will automatically adjust its time
and day settings.

If position information acquisition
fails for some reason, the second
hand will move to “NO” and then
the watch will indicate the current
time and day without adjusting
them.
Note
Reception takes anywhere from
about 30 seconds to about two
minutes.
It can take as long as 13 minutes
when leap second information is
included.
You may experience location
information acquisition
problems when you are in the
vicinity of a time zone
borderline.
The watch’s time and day will
not be indicated correctly if the
Home City (Time Zone) setting
is not right for your location.
Perform position information
acquisition in a representative
city in your time zone or in a
location that is well within the
time zone. Or you can perform a
time information receive
operation to adjust time and day
settings after configuring Home
City (Time Zone) and summer
