Important!
•
Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You can also perform manual receive or you
can set the time manually.
•
The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between city codes and transmitters, see “Home
City Codes and Transmitters”.
•
Under factory default settings, auto receive is turned off for all of the following city
codes:
MOW
(Moscow),
HKG
(Hong Kong),
BJS
(Beijing),
HNL
(Honolulu), and
ANC
(Anchorage). For details about turning on auto receive for these city codes, see
“To turn auto receive on and off”.
•
You can disable time signal reception, if you want. See “To turn auto receive on and
off” for more information.
•
See the maps under “Reception Ranges” for information about the reception ranges
of the watch.
•
If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
•
Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to
six times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. For more information, see “About Auto Receive”.
•
Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive”.
Important!
•
When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side facing towards a window.
Make sure there are no metal objects nearby.
12 o’clock
or
•
Make sure the watch is facing the right way.
•
Proper signal reception can be difficult or even impossible under the conditions listed
below.
•
Signal reception normally is better at night than during the day.
•
Time calibration signal reception takes from two to seven minutes, but in some
cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.

•
The time calibration signal the watch will attempt to pick up depends on its current
Home City code setting as shown below. If you use the watch in Japan or Europe
(each of which has two different transmitter locations), it will try to receive the time
calibration signal from one of the transmitters in your current location. If it cannot
receive the signal, it will then try to receive the time calibration signal from the other
transmitter.

Home City Codes and Transmitters
* The areas covered by the
MOW
,
HKG
,
BJS
,
HNL
, and
ANC
city codes are quite
far from the time calibration signal transmitters, and so certain conditions may
cause problems with signal reception.
