Important!
•
When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’ clock side facing towards a window.
This watch is designed to receive a time calibration signal late at night. Because of
this, you should place the watch near a window as shown in the illustration when
you take it off at night. Make sure there are no metal objects nearby.

Proper signal reception can be diffi cult or even impossible under the conditions listed
below.

•
Signal reception normally is 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.
•
The time calibration signal the watch will attempt to pick up depends on its current
Home City code setting as shown below. If you use the watch in Japan or Europe (each
of which has two different transmitter locations), it will try to receive the time calibration
signal from one of the transmitters in your current location. If it cannot receive the
signal, it will then try to receive the time calibration signal from the other transmitter
.

far from the time calibration signal transmitters, and so certain conditions may
cause problems with signal reception.

U.K. and German Signals
•
Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference may also cause problems with reception.
Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
•
In April 2007, the U.K. signal transmitter was moved from Rugby to Anthorn, which
resulted in a slight shift in the approximate reception range of the signal. The shift is so
slight that there is virtually no change in the ability to receive the signal.
•
Even when the watch is within the reception range of a transmitter, signal reception may
be impossible at times due to the effects of geographic contours, structures, weather,
the season of the year, the time of day, radio interference, etc. Note that the signal
becomes weaker at distances of approximately 500 kilometers from the transmitter,
which means that the infl uence of the conditions listed above becomes even greater.
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.

Note
•
When a calibration time is reached
,
the watch will receive the calibration signal
only if it is in either the Timekeeping Mode or World Time Mode
.
Reception is not
performed if a calibration time is reached while you are confi guring settings
.
•
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.
•
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. Avoid
performing 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 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 displayed
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.
Receivin
indicator
Weak
(Level 0)
Strong
(Level 3)
•
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 fi nding 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
.
•
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 fi rst auto receive operation of the day
is performed.
To perform manual receive
Receivin
indicator
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
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.
•
After signal reception is complete, 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, 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.
