Signal Reception
Precautions
●
When the watch is unable to adjust its time
in accordance with a calibration signal for
some reason, average timekeeping
accuracy is within ±15 seconds per month.
●
Time signal reception is not possible when
any one of the conditions exists.
ー
While battery power is low
ー
While the watch is in the Airplane Mode
or Stopwatch Mode
ー
When power saving is at Level 2 (GPS
signal reception also is not possible at
Level 1.)
ー
While the crown is pulled out
ー
While the temperature of the watch is less
than approximately -10°C (14°F) or
greater than approximately 60°C (140°F)
●
Note that an internal decoding process the
watch
performs after it receives a signal may
cause the time setting to be slightly off (by
less than one second).
●
If the receive operation is successful, the
time and day settings will be adjusted
automatically in accordance with the Home
City (time zone) and summer time settings.
Summer
time will not be applied correctly in
the cases described below.
ー
When the summer time start date and
time, end date and time, or other rules are
changed by authorities
ー
When position information cannot be
acquired correctly
ー
When position information can be
acquired, but it is wrong because the
watch is located near a time zone
boundary, etc.
●
As of July 2015, China does not observe
summer time. If China starts to observe
summer time in the future, the time
displayed
by the watch for China may not be
correct.
Using the Watch on an
Aircraft
Enter the Airplane Mode when in an aircraft or
anywhere else where GPS or time calibration
signal reception is restricted.
Entering the Watch Airplane
Mode
Holding down (C) for about four seconds to
enter the watch’s Airplane Mode. The mode
hand will move to the Airplane mark.
●
Each time (C) is held down for about four
seconds, the watch enters or exits the
Airplane Mode.
