Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to carefully read this manual and keep it on hand for later reference
when necessary.
Expose the watch to bright light to charge its battery before using it.
You can use this watch even as its battery is being charged by exposure to bright
light.
• Be sure to read “Battery” of this manual for important information you
need to know when exposing the watch to bright light.
If the display of the watch is blank...
If the SLEEP indicator is on the display, it means that the
display is blank because the watch’s Power Saving
function has turned off the display to conserve power.
Power Saving automatically turns off the display and puts
the watch into a sleep state whenever your watch is left for
a certain period where it is dark.
• The initial factory default setting is Power Saving on.
• The watch recovers from the sleep state if you move it to
a well-lit area*, if you press any button, or if you angle
the watch towards your face for reading.
*
It can take up to five seconds for the display to turn on.
