Time Adjustment Using a
Time Signal
Overview
The watch’s time and day settings can be
adjusted in accordance with a received time
signal.
Important!
●
If you are in a location where a time
signal can be received and you want
to receive the signal, select a city in
your time zone that supports time
signal reception as your Home City.
The watch will not indicate the
correct time if the Home City setting
is wrong.
●
The watch will normally not perform
auto signal receive while it is paired
with a phone. However, auto receive
will be performed if there is no
connection between the watch and
phone for more than one day.
Note
●
Areas where time signal reception is
supported are limited. When the
watch in an area where time signal
reception is not possible, connect
with a phone to adjust time and day
settings.
