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 and keep it on hand for later reference
when necessary.
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. Even if the face of the watch is
only partially blocked from light, charging will be reduced
significantly.

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.

Be sure to read “Power Supply” for important information you need to know
when exposing the watch to bright light.

If the analog hands aren’t moving, it means that the power saving mode has stopped
them to save battery power.

See “Power Saving” for more information.

The hands also stop whenever the battery level reaches Level 3.

Radio-controlled 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 in Germany
(Mainflingen) and England (Rugby).
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 Germany and England time signal
transmitters, you have to adjust the current time setting manually as required. See
“Timekeeping” for more information about manual time settings.
To specify your Home Time Zone
1. In the Timekeeping Mode, hold down
A
for about five
seconds until the second hand moves to the currently
selected GMT differential value and stops. This is the
setting mode.
•
The GMT differential value indicates the time
difference in hours between Greenwich Mean Time
and the currently selected time zone.
2. Press
B
to select the time zone you want to use as
your Home Time Zone.
GMT+ 0 (12 o’clock): London
GMT+ 1 (1 o’clock): Paris, Berlin, Milan, Rome,
Amsterdam, Hamburg, Frankfurt, Vienna,
Barcelona, Madrid
GMT+2 (2 o’clock): Athens
3. Press
A
eight times to exit the setting mode.
•
The watch will also return to the Timekeeping Mode if
you do not perform any operation for about two or three
minutes.

•
Normally, your watch should show the correct time as soon as you specify 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.
•
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.
•
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 (GMT differential values) and
transmitters, see “Transmitters”.
•
See the maps under “Reception Ranges” for information about the reception ranges
of the watch.
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”.
Important!
•
When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 9 o’clock side facing towards a window.
Make sure there are no metal objects nearby.
9 o’clock
or
•
The watch should not be facing the wrong way.
•
Proper signal reception can be difficult or even impossible under the conditions listed
below.
•
Signal reception is normally better at night than during the day.
•
Time calibration signal reception takes from two to seven minutes, but in some
cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.
