otakadoya transmitter (40kHz) located in Tamura-gun, Fukushima Prefecture, and from the Mt. Hagane transmitter (60kHz) located on the border between Saga Prefecture and Fukuoka Prefecture.
• The U.S. calibration signal (Call Sign: WWVB) is transmitted by the National Institute of Standards and technology from Fort Collins, Colorado.
  Note that transmission of the time calibration signal may be interrupted occasionally due to maintenance, lightning, etc.

Reception Range
This watch is designed to receive the standard time calibration signal of Japan (JJY) or of the United States (WWVB). The signal that is received depends on the current Home City setting.

For information about selecting a Home City, see “Configuring Home Time Settings”. For information about city codes, see the “World Time City Code List”.

TYO, SEL

Either the Mt. Otakadoya signal (40kHz) or the Mt. Hagane signal (60kHz)

LAX, DEN, CHI, NYC

|

Fort Collins, Colorado signal

• Geographic contours, nearby buildings, seasonal conditions, the time of day, can even make reception impossible even when you are within range of the transmitter.
•  Best reception is possible late at night.

Location
Reception is difficult and may even be impossible in the locations described below. Avoid such locations when performing signal reception.

You should think of your watch operating like a radio or TV when it is receiving the calibration signal.

If you are experiencing problems with reception, move away from the types of locations described above to a location with better reception, and try again.

Receiving the Calibration Signal
There are two methods you can use to receive the time calibration signal.

Auto Receive (3 times per day)
When the Home City setting is TYO or SEL, the time calibration signal is received automatically at 1:00, 2:00, and 3:00 each morning.

• If both the 2:00 and 3:00 receive operations are unsuccessful, a receive operation is performed at 4:00. If receive is still unsuccessful, it is performed again at 5:00.
• If all five of the above receive operations are unsuccessful, a receive operation is performed again at midnight the following day.
• When the Home City is NYC, CHI, DEN, or LAX, auto receive is performed at midnight, and at 1:00 and 2:00 in the morning.
• If both the 1:00 and 2:00 receive operations are unsuccessful, a receive operation is performed at 3:00. If receive is still unsuccessful, it is performed again at 4:00.
• If all five of the above receive operations are unsuccessful, a receive operation is performed again at 5:00.

Manual receive (You initiate reception using a button operation.)

The watch is set up for auto receive at the factory, so all you need to do is to place it in a location that allows good reception each night.

To position the watch for optimum reception

Remove the watch from your wrist and place it somewhere so its top (12 o’clock side, where the antenna is located) is facing approximately in the direction of the signal transmitter. Keep the watch away from metal objects.

• Orienting the watch so it is sideways to the transmitter makes it more difficult to receive the signal.
• Do not move the watch while it is receiving the calibration signal.

Time Required for Reception

A calibration signal receive operation takes anywhere from about two to five minutes.

• Note that when “AUTO” (Auto Select) is specified as the transmitter selection mode, signal reception can take up to 12 minutes.
• See “Configuring Auto Receive Settings” for more information.

To perform manual receive
In the Timekeeping Mode, hold down the D button for about two seconds.

The watch will beep and reception will start. An indicator will appear on the display to indicate reception conditions.

To interrupt reception

Press the D button.

All other buttons besides D are disabled during signal reception.

When reception is successful
The watch terminates reception and adjusts the current time. Next it beeps and then displays the date and time that the adjustment was performed.

The watch will return to the Timekeeping Mode screen if you press the D button or if you do not perform any operation for about two or three minutes.

Reception Error (ERR Indicator)
The watch does not adjust its current time setting, and displays “ERR” when signal reception is unsuccessful for some reason.

The watch will return to the Timekeeping Mode screen if you press the D button or if you do not perform any operation for about two or three minutes.

Receive Indicator

The receive indicator cycles from “Unstable” through “Stable” as shown below while reception is in progress. How far it cycles depends on the signal strength. Keep the watch in a location where reception is stable while reception is in progress.

• Even under optimum reception conditions, it can take about 10 seconds for reception to stabilize.
• Use the receive indicator to check reception status and to determine the best location for signal reception.
• Note that weather, the time of day, surroundings, and other factors can all affect reception.

To view the last reception date and time

In the Timekeeping Mode, press the D button.

• This causes the display to start alternating between the last reception date screen and the last reception time screen at two-second intervals.
• “– – –” will appear in the digital display if the watch has not been able to perform any signal reception successfully.
• To return to the Timekeeping Mode, press the D button again. The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about two or three minutes.

Configuring Auto Receive Settings
Use the procedure below to turn auto receive of the time calibration signal on or off. When TYO (Tokyo) or SEL (Seoul) is selected as your Home City, you can also specify the transmitter selection mode, which controls which Japanese transmitter signal should be used for time calibration.

• For information about selecting your Home City, see “Configuring Home Time Settings”.

• The initial factory default settings for auto receive are Home City .
  TYO (Tokyo); Auto Receive = On; Transmitter = AUTO

• The following procedure can be performed only when TYO, SEL, NYC, CHI, DEN, or LAX is selected as the Home City.

To configure auto receive settings

1. In the Timekeeping Mode, press the D button.
   This causes the display to start alternating between the last reception date and time screens.
   The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about two or three minutes.

2. Hold down the AAAAA button for about two seconds.
   This will cause the current auto receive setting to flash on the display.

3. Use the D and B buttons to cycle through the available auto receive settings.
4. When the setting is the way you want, press the A button.
   • This will exit the setting screen and return to the last reception date and time screens.
   • To return to the Timekeeping Mode, press the D button again.
   • The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about two or three minutes.

Calibration Signal Reception Precautions

• Auto reception can be performed while the watch is in the Timekeeping Mode or World Time Mode only.

• Reception cannot be performed while Timer Mode countdown is in progress.

• Pressing any button while auto reception is in progress will cause the watch to beep and then exit the receive operation.

• Make sure you are within the range of the calibration signal transmitter before performing the reception operation. Remember that geographic contours, nearby buildings, seasonal conditions, the time of day, can even make reception impossible even when you are within range of the transmitter.

• Proper reception may be impossible if there is something blocking the signal. If reception is unsuccessful, try again.

• This watch is designed to adjust its current time setting in accordance with the calibration signal transmitted in Japan and the United States only. It operates like a standard (non-radio controlled) watch outside of the range of the receivable time calibration signal transmitters.

• When the watch is unable to adjust its time signal using the calibration signal for some reason, timekeeping accuracy is within
  ± 15 seconds per month.

• Strong electrostatic charge can cause timekeeping error.

• Signal reception is cancelled if the alarm starts to sound while it is being performed.

• The watch’s calendar shows dates up to the year 2099. Attempting a receive operation after that causes an error.

Troubleshooting

The watch cannot receive the time calibration signal.

• Is the signal being transmitted?
  Though the Japanese calibration signal (Call Sign: JJY) is continually transmitted by the National Institute of Information and Communications Technology (NICT) in theory, it may sometimes be interrupted for periodic maintenance work, or because of lightning or other problems.

• Are you within the reception range of a transmitter?
  See “Reception Range” for information about areas where the watch can receive the signal.
  Is there something in the immediate area that may be interfering with reception?
  Even if you are within the reception range of a transmitter, objects between you and the transmitter or electrical noise can interfere with reception. Avoid such areas during signal reception. See
  “Location” for more information.

• Do you have the correct Home City code selected?
  Remember that auto receive is not performed unless TYO
  (Tokyo), SEL (Seoul) NYC (New York), CHI (Chicago), DEN
  (Denver), or LAX (Los Angeles) is selected as the Home City. Select the correct Home City code using the procedure under “Configuring Home Time Settings”.

• Is auto receive turned off (OFF)?
  Use the procedure under “Configuring Auto Receive Settings” to turn on auto receive.

• Is the watch in any mode other than the Timekeeping Mode or World Time Mode during the auto receive times (midnight, 1:00 a. m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m.)?
  Auto receive is performed only when the watch is in the Timekeeping Mode or World Time Mode. It is not performed if the watch is in any other mode.

• Time calibration signal reception is successful, but the hourly time signal and current time are slightly off.
  After the watch receives the time calibration signal, it performs an internal decoding process before updating its time setting. Because of this, the time setting may be slightly off (within one second).

• Time calibration signal reception is successful, but the current time is one hour fast.
  Do you have summer time (DST) turned on (ON)? Use the procedure under “Configuring Home Time Settings” to turn off summer time.

• Time calibration signal reception is successful, but the current time setting is wrong.

• Is the correct city code selected for your Home City?
  If you are in Japan, you should have TYO selected for your Home City. For other areas, select the correct Home City code using the procedure under “Configuring Home Time Settings”.

• The auto receive ON/OFF settings don’t appear when configuring auto receive settings.
  Auto receive ON/OFF settings do not appear on the display unless TYO (Tokyo), SEL (Seoul), NYC (New York), CHI
  (Chicago), DEN (Denver), or LAX (Los Angeles) is selected as the Home City. Use the procedure under “Configuring Home Time Settings” to select your correct Home City.

• The auto receive AUTO, J40, and J60 settings do not appear when configuring auto receive settings.
  The AT, J40, and J60 transmitter selection mode options are available only when TYO (Tokyo) is selected as the Home City code. Use the procedure under “Configuring Home Time Settings” to select your correct Home City.

• What time is auto receive performed?
  Auto receive is performed in the middle of the night, when reception conditions are best. Before going to bed at night, place the watch near a window, with its 12 o’clock position facing in the general direction of the transmitter.

• How can I perform manual receive?
  Hold down the lower right D button for about two seconds. The watch will beep to indicate that manual receive has started. Place it near a window, with its 12 o’clock position facing in the general direction of the transmitter.

• How can I view the last reception date and time?

  • In the Timekeeping Mode, press the lower right D button. This will display the date and time that the time calibration signal was last received successfully. To return to the Timekeeping Mode, press the D button again. See “To view the last reception date and time” for more information.
  • Check the auto signal reception setting whenever you have problems with signal reception or when the time setting produced by signal reception is incorrect.
  • The initial factory default configuration of the reception settings are shown below. You do not need to change these settings if you use the watch in Japan.

World Time Mode

World time lets you display the current time in any one of 30 cities (29 time zones) around the world.

• When you enter the World Time Mode, the screen for the city that was displayed when you last exited the mode appears first.
• The seconds count in the World Time Mode is linked with the Timekeeping Mode seconds count.
• The same 12-hour/24-hour format you select for the Timekeeping Mode time is also applied in the World Time Mode.

Important!

• If the World Time Mode time is incorrect, check the current time settings in the Timekeeping Mode and the World Time city settings.
• For more information, see “Configuring Home Time Settings”.

To search for a city code
In the World Time Mode, press the D (westward) or B (eastward) button.

• This scrolls the available city codes.
• Holding down the B and D buttons scrolls at high speed.

Using Summer Time (DST)
