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.
Applications
The built-in sensors of this watch measure barometric pressure, temperature
and altitude. Measured values are then shown on the display. Such features
make this watch useful when hiking, mountain climbing, or when engaging in
other such outdoor activities.
Keep the watch exposed to bright light

• 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.

Radio-controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting
accordingly.
• This watch is designed to pick up the time calibration signals transmitted in
Germany (Mainflingen), England (Anthorn), the United States (Fort Collins),
China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga).
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" below.
• 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 "Timekeeping" 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.
Operation Guide 3147
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 covered only
partially.

a window
Approximately 50 minutes exposure to indoor fluorescent lighting
• Be sure to read "Power Supply" for important information you need to
