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
In any mode besides the Timekeeping
Mode
ー
When the watch is at Level 2 power
saving
ー
While a compass reading, barometric
pressure measurement, temperature
measurement, or altitude measurement
operation is in progress
ー
While the barometric pressure change
indication is enabled
ー
While a timer countdown operation is in
progress
ー
While the Home City area setting is one
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
●
As of January 2021, 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.
