For full information on city codes, see the “City Code Table”.
•
Note that this watch does not have a city code that corresponds to
Newfoundland.
3. Press

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 “Time Calibration Signal Reception” and “Transmitters”.
•
See the maps under “Approximate Reception Ranges” for information about
the reception ranges of the watch.
•
Under factory default settings, auto receive is turned off for all of the
following city codes:
HKG
(Hong Kong),
HNL
(Honolulu),and
ANC
(Anchorage). For details about turning on auto receive for these city codes,
see “To turn auto receive on and off”.
•
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. This watch is designed to receive a time calibration signal late at
night. Because of this, you should place the watch near a window as shown
in the illustration when you take it off at night. Make sure there are no metal
objects nearby.
12 o’clock
or
•
Make sure the watch is facing the right 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.

Japan Signal
•
In April 2007, the U.K. signal transmitter was moved from Rugby to
Anthorn, which resulted in a slight shift in the approximate reception range
of the signal. The shift is so slight that there is virtually no change in the
ability to receive the signal.
•
Even when the watch is within the reception range of a transmitter, signal
reception may be impossible at times due to the effects of geographic
contours, structures, weather, the season of the year, the time of day, radio
interference, etc. Note that the signal becomes weaker at distances of
approximately 500 kilometers from the transmitter, which means that the
influence of the conditions listed above becomes even greater.
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.
