Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging.

Example: Orient the watch so its face is	Solar cell

Adjusting the Home Positions

If the time and date settings are wrong even after the time calibration signal is received normally, use the following procedure to adjust their home positions.

To adjust the home positions

• The illustration shows how to position

a watch with a resin band.

• Note that charging efficiency drops

when any part of the solar cell is

blocked by clothing, etc.

•You should try to keep the watch outside of your sleeve as much as

possible. Even if the face of the watch is blocked from light only partially, charging will be reduced significantly.

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. Make 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

cell, 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 3 and when you have the battery replaced.

• Keep the watch in an area normally exposed to bright light when storing it for long

periods. This helps to keep the rechargeable battery from going dead.

Battery Power Levels

The movement of the analog hands indicates the current battery power level.

3	•Second hand stopped.	All functions disabled.
	•Hour and minute hands

Jumps 2 seconds

•The second hand jumping every two seconds (Level 2) indicates that battery power is quite low. Expose the watch to light as soon as possible to charge the battery.

•When battery power is at Level 2, time calibration signal reception is disabled.

•At Level 3, all functions are disabled and settings return to their initial factory defaults. The analog hands will move to the current time and normal timekeeping will resume when the battery is recharged sufficiently.

•Alarm operation can cause hand movement to stop due to the sudden temporary drop in battery power. This does not indicate malfunction, and normal operation will resume when the watch is exposed to light. Though hand movement stops, timekeeping continues internally, and the hands will be adjusted to the correct setting when normal operation returns.
