Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to read this manual carefully.
Keep the watch exposed to bright light
The electricity generated by the solar panel of the watch is
stored by a rechargeable battery. Leaving or using the
watch where it is not exposed to light causes the battery
to run down. Make sure the watch is exposed to light as
much as possible.
• When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
• You should try to keep the watch outside of your sleeve
as much as possible. Charging is reduced signifi cantly
if the face is covered only partially.

• The watch continues to operate, even when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will result in some
watch functions to be disabled. If the battery goes dead, you will have to
re-confi gure watch settings after recharging. To ensure normal watch operation, be
sure to keep it exposed to light as much as possible.
