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 time zone that corresponds to the Greenwich
Mean Time differential of –3.5 hours. Because of this, the radio-controlled
timekeeping function will not display the correct time for Newfoundland,
Canada.
General Guide
• Press C to change from mode to mode.
• In any mode (except when a setting screen is on the display), press A to illuminate
the face of the watch.
Timekeeping Mode
Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
The time calibration signal includes both Standard Time and Daylight Saving Time
(summer time) data.
• This watch is designed to pick up the time calibration signal transmitted from Fort
Collins, Colorado (USA). Reception is possible within North America*.
* The term "North America" in this User's Guide refers to the area that consists of
Canada, the continental United States, and Mexico.
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 will normally use the watch. For more
information, see "To specify your Home Time Zone" below.
• When using the watch outside the range of the time signal transmitter, you will have
to adjust the current time setting manually as required. See "Timekeeping" for more
information about manual time settings.

• The watch will also return to the Timekeeping Mode if you do not perform any
operation for two or three minutes.
• Your watch should show the correct time when you exit the Home Time Zone setting
screen. While the hands are moving to the new time setting, the current time will be
shown on the digital display. 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.
• Even if the time calibration signal is received correctly, there are some times when
the analog hands may not indicate the correct time. If this happens, use the
procedures under "Adjusting the Home Positions" to check the home positions of the
hands, and make adjustments as required.
• See the map under "Reception Range" for information about the reception range of
the watch.
• You can disable time signal reception, if you want. See "To set the time and date
manually" for more information.
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".

will cause the analog hands to move to the current time
setting.

you do not perform any button operations or move the watch during this time.
Reception Range
600 miles
• At distances further than about 600 miles (1,000 kilometers) from the transmitter,
signal reception may not be possible during certain times of year or times of day.
Radio interferance may also cause problems with reception.
• Even when the watch is within the reception range of the transmitter, signal
reception is impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
• See the information under "Signal Reception Troubleshooting" if you experience
problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 0:00 a.m., 1:00 a.m.,
2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also
perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto
receive operations are successful.
When any auto receive is successful, the remaining auto receive operations are not
performed.
