GPS signal reception Q & A
Q: When the watch is moved to a different time zone, does the
watch automatically display the local time?
A: The watch does not automatically display the local time just by
being moved. If you are in a place where GPS signals can be
easily received, adjust the time zone. The watch automatically
displays the local time.
When you are in a place where GPS signals cannot be received,
manually set the time zone.
 Manual time zone setting P . 21
The watch can be set to all time zones around the world.
Q: Is DST (Daylight Saving Time) automatically changed by
receiving GPS signals?
A: Manually set DST (Daylight Saving Time).
 Set DST (Daylight Saving Time)
(GPS signals from GPS satellites do not include information
about DST (Daylight Saving Time).)
Even in the same time zone, some countries and regions do not
adopt DST (Daylight Saving Time).
 DST (Daylight Saving Time) P . 11
Q: Is it necessary to carry out special operation for years in which a
leap second is added?
A: No special operation is necessary.
Since the watch receives leap second data at the same time of
receiving GPS signals on or after June 1st and December 1st,
a leap second is automatically added by periodically receiving
GPS signals. For details, refer to "Leap second (automatic leap
second reception function)  P . 26.
