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 Solar cell face is pointing at a light source.
Stopwatch
The stopwatch lets you measure elapsed time, split times, and two finishes. � The display range of the stopwatch is 99 hours, 59 minutes, 59.99 seconds. � The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it. � The stopwatch measurement operation continues even if you exit the Stopwatch Mode. � Exiting the Stopwatch Mode while a split time is frozen on the display clears the split time and returns to elapsed time measurement. � All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C.
� 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 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 CTL1616 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 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.
