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.
•Be sure to keep all user documentation handy for future reference.
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 even only partially covered.

•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 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.

E-3
•The actual level at which some functions are disabled depends on the watch model.
•Frequent display illumination can run down the battery quickly and require charging.
The following guidelines give an idea of the charging time required to recover from a
single illumination operation.
Approximately 5 minutes exposure to bright sunlight coming in through a window
Approximately 50 minutes exposure to indoor fluorescent lighting
•Be sure to read “Power Supply” (page E-48) for important information you
need to know when exposing the watch to bright light.
If the display of the watch is blank...
If the display of the watch is blank, it means that the Power Saving has turned off the
display to conserve power.
•See “Power Saving” (page E-55) 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
transmitted in Japan (Fukuoka/Saga and Fukushima)
and the United States (Fort Collins, Colorado).
•See the information under “Signal Receive
Troubleshooting”(page E-26) if you experience problems
with time calibration signal reception.

Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration
signal. You also can 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 City (the city where you normally will use the watch). For more
information, see “To specify your Home City”on page E-12.
•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
“To set the
current digital time and date manually”(page E-40) 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.

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 six
times a day. When any auto receive is successful, remaining auto receive
operations are not performed. For more information, see “About Auto Receive”
(page E-20).
•Manual Receive
Manual receive lets you start a time calibration signal reception with the press of a
button. For more information, see “To perform manual receive”on page E-23.

E-16
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 pointing towards a window.
This watch is designed to receive a time calibration signal late at night. Because of
this, you should place the watch near a window as shown in the illustration when you
take it off at night. Make sure there are no metal objects nearby.
