This watch has a rechargeable cell which is charged by exposing the dial to light, such

as direct sunlight or fluorescent lamps (refer to pages 14 and 15 for charging

guidelines).

After taking off the watch, put it in a location where the dial is exposed to bright light,

such as by a window.

For optimal performance, be sure to:

• Thiswatchcontainsalargecapacitybattery

for performing power-consuming satellite

signal reception. This battery takes some time

until it is fully charged.

• Chargethewatchbyexposingittodirect

sunlight for five to six hours at least once

every two weeks.

• Avoidleavingthewatchinadarkplacefor

long periods of time.

Charging your watch

13

English

• If the watch is obscured from light by long sleeves frequently, supplemental

charging may be needed to ensure continual operation.

• Do not charge the watch at a high temperature (about 60°C (140°F) or higher) as

doing so may cause movement malfunction.

• If the surrounding temperature falls below 0°C (32°F) or exceeds 40°C (104°F), the

“Charge suspension temperature detection function” will activate and charging will

not be possible.

Charging your watch

 When the watch reaches a low charge state (insufficient charge

warning function)

When the power reserve becomes low, the second hand moves once every two

seconds. This is the insufficient charge warning function. Be sure to fully charge

your watch.

• Whenthewatchissufficientlycharged,thesecondhandwillmovenormally.

• Ifyoudonotchargethewatchfor10daysorlongeraftertheinsufficientcharge

warning movement has begun, the watch

will be depleted of all power and stop.

Even when the second hand moves once

every two seconds, the current time and

date are indicated, and you can adjust

the time and date. However, satellite

time signal reception and other

operations are not possible.

• To charge the rechargeable cell, it is recommended to expose the dial to

direct sunlight. A fluorescent lamp or interior lighting does not have sufficient

illumination to charge the rechargeable cell.

•

When the battery is fully charged, the overcharge protection function stops the charging so

that the watch performance and rechargeable cell are not adversely affected by overcharge.

Caution: This watch uses a special rechargeable cell.

• If the surrounding temperature falls below 0°C (32°F) or exceeds 40°C (104°F), the

“Charge suspension temperature detection function” will activate and charging will

not be possible.

• If you do not charge the watch for 60 days after it has stopped, the “Over discharge

detection function” will activate and charging will not be possible.

If the watch does not work even after charging for more than one day under direct

sunlight, please consult Citizen Customer Support Center.

Charging your watch

• When the power reserve is at the 0 level, the second hand indicates the insufficient

charge warning state (by moving once every two seconds). You can manually correct

the time and calendar, but you cannot perform the other operations and receive

satellite signals.

• When the watch temperature is too high or too low or

when the watch is not sufficiently charged due to low

illuminance, the function indication hand makes one

clockwise turn to indicate the day of the week without

indicating the charge level during checking the power

reserve. Place the watch in a bright location at a

moderate temperature to charge it.
