Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to carefully read this manual 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 “Battery” of this manual for important information you need to
know when exposing the watch to bright light.
About This Manual
•
Button operations are indicated using the letters shown
in the illustration.
•
Each section of this manual provides you with the
information you need to perform operations in each
mode. Further details and technical information can be
found in the “Reference” section.
If the digital display of the watch is blank...
If the Power Saving indicator (
PS
) is flashing on the display,
it means that the display is blank because the watch’s
Power Saving function has turned off the display to
conserve power. Power Saving automatically turns off the
display and enters a sleep state whenever your watch is
left for a certain period where it is dark. If the watch is kept
in the dark for a longer period, the analog hands will also
stop moving after a few days.
•
The initial factory default setting is Power Saving on.
•
The watch recovers 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.
•
See “Power Saving Function” for more information.

Radio-controlled Timekeeping
This watch is designed to pick up a time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt), and update its time
setting accordingly. The time calibration signal includes
both Standard Time and Daylight Saving Time (summer
time) data.
Current Time Setting
This watch automatically adjusts its 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 set your Home City, which is the city where you will
normally use the watch. For more information, see “To
set your Home City” below.

•
The second hand will advance at high speed to the
correct position in accordance with seconds count of the
digital time, and resume normal movement from there.
•
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 can also
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 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!
•
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.

•
This watch is able to receive the time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt). Signal reception is
possible within the area represented by a circle with a
radius of about 1,000 kilometers.
•
At distances further than about 500 kilometers, the
signal may become weak and reception may be
impossible under certain conditions.
•
Signal reception may be poor in the shaded area on the
map, even though it is within 1,000 kilometers of the
signal transmitter.
•
See the information under “Signal Receive
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 operation at 5:00 a.m. if none of regularly
scheduled auto receive operations are successful.
•
Signal reception is normally better at night than during
the day.
•
Time calibration signal reception takes from two to six
minutes. Take care that you do not perform any button
operations or move the watch during this time.
