•
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.
•
Even when the watch is within the reception range of the transmitter, signal
reception is impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
•
Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
•
See the information under “Signal Receive Troubleshooting” if you experience
problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch attempts to receive the time
calibration signal automatically up to six times. The start times of the auto receive
operations depend on the current Home City and DST settings.
•
If all of the first three reception operations fail, the watch automatically performs a
fourth receive operation.
•
If any of the remaining receive operations (4, 5, or 6) is successful, any remaining
receive operations are skipped.
•
Auto receive is performed in accordance with the Timekeeping Mode time.

Note
•
Auto receive works only while the watch is in the Timekeeping Mode or World Time
Mode. Auto receive is not performed if an auto receive time is reached while an
alarm is sounding, while a countdown timer operation is in progress, or if a setting
screen (a screen with a flashing setting) is 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 receive the signal easily.
•
When auto receive is turned on, the watch receives the calibration signal for two to
six minutes everyday when the Timekeeping Mode time reaches each of the
calibration times. Do not perform any button operation within six 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 time kept in the
Timekeeping Mode. The receive operation will be performed whenever the display
shows any one of the calibration times, regardless of whether or not the
Timekeeping Mode time is actually the correct time.
•
If more than one auto receive is successful, the watch uses the data from the last
successful receive to adjust settings. When only one reception is successful, the
watch uses the data of the successful reception.
•
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 receive operations.
•
Following reception of the time calibration signal and calibration of the watch’s time
setting, the Level 4 receiving indicator will remain on the display in all modes. The
Level 4 receiving indicator will not be displayed if signal reception was unsuccessful
or after you adjust the current time setting manually.
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.
Receiving indicator
Weak
(Level 1)
Strong
(Level 4)
•
The Level 4 receiving indicator is displayed only when the watch is able to receive
both time and date data successfully. It does not appear when only time data is
received.
•
The Level 4 receiving indicator indicates that at least one of the auto calibration
signal receive operations was successful. Note, however, that the Level 4 receiving
indicator disappears from the display each day when the second auto receive
operation of the day is performed.
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. In the Timekeeping Mode, hold down
D
for about two
seconds until the watch beeps.
•
Release
D
and the message
RC!
appears to indicate
that signal reception has started.
•
Time calibration signal reception normally takes from
two to six 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 while time
calibration signal reception is in progress.

•
After signal reception is complete, the display of the watch changes to the Last
Signal screen.
To configure auto receive settings
1. In the Timekeeping Mode, press
D
to display the last
signal screen.
•
The watch will return automatically to the Timekeeping
Mode if you do not perform any button operation for two
or three minutes after displaying the last signal screen.
2. Hold down
A
until the current auto receive setting
flashes. This is the setting screen.
•
If the auto receive setting does not appear when you
hold down
A
, it means that the city code currently
selected for the Home City is for an area that does not
support calibration signal reception. You cannot turn
auto receive on or off in this case.
3. Use

to cycle through the settings shown below, until the one you want to use is
displayed.

Signal Receive Troubleshooting
Check the following points whenever you experience problems with calibration signal
reception.
Problem
Cannot perform
manual receive.
Auto receive is
turned on, but
the Level 4
receiving
indicator does
not appear on
the display.
Time setting is
incorrect
following signal
reception.
Probable Cause
•
The watch is not in the Timekeeping Mode.
•
Your current Home City is not one of the
following city codes:
BER
,
PAR
, or
LON
.
•
You changed the time setting manually.
•
The watch was not in the Timekeeping
or World Time Mode, or you performed
some button operation during the auto
receive operation.
•
Even if receive is successful, the Level 4
receiving indicator disappears from the
display each day when the second auto
receive operation of the day is
performed.
•
Time data (hour, minutes, seconds) only
was received during the last receive
operation. The Level 4 receiving
indicator appears only when time data
and date data (year, month, day) are
both received.
•
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.
What you should do
•
Enter the Timekeeping Mode
and try again.
•
Select
BER
,
PAR
, or
LON
as
your Home City.
•
Perform manual signal receive
or wait until the next auto
signal receive operation is
performed.
•
Check to make sure the
watch is in a location where it
can receive the signal.
•
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”.
•
This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany.

Note
•
To interrupt a receive operation and return to the Timekeeping Mode, press
D
.
•
If the receive operation is unsuccessful, the message
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
.
Configuring Auto Receive Settings
You can use the procedure in this section to configure the watch to receive the signal
of a specific transmitter, or to receive automatically from the transmitter whose signal
is strongest. You can also turn off auto receive, if you want.
•
Note that you can perform the following procedure only when
LON
,
BER
, or
PAR
is selected as your Home City.
