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 | Solar cell |
is pointing at a light source. |
|
• 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. Charging is reduced significantly if the face is only partially covered.
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 5 and when you have the battery replaced.
•Turn on the watch’s Power Saving function 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.
Battery Power Indicator and Charge Indicator
The battery power indicator shows you the current power level of the rechargeable battery.

•The 
at Level 3 and the flashing charge indicator (CHG) at Level 4 tell you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.
•At Level 5, all functions are disabled and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date, after the battery reaches Level 4 (indicated by the flashing charge indicator (CHG)) from Level 5. You will not be able to configure any of the other settings until the battery reaches Level 3 (no charge indicator) after dropping to Level 5.
•Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to show a reading that is momentarily higher than the actual battery level. The correct battery power indicator should appear after a few minutes.
•If you use the illumination or alarms a number of times during a short period, the charge indicator (CHG) flashes and the following operations become disabled until battery power recovers.
Illumination Beeper tone
Time calibration signal reception
After some time, battery power will recover and the charge indicator (CHG) will disappear, indicating that the above functions are enabled again.
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
Charging Guide
After a full charge, timekeeping remains enabled for up to about nine 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) | 5 minutes |
|
|
Sunlight Through a Window (10,000 lux) | 24 minutes |
|
|
Daylight Through a Window on a Cloudy Day | 48 minutes |
(5,000 lux) |
|
|
|
Indoor Fluorescent Lighting (500 lux) | 8 hours |
|
|
•For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications.
•Stable operation is promoted by frequent exposure to light.
Recovery Times
