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

Keep the watch exposed to bright light
The electricity generated by the solar cell of the watch is stored by a built-in
Bright Light
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.
Solar cell
• You should try to keep the watch outside of your sleeve as much as
possible. Charging is reduced significantly if the face is even only partially
covered.
• 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.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.
• This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen),
England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/
Saga).
•
See the information under "Signal Reception Troubleshooting" if you experience problems with time
calibration signal reception.
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration signal. You also can
perform a manual procedure to set the time and date, when necessary.
• The first thing you should do after purchasing this watch is to specify your Home City (the city
where you normally will use the watch). For more information, see "To specify your Home City".
• When using the watch outside the areas covered by the time signal transmitters, you will have to
adjust the current time setting manually as required. See "To set the time and date manually" for more
information about manual time settings.
• The North American time calibration signal can be picked up by the watch while in North America. The
term "North America" in this manual refers to the area that consists of Canada, the continental United
States, and Mexico.
• Using this watch in a country covered by a time calibration signal that is different from the countries it
supports may result in incorrect time indication due to local application of summer time, etc.
