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.

This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.

Keep the watch exposed to bright light

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.

The actual level at which some functions are disabled depends on the watch model.

Frequent display illumination can run down the battery quickly and require charging. The following guidelines give an idea of the charging time required to recover from a single illumination operation.

Approximately 5 minutes exposure to bright sunlight coming in through a window Approximately about 8 hours exposure to indoor fluorescent lighting

Be sure to read “Power Supply” (page E-45) for important information you need to know when exposing the watch to bright light.

If the display of the watch is blank...

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.

See “Power Saving Function” (page E-69) for more information.
