General Guide

• Press C to change from mode to mode.
• In any mode (except when a setting screen is on the display), press L to
illuminate the display.
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 3150
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 only partially
covered.
