• 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.

• 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.

Receiving indicator

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.

• 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.

Cannot perform
manual receive.

• 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.

• 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 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.

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.

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

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.
