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 signal transmitted in
Germany (Mainflingen), England (Rugby), and the United States (Fort
Collins) and the time calibration signals transmitted in Japan.
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.
To specify your Home City
1. In the Timekeeping Mode, hold down E until
the city code starts to flash, which indicates
the setting screen.
2. Press C (east) and D (west) to select the

3. Press E to exit the setting screen.
• Normally, your watch should show the correct time as soon as you select
your Home City code. If it does not, it should adjust automatically after the
next auto receive operation (in the middle of the night). You also can
perform manual receive or you can set the time manually.
• The watch will receive the time calibration signal automatically from the
applicable transmitter (in the middle of the night) and update its settings
accordingly. For information about the relationship between city codes and
transmitters, see “Transmitters”.
• See the maps under “Reception Ranges” for information about the
reception ranges of the watch.
• You can disable time signal reception, if you want. See “To turn auto receive
on and off” for more information.
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
up to six times a day. When any auto receive is successful, the remaining
auto receive operations are not performed. For more information, see “About
Auto Receive”.
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press
of a button. For more information, see “To perform manual receive”.
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 facing towards a
window. Make sure there are no metal objects nearby.
12 o’clock

• The watch should not be facing the wrong way.
• Proper signal reception can be difficult or even impossible under the
conditions listed below.

• Signal reception normally is better at night than during the day.
• Time calibration signal reception takes from two to seven minutes, but in
some cases it can take as long as 14 minutes. Take care that you do not
perform any button operations or move the watch during this time.

• Signal reception may not be possible at the distances noted below during
certain times of the year or day. Radio interference may also cause
problems with reception.

• Even when the watch is within the reception range of the transmitter, signal
reception will be impossible if the signal is blocked by mountains or other
geological formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and
seasonal changes.
• See the information under “Signal Reception Troubleshooting” if you
experience problems with time calibration signal reception.
About Auto Receive
The watch receives the time calibration signal automatically up to six times a
day. When any auto receive is successful, the remaining auto receive
operations are not performed. The reception schedule (calibration times)
depends on your currently selected Home City, and whether standard time or
Daylight Saving Time is selected for your Home City.

Note
• When a calibration time is reached, the watch will receive the calibration
signal only if it is in either the Timekeeping Mode or World Time Mode.
Reception is not performed if a calibration time is reached while you are
configuring settings.
• Auto receive of the calibration signal is designed to be performed early in
the morning, while you sleep (provided that the Timekeeping Mode time is
set correctly). Before going to bed for the night, remove the watch from your
wrist, and put it in a location where it can receive the signal easily.
