Power Saving

Power Saving causes the watch to automatically enter a sleep state to save power whenever the watch is left in the dark.

• 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 watch enters the display sleep state, which causes the display to go blank. 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 Stopwatch Mode.

Power Saving

• The module number is engraved on the back cover of the watch case.

• 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. 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

in the function sleep state.

indicator

To recover from the sleep state

Place the watch in an area that is well-lit, press any button, or angle the watch toward your face to illuminate the display of the watch using the Auto Light.

• 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 Time and Date Settings Manually” to turn Power Saving on or off.

• Power Saving is designed to conserve power when you do not use the watch for a long time.

• To conserve power, the World Time that you can display on the Timekeeping Mode stops while the watch is in a sleep state. When the watch recovers from a sleep state, the Timekeeping Mode World Time restarts from the time that it stopped when the sleep state was entered. To correct the World Time, change to the World Time mode and then return to the Timekeeping Mode. Note that the Timekeeping Mode World Time will not stop if Power Saving is turned off.

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 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 drop to Level 4.

❚

Flashing Recover Indicator

If you use the light or alarms a number of times during a short period, a RECOVER 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.

Display Illumination

An EL (electro luminescent) 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 face for reading.

❚

To illuminate the display manually

When any screen besides a setting screen (one with a flashing setting), press the

B button to illuminate the

display of the watch.

• The display remains illuminated for about 1.5 seconds.

• Pressing the B 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.

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.

Signal is received

Transmitter

Cesium atomic clock

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.

Long-wave time calibration signal

Time is adjusted according to time data.

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 (automobile, train, plane, etc.)

In a location where there is radio interference (construction site, airport, 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.

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

Near mountains

Calibration Signal

• The Japanese calibration signal (Call Sign: JJY) is maintained by the independent Japan Ministry of Posts and Telecommunications Communication Research Laboratory (CRL). 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 standard wave may be interrupted occasionally due to maintenance, lightening, etc.

Receiving the Calibration Signal

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

• Auto receive (Reception is performed automatically at

midnight, 2:00, and 4:00 each morning.)

•

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

• If reception is not successful for any of the normal auto receive operations shown above, auto receive is performed one more time at 5:00 a.m.

• 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.

Resin band

Metal band

• 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.

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 “Selecting Your Home City”. For information about city codes, see the “World Time City Code List”.

(60kHz)

• Under optimum conditions, the calibration signal should be receivable up to 1,000 kilometers from the transmitter. Note that the wave is relatively weak at distances greater than 500km, so reception may be poor at long distances.

• Geographic contours, nearby buildings, the season, 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.

❚

Time Required for Reception

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

• Note that when “FREQ.A” (Auto Select) is specified as the transmitter selection mode, signal reception can take up to 12 minutes.

Calibration Signal Reception Precautions

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

• Operating 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, the season, 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. Note that you will need to make your own adjustments when using this watch outside of Japan or the United States, or in any area that is outside the range of one 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 an 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 independent Japan Ministry of Posts and Telecommunications Communication Research Laboratory (CRL) in theory, it may sometimes be interrupted for periodic maintenance work, or because of lightening 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 (Japan), 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 “Selecting Your Home City”.

• Is auto receive turned 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, 2:00 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? Use the procedure under “Configuring Summer Time (Daylight Saving 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 “Selecting Your Home City”.

Alarm Mode

Your watch comes with five alarms and an hourly time signal.

• Daily Alarms (AL 1 to AL 4)

The watch beeps for about 10 seconds when an alarm time is reached.

• Snooze Alarm (SNZ)

With the snooze alarm, the watch beeps for 10 seconds when the alarm time is reached, and up to seven times at five-minute intervals thereafter (approximately 30 minutes total). Pressing any button stops the beeper, but the alarm will sound again after five minutes.

• Hourly Time Signal

The hourly time signal causes the watch to beep twice every hour on the hour.

When you enter the Alarm Mode, the screen for the alarm that was displayed when you last exited the mode appears first.
