To position the watch for optimum
reception
Remove the watch from your wrist and place it somewhere so its
top (12 o’clock side, where the antenna is located) is facing
approximately in the direction of the signal transmitter. Keep the
watch away from metal objects.

• Orienting the watch so it is sideways to the transmitter makes it
more difficult to receive the signal.
• Do not move the watch while it is receiving the calibration signal.
❚
Time Required for Reception
A calibration signal receive operation takes anywhere from about
two to five minutes.
• Note that when “AUTO” (Auto Select) is specified as the
transmitter selection mode, signal reception can take up to
12 minutes.
• See “Configuring Auto Receive Settings” for more information.

To perform manual receive
In the Timekeeping Mode, hold
down the
DD

When reception is successful
The watch terminates reception and adjusts the current time. Next
it beeps and then displays the date and time that the adjustment
was performed.
• The watch will return to the Timekeeping Mode screen if you
press the D button or if you do not perform any operation for
about two or three minutes.
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 screen if you
press the D button or if you do not perform any operation for
about two or three minutes.

Receive Indicator
The receive indicator cycles from
“Unstable” through “Stable” as
shown below while reception is in
progress. How far it cycles depends
on the signal strength. Keep the
watch in a location where reception
is stable while reception is in
progress.

determine the best location for signal reception.
• Note that weather, the time of day, surroundings, and other
factors can all affect reception.

Configuring Auto Receive Settings
Use the procedure below to turn auto receive of the time
calibration signal on or off. When TYO (Tokyo) or SEL (Seoul) 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, SEL,
NYC, CHI, DEN, or LAX is selected as the Home City.

(60kHz), whichever is strongest.
• J40
Auto receive turned on for the Mt. Otakadoya signal (40kHz).
• J60

Calibration Signal Reception
Precautions
• Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
• Reception cannot be performed while Timer Mode countdown is in
progress.
• 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.
