Operation Guide 5173
Press 3. A twice to exit the setting mode.
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 also can 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 Code” and “Transmitters”.
See the maps under “Approximate Reception Ranges” for information about the •
reception ranges of the watch.
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 (five times for the China signal). When any auto receive is successful,
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 pointing 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.
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.

The areas covered by the * HNL, ANC, and MOW city codes are quite far from the
time calibration signal transmitters, and so certain conditions may cause problems
with signal reception.
Calibration signal reception is disabled while a countdown timer operation is in •
progress.

Signal reception may not be possible at the distances that are further than those •
noted below during certain times of the year or day. Radio interference also may
cause problems with reception.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles) −

Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles) −
Shangqiu (China) transmitter: 1500 kilometers (910 miles) −
Even when the watch is within the reception range of the transmitter, signal •
reception will be impossible if the signal is blocked by mountains or other
geological formations between the watch and signal source.
Signal reception is affected by weather, atmospheric conditions, and seasonal •
changes.
As of July 2010, China does not use Daylight Saving Time (DST). If China does go •
to the Daylight Saving Time system in the future, some functions of this watch may
no longer operate correctly.
About Auto Receive
The watch receives the time calibration signal automatically up to six times a day
(five times for the China signal). When any auto receive is successful, 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.

Note
When a calibration time is reached, the watch will receive the calibration signal •
only if it is in either the Timekeeping Mode or World Time Mode. Reception is not
performed if a calibration time is reached while you are configuring settings.
Auto receive of the calibration signal is designed to be performed early in the •
morning, while you sleep (provided that the Timekeeping Mode time is set
correctly). Before going to bed for the night, remove the watch from your wrist, and
put it in a location where it can receive the signal easily.
The watch receives the calibration signal for two to 14 minutes everyday when •
the time in the Timekeeping Mode reaches a calibration time. Do not perform any
button operation within 14 minutes before or after the calibration times. Doing so
can interfere with correct calibration.
Remember that reception of the calibration signal depends on the current time in •
your Home City, as kept in the Timekeeping Mode.
To perform manual receive
Place the watch on a stable surface so its 12 o’clock 1.
side is facing towards a window.
In the Timekeeping Mode, hold down 2. A for about two
seconds until the watch beeps.
The digital display will go blank, and the left dial hand 3.
will move to R (READY). This indicates that the watch is
getting ready for time calibration signal reception.
See the information under “Signal Reception •
Troubleshooting” if you experience problems.
The left dial hand will move to • W (WORK) and stay
there while actual reception is in progress.
If signal reception is unstable during reception, the •
left dial hand may move between W (WORK) and R
(READY).
The hour and minute hands continue to keep time •
normally.
