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 normally 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.
