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.

❚

Checking the Battery Level

Use the Battery Level Screen to check the current level of the watch’s rechargeable battery.

• In the Timekeeping Mode, press the C button once to change to the Battery Level Screen. To return to the Timekeeping Mode from the Battery Level Screen, press the C button five times.

• Exposing the watch to direct sunlight or other strong light may cause the battery level indicator to momentarily indicate a level 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.

• When the battery level approaches Level 3, the display will start to flash and the analog hands will move to the 12 o’clock position.

• 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 digital time and date settings only. The analog hands will start to operate when the battery reaches Level 2. At that time, adjust the analog hand setting so it matches the digital time.

• When charging the battery, keep the watch exposed to light until the battery reaches Level 2 or Level 1.

Normal operation enabled.

Digital displays, face illumination, tones (alarm, hourly time signal), time calibration signal reception, and analog timekeeping disabled.

Face Illumination

An LED light is used to illuminate the face of the watch for easy reading in the dark. An auto light switch automatically illuminates the face when you angle the watch towards your eyes for reading.

❚

To illuminate the face manually

Press the

B button in any

mode to illuminate the face of the watch.

• You can use the procedure under

“To specify the illumination duration” to configure the illumination duration as approximately 1.5 seconds or 3 seconds.

• Pressing the B button illuminates the face 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 face with the auto light switch

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

• The auto light switch does not illuminate the face when surrounding light is bright.

You can use the procedure under “To specify the illumination duration” to configure the illumination duration as approximately 1.5 seconds or 3 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 B button for about two seconds to toggle the auto light switch on (auto light switch on indicator displayed) and off (no indicator displayed).

Power Saving

Power Saving causes the watch to automatically enter a sleep state 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.

• The watch will not enter the sleep state if it is in the Stopwatch Mode.

❚

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 times 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. Even when the watch is in the sleep state, digital-analog time coordination and time calibration signal auto receive are both performed.

Function sleep state

The function sleep state is triggered whenever the watch is left in the dark for six or seven days.

• The alarm and the hourly time signal are disabled while the watch is in the function sleep state. In the function sleep state, the analog hands remain stopped at the 12 o’clock position, and time calibration signal auto receive is not performed.

• Digital timekeeping functions continue to operate normally in the function sleep state.

❚

Positioning Your Arm Correctly

With the watch on your wrist, position it level with the ground.

• 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 the B button or if an alarm operation starts while the face is illuminated, illumination will turn off.

• Face illumination does not work while you are performing a time calibration signal manual receive operation.

Rotate your arm so the watch is angled at about 40 degrees, so you can read its face.

At least 40 degrees

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 “Positioning Your Arm Correctly”).

• 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 “To configure 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.

Auto Light Precautions

• Frequent use of the auto light can run down the battery.

• The auto light switch may cause the face to illuminate when your

sleeve covers the face of the watch.

• The face may not illuminate immediately when you angle the watch towards your face. This does not indicate malfunction.

• The face remains illuminated for the currently set duration (1.5 or 3 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 lower.

• The face 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 face 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.

• The auto light switch is automatically disabled when the watch is in the Hand Setting Mode.

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”.

(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, 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.

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.

Signal is received using built-in antenna.

Watch decodes received data and converts it to time data.

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

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.

Near high-voltage lines

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 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 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, 1:00, 2:00, 3:00 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.

• 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.
