GPS signal reception Q & A
GPS signal reception
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.

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. 29.
