Calibration Signal Reception
Precautions
• Auto receive can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• Signal reception is not possible when any one of the following
conditions exists.
• Battery at Level 3 to Level 5
• Recover mode (See “Recover Mode”.)
• Receipt of a calibration signal causes the digital time to be
adjusted first, followed by adjustment of the analog time. In order
to ensure proper correction of the analog time, be sure to match
the analog time with the digital time before performing a receive
operation.
• Pressing any button while auto receive is in progress will
terminate it.
• 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.
• Receive is cancelled if an alarm operation starts while it is being
performed.
When the Home City is HKG, TYO, or SEL
ON
Auto receive and auto transmitter selection are turned on. The
watch selects either the Otakadoya Mountain signal (40 kHz)
or the Hagane Mountain signal (60 kHz) automatically,
whichever is strongest.
• The transmitter from which a signal last was received
successfully will be given priority for the next auto receive
operation.

Selecting this setting turns off auto receive and auto
transmitter selection.
