• 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.

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.
• When using the watch outside the ranges of the U.S. and Japanese time signal
transmitters, you have to adjust the current time setting manually as required. See
"Timekeeping" for more information about manual time setting.

the analog time setting is automatically adjusted whenever you change the digital
setting. See "Analog Timekeeping" for more information.

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.

Hand Setting Mode
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
signal transmitted in the United States (Fort Collins,
Colorado) and the time calibration signals transmitted in
Japan.
• 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.
1. In the Timekeeping Mode, hold down A until the
transmitter indicator (
) starts to flash, which
US
indicates the setting screen.
• The second hand will move at high speed to the 12
o'clock position, where it will stop.
2. Press C once so the city code is flashing on the display.
3. Use D (east) and B (west) to scroll through the city
codes until the one you want to use as your Home City
is displayed.
• 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" for important information you need to know
when exposing the watch to bright light.

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.

If the Power Saving indicator (
) is flashing on the display,
PS
it means that the display is blank because the watch's
Power Saving function has turned it off to conserve power.
Power Saving automatically turns off the display and
enters a sleep state whenever your watch is left for a
certain period in an area 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 will recover from the sleep state if you move it
to a well-lit area or if you press any button.
• See "Power Saving Function" for more information.
• The operational procedures for Modules 3311 and 5052
are identical. All of the illustrations in this manual show
Module 3311.
• 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
