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.

hours. Because of this, the radio-controlled atomic timekeeping function will not
display the correct time for Newfoundland, Canada.
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 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.

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".
• 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.
• As of March 2010, China does not use Daylight Saving Time (DST). If China does go
to the Daylight Saving Time system in the future, some functions of this watch may
no longer operate correctly.
• Using this watch in a country covered by a time calibration that is different from the
countries it supports may result in incorrect time indication due to local application of
summer time, etc.
Operation Guide 5135
The electricity generated by the solar cell of the watch is
stored by a rechargeable 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.
