Time Adjustment Using a
Time Signal
Overview
The watch’s time and day settings can be
configured in accordance with a received time
calibration signal.
Important!
●
In order to make it possible for the
current time setting to be adjusted
correctly based on time calibration
signal reception, you need to specify
the time zone where you are using the
watch.
●
If the watch was unable to connect with
a phone even once for time adjustment
during the previous day while
connection with a phone is being used,
it will automatically try to receive a time
calibration signal.
●
When you are on an aircraft or in any
other location where radio signals may
cause problems, enable the watch’s
Airplane Mode to disable connection
with your phone.
l
Using the Watch in a Medical
Facility or Aircraft
Note
●
Areas where time calibration signal
reception is supported are limited.
When the watch is in an area where
time calibration signal reception is not
possible, connect with a phone to
adjust time and day settings.
