Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference may also cause problems with
reception.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
Even when the watch is within the reception range of a transmitter, signal reception
may be impossible at times due to the effects of geographic contours, structures,
weather, the season of the year, the time of day, radio interference, etc. Note that
the signal becomes weaker at distances of approximately 500 kilometers from the
transmitter, which means that the influence of the conditions listed above becomes
even greater.
About 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. The reception schedule (calibration times) depends on your currently
selected Home City, and whether standard time or Daylight Saving Time is selected
for your Home City.

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.

The areas covered by the

city codes are quite
far from the time calibration signal transmitters, and so certain conditions may
cause problems with signal reception.

Proper signal reception can be difficult or even impossible under the conditions
listed below.
Inside or
among
buildings
Inside a
vehicle
Near
household
appliances,
office

or a mobile
phone
Near a

site, airport,
or other

Among
or behind

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.
E-14
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.
This watch is designed to receive a time calibration signal late at night. Because of
this, you should place the watch near a window as shown in the illustration when
you take it off at night. Make sure there are no metal objects nearby.
12 o’clock
or
Make sure the watch is facing the right way.
E-13
If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting (page E-45).
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”
(page E-18).
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” (page E-24).
E-12
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
(page E-24) or you can set the time manually (page E-40).
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” (page E-16).
Under factory default settings, auto receive is turned off for all of the following city
codes:
HNL
(Honolulu),
ANC
(Anchorage),
MOW
(Moscow),
HKG
(Hong Kong), and
BJS
(Beijing). For details about turning on auto receive for these city codes, see “To
turn auto receive on and off” on page E-25.
You can disable time signal reception, if you want. See “To turn auto receive on
and off” on page E-25 for more information.
See the maps under “Approximate Reception Ranges” (page E-17) for information
about the reception ranges of the watch.
