Calibration Signal Reception
Precautions
• Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• When a time calibration signal is received, the watch corrects its
digital time setting first, and then adjusts the analog time setting
accordingly. In order to ensure that the analog time matches the
digital time, make sure you adjust the analog time to match the
digital time before signal reception is performed.
• Pressing any button while auto reception is in progress will cause
the watch to beep and then exit the receive operation.
• 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.
Configuring Auto Receive Settings
Use the procedure below to turn auto receive of the time
calibration signal on or off. When TYO (Tokyo) is selected as your
Home City, you can also specify the transmitter selection mode,
"
which controls which Japanese transmitter signal should be used
for time calibration.
• For information about selecting your Home City, see "Configuring
Home Time Settings".
• The initial factory default settings for auto receive are Home City =
TYO (Tokyo); Auto Receive = On; Transmitter = AUTO
• The following procedure can be performed only when TYO, LAX,
DEN, CHI, or NYC is selected as the Home City.
❚ To configure auto receive settings
1.
In the Timekeeping Mode,

• This watch is designed to adjust its current time setting in
accordance with the calibration signal transmitted in Japan and
the United States 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 adjust its time signal using the
calibration signal for some reason, timekeeping accuracy is within
±15 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.
