To check the result of the last signal
receive operation
In the Timekeeping Mode, press the
BB
BB
B button. This enters
the Receive Result Mode.
• If the watch was able to perform a successful signal receive
operation since midnight, the second hand will move to GET. If
the watch has been unable to receive any signal successfully, the
second hand will move to NG.
• To return to the Timekeeping Mode, press the B button three
times.
• The watch will also return to the Timekeeping Mode if you do not
perform any operation for about two or three minutes.
GET
NG
The current receive result is cleared each day at midnight.
This means GET indicates successful signal reception since
the start of the current day.
• GET continues to be indicated even if an attempt at manual
receive fails after auto receive is successful.
Calibration Signal Reception
Precautions
• Auto reception can be performed while the watch is in the
Timekeeping Mode only.
• If the hands become misaligned for some reason, they may not
indicate the correct time, even if the time calibration signal is
received normally. If this happens, use the procedure under
“Adjusting the Home Positions” to adjust the home positions of the
hands and the date.
• Pressing any button while auto reception is in progress will cause
the watch to beep and signal reception to stop.
• Make sure you are within the range of the calibration signal
transmitter before performing the reception operation. Remember
that geographic contours, nearby buildings, seasonal conditions,
the time of day, can even 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 only. It
operates like a standard (non-radio controlled) watch outside of
the range of the receivable time calibration signal transmitters.
• When the watch is unable to receive the time calibration signal for
some reason, timekeeping accuracy is within ±20 seconds per
month.
• Strong electrostatic charge can cause timekeeping error.
• Signal reception is cancelled if the alarm starts to sound while it is
being performed.
• The watch’s calendar shows dates up to the year 2099.
Attempting a receive operation after that causes an error.
Receiving the Calibration Signal
There are two methods you can use to receive the time calibration
signal.
Auto receive (Reception is performed automatically at midnight,
1:00, 2:00, 3:00, 4:00 and 5:00 each morning.)
Manual receive (You initiate reception using a button operation.)
• When any auto receive is successful, further auto receive
operations for that day are not performed.
• Successful auto receive keeps timekeeping accurate.

To position the watch for optimum
reception
Remove the watch from your wrist and place it somewhere so its
right side (9 o’clock side, where the antenna is located) is facing a
