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.

 Be sure to read “Power Supply” (page E-40) for important information you 

need to know when exposing the watch to bright light.

If the display of the watch is blank, it means that the watch’s Power Saving function 
has turned off the display to conserve power.
