Calibration Signal Reception
Precautions
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.
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.

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.
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).
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
