Radio-controlled Timekeeping

This watch receives a time calibration signal and update
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 from Rugby, England and the signal
from Mainflingen, Germany.
Current Time Setting
This watch automatically adjusts its digital 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.

Hour hand
When using the watch that is outside of the range of the transmitters in Rugby and
Mainflingen, you need to manually adjust the time as required. See Timekeeping
for information about manual settings.
The analog time of this watch is synchronized with the digital time. Because of this,
the analog time setting is automatically adjusted whenever you change the digital
setting. See Analog Timekeeping for more information.
To set your Home City
1. In the Timekeeping Mode, hold down A until the
transmitter indicator (
A/T, MSF, or
DCF) starts to
flash, which indicates the setting screen.
If the displayed transmitter indicator shows something
other than
A/T, use D to display A/T before
advancing to the next step.
2. Press C to display the city code setting screen.
3. Use D (east) and B (west) to select the city code you
want to use as your Home City.
City code
The following are the city codes for major cities in the Western Europe time
LON: London
PAR and BER: Paris, Berlin, Milan, Rome, Amsterdam, Hamburg, Frankfurt,
Vienna, Barcelona, Madrid
4. Press A twice to exit the setting screen.
The first press of A displays the 12/24-hour setting screen. Pressing A again exits
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 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.
See Transmitters for details about the transmitter indicator.
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 automatically picks up the time calibration signal five
times a day at 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. 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.

Proper signal reception can be difficult or even impossible under the conditions listed

Time calibration signal reception takes from two to five minutes, but in some cases it
can take as long as 12 minutes. Take care that you do not perform any button
operations or move the watch during this time.
