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.
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.
If the digital display of the watch is blank...
If the digital display of the watch is blank, it means that the
watch’s Power Saving function has turned it off to
conserve power.
Power Saving automatically turns off the display and
enters a sleep state whenever the watch is left for a
certain period where it is dark.
• The initial factory default setting is Power Saving on.
• The watch will recover from the sleep state if you move it
to a well-lit area,
*
if you press any button, or if you angle
the watch towards your face for reading.
*
It can take up to two seconds for the display to turn on.
• See “Power Saving” for more information.

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 automatically adjusts its digital time setting 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.
• The analog time of this watch is synchronized with the digital time. Because of this,
the analog time setting is adjusted automatically 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 until the GMT
differential value starts to flash, which indicates the
setting screen.
• The second hand will move at high speed to the 12
o’clock position, where it will stop.
• The GMT differential value indicates the time
difference in hours between Greenwich Mean Time
and the currently selected time zone.
• The DST indicator indicates that Daylight Saving Time
(summer time) is turned on for the currently selected
time zone.

2. Use D (+) and B (–) to select the time zone you want to use as your Home Time
Zone.
• The GMT differential values for major cities in the Western Europe time zones are
shown below. Note that if the time zone you selected is in Daylight Saving Time
and the signal receiving indicator (
) is on the display (indicating that the watch
has received a signal and has adjusted its GMT differentials for Daylight Saving
Time), you must select the GMT differential values shown in the parentheses.
+ 1.0 (DST + 2.0):Paris, Berlin, Milan, Rome, Amsterdam, Hamburg, Frankfurt,
Vienna, Barcelona, Madrid
+ 0.0 (DST + 1.0):London
3. Press A to exit the setting screen.
• The second hand will advance at high speed to the correct position in accordance
with the seconds count of the digital time, and resume normal movement from there.
• 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.
• Selecting +1.0 or +0.0 as your Home Time Zone automatically turns on auto receive.
When auto receive is turned on and you are within the reception range, the watch
will automatically receive the time calibration signal 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.
• If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting.
• If A, D77.5, M60, or OFF starts to flash in place of the GMT differential value when
you hold down A in step 1 of the above procedure, press A again to exit the
setting screen. After that, press B and then perform step 1 again.
To display the digital time and last signal screen
• In the Timekeeping Mode, press A to cycle through the digital time screens as
shown below.
• In the Timekeeping Mode, press B to display the last signal screen. The last signal
screen shows the date and time of the last successful time calibration signal
reception.

Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive
and
manual receive
. The second hand stops at the 12 o’clock position
while time calibration signal reception is in progress. After reception is complete, the
second hand moves automatically until it matches the digital time.
• Auto Receive
With auto receive, the watch automatically picks up the time calibration signal five
times a day at 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 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.
• The watch should not be on its side or facing the wrong way.
