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 four
times a day at 2:00 AM, 3:00 AM, 4:00 AM, and 5:00 AM. 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!
• 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.

Hand Setting Mode
This watch is designed to pick up a time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt), and update its time
setting accordingly. The time calibration signal includes
both Standard Time and Daylight Saving Time (summer
time) data.
Current Time Setting
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.
• See "Setting the Digital Time and Date Manually" 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.
1. In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.
2. Use D(+) and B(–) to select the city code you want to
use as your Home City.
• The following are the city codes for major cities in the
Western Europe time zones.
BER and PAR : Berlin, Paris, Milan, Rome,
Amsterdam, Hamburg,
Frankfurt, Vienna
LON : London
3. Press A twice 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 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.

• Signal reception is normally better at night than during the day.
• Time calibration signal reception takes from two to six minutes. Take care that you
do not perform any button operations or move the watch during this time.
• This watch is able to receive the time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt). Signal reception is
possible within the area represented by a circle with a
radius of about 1,000 kilometers.
• At distances further than about 500 kilometers, the
signal may become weak and reception may be
impossible under certain conditions.
• Signal reception may be poor in the shaded area on the
map, even though it is within 1,000 kilometers of the
signal transmitter.

calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 3:00 AM,
4:00 AM, and 5:00 AM each day (calibration times).
Note
• The auto receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
performed if a calibration time is reached while an alarm is sounding, or while you
are making settings (while settings are flashing on the display).
• Auto receipt 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 easily receive the signal.
• When auto receive is turned on, the watch receives the calibration signal for two to
six minutes everyday when the time in the Timekeeping Mode reaches each of the
four calibration times. Do not perform any button operation within six minutes before
or after any of the four calibration times. Doing so can interfere with correct
calibration.
• Remember that reception of the calibration signal depends on the time kept in the
Timekeeping Mode. The receive operation is performed whenever the display shows
one of the four calibration times, regardless of whether or not the Timekeeping Mode
time is actually the correct time.
• When two, three, or four receptions are successful, the watch uses the data of the
last reception for calibration. When only one reception is successful, the watch uses
the data of the successful reception.
About the Receiving Indicator
The receiving indicator shows the strength of the calibration signal being received. For
best reception, be sure to keep the watch in a location where signal strength is
strongest.
