Power Saving

Power saving causes the watch to automatically enter a sleep state to 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 its face is blocked from light by your sleeve.

❚

How the sleep state works

There are actually two sleep state levels, a “display sleep state” and a “function sleep state”.

• 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.

• Alarms 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 display sleep state, analog time timekeeping and auto signal receive are both performed.

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

• Function sleep state

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

• Alarms and the Hourly Time Signal are also disabled while the watch is in the function sleep state. Analog time timekeeping and auto signal receive are not performed while the watch is in the function sleep state.

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

❚

To recover from the sleep mode

Place the watch in an area that is well-lit, press any button, or angle the watch towards your face to illuminate the display using the auto light.

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

❚

To turn power saving on and off

See the procedure under “Manually Setting the Time and Date”.

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

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 in the top dial, and the following operations become disabled as battery power recovers.

• Illumination

• Alarm and Hourly Time Signal

• Time calibration signal reception

Normal operation will return after the battery recovers.

RECOVER Indicator

Illumination

An LED is used to illuminate the display for easy reading in the dark. An auto light switch automatically turns on illumination when you angle the watch towards your face for reading.

Illuminating the Display Manually

Press the

L button in any

mode to illuminate the display.

• You can use the procedure under “Specifying the Illumination Duration” to configure the illumination duration as approximately 1.5 seconds or 2.5 seconds.

• 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.

Level

• 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.

• Even if the battery level drops all the way to Level 4, you will still be able to recharge the battery and use the watch again.

• When recharging from Level 4, set the current time and date after the battery level recharges to Level 3. At this time you should continue to expose the watch to light so it can charge up to 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 battery level indicator shows Level 3.

Illuminating the Display with the Auto Light Switch

The auto light switch automatically illuminates the display whenever you angle the watch towards your face for reading, but only when it is dark. You can use the procedure under “Specifying the Illumination Duration” to configure the illumination duration as approximately 1.5 seconds or 2.5 seconds.

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

The auto light switch illuminates the display in all modes.

Turning the Auto Light Switch On and Off

In any mode, hold down the L button for about two seconds to toggle the auto light switch on (auto light switch on indicator displayed in the upper dial) and off (no indicator displayed).

Charging Precautions

Avoid charging the watch in the following locations, and anywhere else 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.

❚

Charging the Battery

Point the solar panel (face) of the watch at a light source.

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

Example: Positioning the watch

• The illustration shows the resin band model.

❚

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 L button or if an alarm operation starts while the display is illuminated, illumination will turn off.

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

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 lit for the currently set illumination 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 lower.

• 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 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.

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 using

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.

built-in antenna.

Decode

Watch decodes received data and converts it to time data.

Time is adjusted according to time data.

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.

Though the calibration signal is normally transmitted 24 hours a day, transmission may be interrupted occasionally due to maintenance, lightening, 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 “Manually Setting the Time and Date”. For information about city codes, see the “City Code List”.
