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 cell reduces

charging efficiency.

Example: Positioning the watch

Solar Cell

• The illustration shows the resin band model.

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.

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.

Power Saving

Indicator

❚

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.

❚

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 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.

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.

Rotate your arm so the watch

is angled at about 40 degrees,

so you can read its face.

With the watch on

your wrist, position it

level with the ground.

At least

degrees

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).

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.

Long-

wave time

calibration

signal

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 standard wave may be

interrupted occasionally due to maintenance, lightening, etc.

How a Radio-controlled Watch Works

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.

Near high-voltage lines

Among or near buildings

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.

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.

(construction site, airport, etc.)

Next to a household appliance or

office equipment (TV, speaker,

fax, computer, cell phone, 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”.
