Note
●
Even if you are within the normal
reception range of a time calibration
signal, reception may be made
impossible by the following factors:
geographic contours, weather, the
season, the time of day, wireless
noise.
Auto Time Calibration Signal
Receive
An automatic time calibration signal receive
operation is performed and the time and day
settings are adjusted between midnight and
5:00 a.m. Once a signal receive operation is
successful, no more auto receive operations
are performed that day.
Getting Ready
Enter the Calendar Mode.
l
Navigating Between Modes

Place the watch near a window or some other
location appropriate for signal reception.
●
The second hand points to [RC] while the
receive operation in progress.
●
When the receive operation is successful,
the time and day settings will be adjusted
automatically.
Note
●
Reception takes anywhere from about
two minutes to about 10 minutes. It can
take as long as 20 minutes.
●
If the watch connects with a phone and
adjusts its time setting, the watch will
not perform auto receive of a time
calibration signal for the rest of that day
or the next day.
Manual Time Signal Receive
1.
Place the watch near a window or some
other location appropriate for time signal
reception.
2.

Navigating Between Modes
3.
Hold down (B) for at least 0.5 seconds until
the second hand points to [RC].
This indicates that the receive operation

Note
●
The receive operation takes anywhere
from about two minutes to about 10
minutes. It can take as long as 20
minutes.
●
Time calibration signal reception is
better at night than during the day.
●
A time calibration signal operation
cannot be received while the watch is
paired with a phone.
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.
●
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).
●
Time calibration signal reception is not
possible under the conditions described
below.
ー
While battery power is low
ー
While the watch is in the Stopwatch Mode,
Timer Mode, or Alarm Mode
ー
At Power Saving Level 2
ー
While the crown is pulled out
ー
While a timer countdown operation is in
progress
ー
While the Home City setting is a time zone
where time signal reception is not
possible
ー
While the watch is outside the time signal
reception range
●
When the receive operation is successful,
the time and/or day settings will be adjusted
automatically. Summer time will not be
applied correctly in the case described
below.
ー
When the summer time start date and
time, end date and time, or other rules are
changed by authorities
●
If your watch is connected with a phone,
settings must be configured so G-SHOCK
Connected can acquire location
information. Even if you are in an area that
is within the reception range of a time signal,
reception will not be performed if settings
are configured in a way that makes signal
reception impossible.
●
As of July 2018, 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.
