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.
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 “Power Supply” of this manual for important information you
need to know when exposing the watch to bright light.
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.

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.
• Supported time calibration signals: Germany
(Mainflingen), England (Anthorn), United States (Fort
Collins), Japan.
Current Time Setting
This watch adjusts its time setting automatically in
accordance with a time calibration signal. You can also
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 Time Zone, which is the time
zone where you normally will use the watch. For more
information, see “To specify your Home Time Zone”.

• 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 “Timekeeping”
for more information about manual time settings.
• The U.S. 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.
• The analog time of this watch is synchronized with the digital time. Because of this,
the analog time setting is automatically adjusted whenever you change the digital
setting. See “Analog Timekeeping” for more information.
To specify your Home Time Zone
1. In the Timekeeping Mode, hold down A the UTC
differential value starts to flash, which indicates the
setting screen.
• Though illumination will also turn on when you press
A, keep the button held down until UTC differential
value flashes.
2. Press C to select the time zone you want to use as
your Home Time Zone.
• Time calibration signal reception is supported when

Important!
• Normally, your watch should show the correct time as soon as you select your Home
Time Zone. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You can also perform manual receive or you
can set the time manually.
• The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between time zones and transmitters, see “Home
Time Zones and Transmitters”.
• Under factory default settings, auto receive is turned off for all of the following time
zones : UTC +8, UTC –10, and UTC –9. For details about turning on auto receive for
these time zones, see “To turn auto receive on and off”.
• You can disable time signal reception, if you want. See “To turn auto receive on and
off” for more information.
• See the maps under “Approximate Reception Ranges” for information about the
reception ranges of the watch.
• 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 receives the time calibration signal automatically up to
six times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. 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”.
