• Signal reception is normally 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.
• When within range of the applicable transmitter, this watch can receive either the
Germany (Mainflingen) or England (Rugby) time calibration signals. See
“Transmitters” for more information.
• Under good reception conditions, signal reception is possible within a radius of
about 1,500 kilometers from a transmitter.

• At distances further than about 500 kilometers from a transmitter, signal reception
may not be possible during certain times of year or times of day. Radio interference
may also cause problems with reception.
• See the information under “Signal Reception Troubleshooting” if you experience
problems with time 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 0:00 a.m., 2:00
a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also
perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto
receive operations are successful.
Note
• Auto receive is turned on whenever LON , PAR , or BER is selected as the Home
City code. For information about turning off auto receive, see “To select the
transmitter mode”.
• Auto receive 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 configuring
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
seven minutes everyday when the time in the Timekeeping Mode reaches each of
the calibration times. Do not perform any button operation within seven minutes
before or after any one of the calibration times. Doing so can interfere with correct
calibration.
• Remember that reception of the calibration signal depends on the current time
shown on the digital display. The receive operation will be performed whenever the
display shows any one of the calibration times, regardless of whether or not the
displayed 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.
• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.
• Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal reception.

To perform manual receive
1. Place the watch on a stable surface so its top (12
o’clock side) is facing towards a window.
2. While any screen other than the last signal screen is on
the display in the Timekeeping Mode, hold down D for
about two seconds until the watch beeps.
3. Release D and the receiving indicator will appear on
the display to indicate that signal reception has started.
• Time calibration signal reception takes from two to seven
minutes, but in some cases it can take up to 14 minutes.
Take care that you do not perform any button operations
or move the watch during this time.
• After signal reception is complete, the watch beeps and the display of the watch
changes to the last signal screen.
Note
• To interrupt a receive operation and return to the Timekeeping Mode, press D.
• If the receive operation is unsuccessful, ERR appears on the display for about one
or two minutes. After that, the watch returns to the Timekeeping Mode.

• You can also change from the last signal or ERR screen to the normal timekeeping
screen by pressing D.
Signal Reception Troubleshooting
Check the following points whenever you experience problems with signal reception.
Problem
Cannot perform
manual receive.
Probable Cause
• The watch is not in the
Timekeeping Mode.
• Your current Home City is not one
of the following city codes: LON ,
PAR , or BER.
• A button operation was performed
or the watch was moved while
signal reception was in progress.
• The transmitter setting is incorrect.
What you should do
• Enter the Timekeeping Mode and
try again.
• Select LON , PAR , or BER as
your Home City.
• Do not perform any button
operations or move the watch while
signal reception is in progress.
• Check to make sure the watch is
in a location where it can receive
the signal.
• Select the transmitter setting
appropriate for your current
location.
The watch does
not perform auto
receive.
The time setting
is incorrect
following signal
reception.
• The watch was not in the
Timekeeping Mode or World Time
Mode when a calibration time
arrived.
• The transmitter setting is incorrect.
• If the time is one hour off, the DST
setting may be incorrect.
• The Home City code setting is not
correct for the area where you are
using the watch.
• Perform manual signal receive or
wait until the next auto signal
receive operation is performed.
• Select the transmitter setting
appropriate for your current
location.
• Change the DST setting to Auto
DST.
• Select the correct Home City code.
• For further information, see “Important!” under “Time Calibration Signal Reception”
and “Radio-controlled Timekeeping Precautions”.
World Time
World Time digitally displays the current time in 30 cities
(29 time zones) around the world.
• The watch will perform a signal reception even if it is in
the World Time Mode when a calibration time is
reached. If this happens, the World Time Mode time
settings will be adjusted in accordance with the
Timekeeping Mode’s Home City time.
• For full information on city codes, see the “City Code
Table”.
• All of the operations in this section are performed in the
World Time Mode, which you enter by pressing C.
GMT
City code
Current time in the
zone of the
selected city code
To view the time in another city
In the World Time Mode, press D to scroll eastwardly through city codes (time
zones).
• The city code is displayed for about two seconds, and then it is replaced with the
current time for that city code. Pressing A while the time is displayed in the World
Time Mode causes the city code of the currently selected zone to appear.
• When the currently selected time zone is one that includes mostly ocean, a value
indicating the zone's Greenwich Mean Time differential appears in place of a city
code.
• If the current time shown for a city is wrong, check your Home City time settings and
make the necessary changes.
To toggle a city code time between Standard Time and Daylight Saving Time
1. In the World Time Mode, use D to display the city
code (time zone) whose Standard Time/Daylight Saving
Time setting you want to change.
2. Hold down A to toggle between Daylight Saving Time
(DST indicator displayed) and Standard Time (DST
indicator not displayed).
• The DST indicator appears on the display whenever you
display a city code for which Daylight Saving Time is
turned on.
• You cannot toggle between Daylight Saving Time and Standard Time if the displayed
city code is GMT or the city code that is currently selected as the Home City in the
Timekeeping Mode. To change the DST setting of your Home City, use the
procedure under “To change the Daylight Saving Time (summer time) setting”.
• Note that the DST/Standard Time setting affects only the currently displayed city
code. Other city codes are not affected.
DST indicator
Alarm
When the alarm is turned on, the alarm sounds when the
alarm time is reached. You can also turn on an Hourly
Time Signal, which will cause the watch to beep twice
every hour on the hour.
• When the alarm is turned on, the alarm screen
alternates between qmOo (alarm on) and the current
alarm time (hour and minutes). When the alarm is off,
qmOw (alarm off) remains on the alarm screen.
• All of the operations in this section are performed in the
Alarm Mode, which you enter by pressing C.
• Pressing D in the Alarm Mode toggles between the
alarm screen and Hourly Time Signal screen.
