•
Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference also may 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)
Shangqiu (China) transmitter: 500 kilometers (310 miles)
•
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” (page E-28) if you
experience problems with time calibration signal reception.

About Auto Receive
The watch receives the time calibration signal automatically up to 6 times a day (5
times a day for the Chinese calibration signal). 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 a calibration time. Do not perform any
button operation within seven minutes before or after 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.
E-24
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. The receiving indicator is displayed while an auto or manual receive
operation is in progress.
Receiving indicator
Weak
Strong
•
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.
•
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.
E-25
To perform manual receive
1. In the Timekeeping Mode, hold down
D
for about two
seconds.
•
Time calibration signal reception takes from two to
seven minutes. Take care that you do not perform
any button operations or move the watch during this
time.
•
The watch will beep when receive is successful.
After the time setting is corrected, it will appear on
the display.
•
If receive fails for some reason,
ERR
will appear on
the display and the time setting will not be changed.
2. To return to the Timekeeping Mode, press
D
or do not
perform any operation for one or two minutes.
Note
•
To interrupt a receive operation and return to normal
timekeeping, press any button.

•
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.
•
Change the DST setting to Auto
DST (page E-47).
•
Select the correct Home City code
(page E-12).

World Time
The World Time Mode digitally displays the current time in
48 cities (31 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 (page E-43).
•
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.
•
All of the operations in this section are performed in the
World Time Mode, which you enter by pressing
C
(page E-8).
