Acquiring GPS Position
Information Manually
You can use a button operation to
acquire GPS position information and
adjust your Home City (time zone), time,
and day settings in accordance with your
current location.
Note
GPS signal reception requires
●
large amounts of power.
Perform it only when necessary.
Getting ready
The receive operation is performed only
while the watch is in the Timekeeping
Mode (normal timekeeping).
Normally the mode hand points to the
●
current day of the week.
Navigating Between Modes
l
1. Move to a location appropriate for
signal reception and orient the watch
so its display is pointed straight up at
the sky.
2. Hold down (B) for at least three
seconds. Release the button as soon
as the second hand points to "T+P".
The second hand will move in the
●
following sequence: "YES" or
"NO" n "T (TIME)" n "T+P".
This indicates that position
●
information acquisition has
started. The mode hand will rotate
a number of times while
information acquisition is in
progress.

If position information acquisition
●
is successful, the second hand will
move to "YES" and then the watch
will automatically adjust its time
and day settings. The watch will
also display the acquired Home
City (time zone) and the
approximate latitude of your
current position.

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.
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
time settings manually.
