• Signal reception is normally better at night than during the day.

• Time calibration signal reception takes from two to six minutes, but 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.

• 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.

• This watch is designed to receive the time calibration signal transmitted from

Mainflingen, Germany and the signal from Rugby, England.  Signal reception is
possible within the area represented by a circle with a radius of about 1,500
kilometers.

500 kilometers

• 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 will be 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 Reception Troubleshooting” if you experience

problems with time calibration signal reception.

About Auto Receive
The watch receives the time calibration signal automatically up to six times a day.
When any auto receive is successful, the remaining auto receive operations are not
performed.  The reception schedule (calibration times) depends on your currently
selected Home City, and whether standard time or Daylight Saving Time is selected
for your Home City.

• Auto receive is turned on whenever LIS, LON, BCN, MAD, PAR, MIL, ROM, BER,

STO, or ATH is selected as the Home City code.

• 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 while a
setting screen (a screen with a flashing setting) is on the display.

• Auto receive 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

five minutes everyday when the Timekeeping Mode time reaches each of the
calibration times. Do not perform any button operation within five 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 actually is the correct time.

• Calibration signal reception is disabled while a countdown timer operation is in

progress.

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 receive operations.

• Following reception of the time calibration signal and calibration of the watch’s time

setting, the Level 3 receiving indicator will remain on the display in all modes. The
Level 3 receiving indicator will not be displayed if signal reception was unsuccessful
or after you adjust the current time setting manually.

Receiving indicator

• The Level 3 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 3 receiving indicator indicates that at least one of the auto calibration

signal receive operations was successful. Note, however, that the Level 3 receiving
indicator is cleared from the display when the first auto receive operation of the day
is performed.

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 

RC! appears on the display.

• Time calibration signal reception takes from two to six

minutes, but 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.

• After signal reception is complete, the display of the

watch changes to the Last Signal screen.

Receiving indicator

• 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.

• Calibration signal reception is disabled while a countdown timer operation is in

progress.

1. In the Timekeeping Mode, press D to display the Last

Signal screen.

2. Hold down A until the receiving indicator and current

auto receive setting (

 or 

) start to flash. This is

the setting screen.

• Note that the setting screen will not appear if the

currently selected Home City is one that does not
support time calibration reception.

3. Press D to toggle auto receive on (

) and off (

).

Signal Receive Troubleshooting
Check the following points whenever you experience problems with calibration signal
reception.

• For further information, see “Important!” under “Time Calibration Signal Reception”

and “Radio-controlled Timekeeping Precautions”.

The World Time Mode shows you the current time in 48
cities (29 time zones) around the world.

• If the current time shown for a city is wrong, check your

Home City time settings and make the necessary
changes.

• All of the operations in this section are performed in the
