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.
•
The special rechargeable (secondary) battery used by your watch is not intended to
be removed or replaced by you. Use of a rechargeable battery other than the special
one specified for this watch can damage the watch.
•
The current time and all other settings return to their initial factory defaults whenever
the watch is left uncharged for about one week after 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.
