Calibration Signal Reception
Precautions
•
Auto Receive is not performed while the watch is in the Stopwatch
Mode.
•
Pressing any button while auto receive is in progress will cause the
watch to exit the receive operation.
•
Make sure you are within the range of a calibration signal
transmitter before performing the receive operation. Remember
that geographic contours, nearby buildings, the season, or the time
of day can make reception impossible even when you are within
range of the transmitter.
•
Proper reception may be impossible if there is something blocking
the signal. If reception is unsuccessful, try again.
•
This watch is designed to adjust its current time setting in
accordance with the calibration signal transmitted in Japan and
the United States only. Note that you will need to make your own
adjustments when using this watch outside of Japan or the United
States, or in any area that is outside the range of one of the
receivable time calibration signal transmitters.
•
When the watch is unable to adjust its time using the calibration
signal for some reason, timekeeping accuracy is within ±20
seconds per month.
•
Strong electrostatic charge can cause timekeeping error.
•
The watch’s calendar shows dates up to the year 2099. Attempting
a receive operation after that causes an error.
Troubleshooting
2. Time calibration signal reception is successful, but the
hourly time signal and current time are slightly off.
•
After the watch receives the time calibration signal, it performs an
internal decoding process before updating its time setting. Because
of this, the time setting may be off slightly (within one second).
3. Time calibration signal reception is successful, but the
current time setting is wrong.
•
Is your Home City setting correct? See “To confi gure Home City
settings” for more information.
•
If you cannot receive the calibration signal or if the time setting is
incorrect after signal reception, check the setup of the watch.
•
The following are the watch’s factory default settings, which are
confi gured automatically whenever you have the battery of the
watch replaced.

Location
Reception is diffi cult and may even be impossible in the locations
described below. Avoid such locations when performing signal
reception.
•
You should think of your watch as operating like a radio or TV when
it is receiving the calibration signal.
Among or near buildings Near high-voltage lines
Inside an automobile, train,
plane, or other vehicle
Next to a household appliance
or offi ce equipment (TV,
speaker, fax, computer, cell
phone, etc.)
At a construction site, airport,
or other location where there
is radio interference
Near mountains
If you are experiencing problems with reception, move away
from the types of locations described above to a location with
better reception, and try again.
Stopwatch
The stopwatch measures elapsed time in units of 1 second up to
59 minutes, 59 seconds (60 minutes). When the maximum limit is
reached, the elapsed time returns to zero automatically and timing
continues from there.
•
To enter the Stopwatch Mode, press the
C
button while in the
Timekeeping Mode.

Press the
B
button to return to the Timekeeping Mode.
•
Note that leaving the stopwatch running will run down the
battery.
1. The watch cannot receive the time calibration signal.
•
Is there something in the immediate area that may be interfering
with reception?
Even if you are within the reception range of a transmitter,
electrical noise or objects between you and the transmitter can
interfere with reception. Avoid such areas during signal reception.
See “Location” for more information.
•
Are you within the reception range of a transmitter?
See “Reception Ranges” for information about areas where the
watch can receive the signal.
•
Do you have the correct Home City code selected?
For details about setting the correct Home City, see “To confi gure
Home City settings”.
•
Is the signal being transmitted?
Transmission of time calibration signals may be interrupted
occasionally due to maintenance, lightning, etc.
