Power Supply

The power supply of this watch uses a solar panel to generate electrical power, which is stored by a rechargeable battery. Using or storing the watch where it is not exposed to light regularly or allowing it to be blocked from light by your sleeve 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.

Note that all data in memory and all settings are cleared whenever you allow the level of the rechargeable battery to go dead.

Flashing RECOV Indicator

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

• Illumination

• Alarm and hourly time signal

• Time up beeper

• Time calibration signal reception

Normal operation will return after the battery recovers.

Low Battery Indication

When rechargeable battery power goes low, the watch will start to disable some of its functions and “LOW” will flash on the display in the Timekeeping Mode. If the dual time screen is displayed, the screen will change automatically to the home time screen. If you continue using the watch without charging the battery, more functions will become disabled and “CHG” will start to flash on the display. Be sure to recharge the battery by exposing the watch to light as soon as possible at the first sign of low battery power. Frequent flashing of the RECOV indicator also means that the battery is low. Expose the watch to light to charge the battery.

Display Indication Disabled Functions

Timekeeping Mode

• When the rechargeable battery goes completely dead, the display will go blank and timekeeping will stop. These functions will be restored when the battery is recharged.

• When you start to recharge the battery after it does dead, “CHG” will start flashing on the display. However, watch functions will not yet be re-enabled at this time. Keep the watch exposed to light until the flashing “CHG” indicator disappears from the display.

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 (face) of the watch at a light source.

• Remember that even a partial blockage of the solar panel reduces charging efficiency.

Example: Positioning the watch

Power Saving causes the watch to enter a sleep state automatically in order to save power whenever it 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 p.m. and 6 a.m.

• The display sleep state causes the display to go blank, except for a flashing Power Saving indicator. Alarms and the hourly time signal continue to operate normally while the watch is in the display sleep state.

• The watch does not enter the sleep state if it is in the Timer Mode or Stopwatch Mode.

Power Saving Indicator

• 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, and the following functions are disabled. Alarms and the hourly time signal are also disabled while the watch is in the function sleep state. Time calibration signal reception is not performed while the watch is in the function sleep state.

• Digital timekeeping functions continue to operate normally.

To recover from the sleep state

Move the watch to a brightly lit location or press any button.

• 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

See the procedure under “To configure Home City settings” for information about turning off Power Saving.

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

In any mode (except when a setting screen is on the display), press the B button to illuminate the display for easy reading in the dark.

• Illumination may be difficult to see under bright sunlight.

• Illumination turns off automatically if an operation tone or alarm

sounds.

• Illumination will not turn on while manual receive is in progress.

• You may notice a slight sound from the watch while illumination is

turned on. This is the sound of EL panel vibration and does not indicate malfunction.

The tone that sounds to signal a mode change or other operation can be turned on and off.

❚

To turn the operation tone on or off

When any screen besides a setting screen (one with a flashing setting) is on the display, hold down the button for about three seconds.

• This will cause the operation tone to sound and then toggle the operation tone on or off.

• A MUTE indicator is on the display while the operation tone is off.

• Holding down the C button also changes the watch’s current mode.

• The alarm, hourly time signal, and timer time up beeper continue to sound, even when the operation tone is turned off.

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.

Transmitter

Cesium

atomic clock

After the watch receives the time calibration 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.

Long-wave time calibration signal

Watch

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.

Among or near buildings Near high-voltage lines Inside a vehicle

Next to a household appliance or office equipment (TV, speaker, fax, computer, cell phone, etc.)

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.

radio interference (construction site, airport, etc.)

Calibration Signal

• The Japanese calibration signal (Call Sign: JJY) is maintained by the National Institute of Information and Communications Technology (NICT). It is transmitted 24 hours a day from the Mt. Otakadoya transmitter (40 kHz) located in Tamura-gun, Fukushima Prefecture, and from the Mt. Hagane transmitter (60 kHz) 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 (NIST) from Fort Collins, Colorado.

• The U.K. calibration signal (Call Sign: MSF) is transmitted by the National Physical Laboratory (NPL) from Rugby, Warwickshire.

• The German calibration signal (Call Sign: DCF77) is transmitted by Physikalisch - Technische Bundesanstalt (PTB) from Mainflingen.

The time data of the Japanese calibration signal (Call Sign: JJY) is maintained by the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT). Note that transmission of the standard wave may be interrupted occasionally due to maintenance, lightning, etc. For more information, visit the website of the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT) at the following URL.

Receiving the Calibration Signal

There are two methods you can use in order to receive the time calibration signal.

• Auto Receive, six times a day: Midnight, 1:00, 2:00, 3:00, 4:00, and 5:00 a.m.

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

• Any time a signal receive operation is successful, no more auto receive operations are performed that day.

• 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.

Note however that auto receive is turned off for the following city codes: BJS, HKG, HNL, ANC, and MOW.

For information about turning auto receive on and off, see “To turn auto receive on and off”.

• Auto receive will be performed whenever the Timekeeping Mode (see “Modes and Indicators”) Home Time reaches one of the times shown above.

• The auto receive start time differs according to the current home city and summer time setting.
