Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to read this manual carefully.

The electricity generated by the solar cell 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 significantly 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-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.
