Battery

This watch is equipped with a solar cell and a 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 pointing at a light source. Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc. The illustration shows how to position a watch with a resin band. 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 bright light can cause rechargeable battery power to run down. Be sure that the watch is normally exposed to bright light whenever possible. This watch employs a solar cell that converts light into electricity, which charges a built-in rechargeable battery. Normally, the rechargeable battery should not need replacement, but after very long use over a number of years, the rechargeable battery may lose its ability to achieve a full charge. Should you notice problems with getting the rechargeable battery to a full charge, contact your dealer or CASIO distributor about having the rechargeable battery replaced. The rechargeable battery should be replaced with a CASIO-specified ML2016 battery only. Other rechargeable batteries can cause damage to the watch. All data stored in memory is deleted, and 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 watchs 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.

Auto Display

Auto Display continually changes the contents of the digital display.

The flashing charge (C) indicator at Level 4 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, 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, date, and all other settings after the battery is recharged to Level 3 from Level 5. Though the time appears on the display after the battery is charged to Level 4 (indicated by flashing charge (C) indicator), you will not be able to change the time, date, and all other settings until the battery reaches Level 3 (no charge (C) indicator). Leaving the watch in direct sunlight or some other very strong light source can cause the battery power indicator to temporarily show a reading that is higher than the actual battery level. The correct battery power indicator should appear after a few minutes. If you use the backlight or any of the alarm functions a number of times during a short period, the recover (R) indicator appears on the display and the following operations become disabled until battery power recovers. Backlight; Beeper tone After some time, battery power will recover and the recover (R) indicator will disappear, indicating that the above functions are enabled again.

Auto return features

After you perform any button operation (except for the backlight button) in any mode, pressing C returns directly to the Timekeeping Mode. If you leave the watch in the Data Bank, Alarm, and Day Counter Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode. If you leave a screen with flashing digits or a cursor on the display for two or three minutes without performing any operation, the watch automatically saves any settings you have made up to that point and exits the setting screen.

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.
