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” for important information you need to know when exposing the watch to bright light.

If the digital display of the watch is blank...

If the Power Saving on indicator (PS) is on the display (either flashing or not flashing), 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 enters a sleep state whenever your watch is left for a certain period where it is dark. If the watch is kept in the dark for a longer period, the analog hands will also stop moving after a few days.

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.

See “Power Saving Function” for more information.
