Configuring Auto Receive Settings
Use the procedure below to turn auto receive of the time

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.

Reception Error (ERR Indicator)
The watch does not adjust its current time setting, and displays
“ERR” when signal reception is unsuccessful for some reason.
• The watch will return to the Timekeeping Mode automatically if
you do not perform any operation for about one or two minutes.
❚
Receive Mark and Receive Indicator
The receive mark and receive indicator
cycle from “Unstable” through “Stable”
as shown below while reception is in
progress. How far they cycle depends
on the signal strength. Keep the watch
in a location where reception is stable
while reception is in progress.
Unstable Stable
• Even under optimum reception conditions, it can take about 10
seconds for reception to stabilize.
•
Use the receive mark and receive indicator to check reception
status and to determine the best location for signal reception.
• Note that weather, the time of day, surroundings, and other
factors can all affect reception.

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.
• 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. 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.
