Adjusting Time
Settings Manually
You can use the procedure below to adjust the
watch’s time and day settings when GPS and
time calibration signal reception is not
possible for some reason.
Selecting a Time Zone
Use the procedure in this section to select a
city (time zone) to use as your Home City. If
you are in an area that observes summer time,
you can also enable or disable summer time.
Note
●
The initial factory default summer
time setting for all cities (time zones)
is “AT (AUTO)”. With this setting, the
watch automatically switches
between summer time and standard
time as required. The “AT (AUTO)”
setting lets you use the watch
without worrying about changing the
summer time setting.
●
When performing a manual
operation to select a time zone for
which there is no city name
displayed, use “STD” or “DST” for
the summer time setting.
●
In the cases described below,
receiving GPS position information
will automatically cause “AT
(AUTO)” to be selected for the
summer time setting.
ー
When the time zone of the current
receive operation is different from
the watch’s time zone setting prior
to the receive operation.
ー
When the time zone is
unchanged, but the acquired
position information is for a
geographic area with different
summer time rules (start date, end
date)
