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.

Proper signal reception can be difficult or even impossible under the conditions listed below. •

or a mobile

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.
Home City Code Transmitter Frequency
LON, PAR, BER, ATH, LIS, MAD,
ROM, STO, MOW*
Anthorn (England) 60.0 kHz
Mainflingen (Germany) 77.5 kHz
HKG, BJS Shangqiu City (China) 68.5 kHz
TPE, SEL, TYO
Fukushima (Japan) 40.0 kHz
Fukuoka/Saga (Japan) 60.0 kHz
HNL*, ANC*, LAX, DEN, CHI, NYC,
YVR, YEA, MEX, MIA, YTO, YHZ, YYT
Fort Collins, Colorado (the United States) 60.0 kHz
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 September 2009, 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 side is facing towards 1.
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 will move to 3.
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. •
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.
When a signal receive operation is successful, • GET appears on the upper
display and the lower display shows the time and date of the successful
operation. The watch will adjust its time setting in accordance with the
information provided by the signal.
The watch will return to the Timekeeping Mode if you press • A or if you do
not perform any operation for about one or two minutes.
• ERR will appear on the upper display if the receive operation is not
successful. The watch will not adjust its time setting in this case. Press A
to return to the Timekeeping Mode.
Note
• To interrupt a receive operation and return to the Timekeeping Mode, press
any button.
To check the latest signal reception results
In the Timekeeping Mode, press A to view the last successful receive time and date.
