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 cell of the watch is
stored by a built-in 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 significantly if
the face is 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 cause 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.

Important!
• Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You also can perform manual receive or you
can set the time manually.
• If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch picks up the time calibration signal automatically six
times a day at midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m.
For more information, see “About Auto Receive”.
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive”.
Important!
• When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side facing towards a window.
Make sure there are no metal objects nearby.
