About Auto Receive
The watch receives the time calibration signal automatically up to six times a day (fi ve 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.

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.
−
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: 1,500 kilometers (910 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.
As of September 2009, China does not use Daylight Saving Time (DST). If China does go to the
Daylight Saving Time system in the future, some functions of this watch may no longer operate
correctly.

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.
5:00 am
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.

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 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.
