* The areas covered by the HNL, ANC, and MOW city codes are quite far from the
time calibration signal transmitters, and so certain conditions may cause problems
with signal reception.
• Calibration signal reception is disabled while a countdown timer operation is in
progress.

• Signal reception may not be possible at the distances that are further than those
noted below during certain times of the year or day. Radio interference also may
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.

About Auto Receive
The watch receives the time calibration signal automatically up to six times a day (five
times for the China signal). When any auto receive is successful, 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 configuring 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 14 minutes everyday when the
time in the Timekeeping Mode reaches a calibration time. Do not perform any button
operation within 14 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
your Home City, as kept in the Timekeeping Mode.
To perform manual receive
1.Place the watch on a stable surface so its 12 o’clock
side is facing towards a window.
2.In the Timekeeping Mode, hold down A for about two
seconds until the watch beeps.
3.The digital display will go blank, and the left dial hand
will move to R (READY). This indicates that the watch is
getting ready for time calibration signal reception.
• See the information under “Signal Reception
Troubleshooting” if you experience problems.
• The left dial hand will move to W (WORK) and stay there
while actual reception is in progress.
• If signal reception is unstable during reception, the left
dial hand may move between W (WORK) and
R (READY).
• The hour and minute hands continue to keep time
normally.

R (READY)W (WORK)
• 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 a signal receive operation is successful, GET
appears on the upper display and the lower display
shows the time and date of the successful operation.
The watch will adjust its time setting in accordance to
with the information provided by the signal.
• The watch will return to the Timekeeping Mode if you
press A or if you do not perform any operation for
about one or two minutes.
• ERR will appear on the upper display if the receive
operation is not successful. The watch will not adjust its
time setting in this case. Press A to return to the
Timekeeping Mode.

Note
• To interrupt a receive operation and return to the Timekeeping Mode, press any
button.
To check the latest signal reception results
In the Timekeeping Mode, press A to view the last successful receive time and date.
Press A again to return to the previous screen.
