Important!

• Storing the watch for long periods in an area where there is no light or wearing it in

such a way that it is blocked from exposure to light can cause rechargeable battery

power to run down. Be sure that the watch is exposed to bright light whenever

possible.

• This watch uses a special rechargeable battery to store power produced by the

solar panel, so regular battery replacement is not required. However, after very

long use, the rechargeable battery may lose its ability to achieve a full charge. If

you experience problems getting the special rechargeable battery to charge fully,

contact your dealer or CASIO distributor about having it replaced.

• Never try to remove or replace the watch’s special battery yourself. Use of the

wrong type of battery can damage the watch.

• The current time and all other settings return to their initial factory defaults whenever

battery power drops to Level 5 (

CHG

) (page E-51) and when you have the battery

replaced.

• Turn on the watch’s Power Saving function (page E-68) and keep it in an area

normally exposed to bright light when storing it for long periods. This helps to keep

the rechargeable battery from going dead.

The battery power indicator indicates you the current status of the rechargeable

battery’s power.

• The fl ashing

LOW

indicator at Level 3 (

L

) tells you that battery power is very low,

and that exposure to bright light for charging is required as soon as possible.

• At Level 5 (

CHG

), all functions are disabled and settings return to their initial factory

defaults. Once the battery reaches Level 2 (

M

) after falling to Level 5 (

CHG

),

reconfi gure the current time, date, and other settings.

• Display indicators reappear as soon as the battery is charged from Level 5 (

CHG

)

to Level 2 (

M

).

• The watch’s Home City code setting will change automatically to

TYO

(Tokyo)

whenever the battery drops to Level 5 (

CHG

). With this Home City code setting, the

watch is confi gured to receive the time calibration signals of Japan. If you are using

the watch in North America or Europe, or China you will need to change the Home

City code setting to match your location whenever the battery drops to Level 5

(

CHG

).

• Leaving the watch exposed to direct sunlight or some other very strong light source

can cause the battery power indicator to show a reading temporarily that is higher

than the actual battery level. The correct battery level should be indicated after a

few minutes.

E-53

• Overuse of display illumination or the beeper can

cause the

R

(Recover) indicator to appear in the upper

display, which indicates that the watch is in the battery

power recovery mode. Face illumination, the alarm, the

countdown timer alarm, time signals, and all hand

operations are disabled in the power recovery mode.

The watch continues to keep time internally, so regular

timekeeping and function will resume as soon as

battery power recovers to normal levels, which is

indicated when the

R

indicator disappears.

• If

R

appears frequently, it probably means that

remaining battery power is low. Leave the watch in

bright light for some time to allow it to charge.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid leaving

the watch in the areas described below whenever charging its rechargeable battery.

Also note that allowing the watch to become very hot can cause its liquid crystal

display to black out. The appearance of the LCD should become normal again when

the watch returns to a lower temperature.

Warning!

Leaving the watch in bright light to charge its rechargeable battery can cause it

to become quite hot. Take care when handling the watch to avoid burn injury.

The watch can become particularly hot when exposed to the following

conditions for long periods.

• On the dashboard of a car parked in direct sunlight

• Too close to an incandescent lamp

• Under direct sunlight

E-55

Charging Guide

After a full charge, timekeeping remains enabled for up to about six months.

• The following table shows the amount of time the watch needs to be exposed to

light each day in order to generate enough power for normal daily operations.

Exposure Level (Brightness) Approximate

Exposure Time

Outdoor sunlight (50,000 lux) 8 minutes

Sunlight through a window (10,000 lux) 30 minutes

Daylight through a window on a cloudy day (5,000 lux) 48 minutes

Indoor fl uorescent lighting (500 lux) 8 hours

• For details about the battery operating time and daily operating conditions, see the

“Power Supply” section of the Specifi cations (page E-77).

• Stable operation is promoted by frequent exposure to light.

E-56
