allow better signal reception.

• After signal reception is complete, the display of the watch changes to the Last

Signal screen.

Time Calibration Signal Reception

This watch is designed to pick up a time calibration signal and update its time setting

in accordance with the signal. There are two different methods you can use to receive

the signal: Auto Receive and Manual Receive. With Auto Receive, the watch

automatically receives the calibration signal three times each day and makes

appropriate adjustments. With Manual Receive, you perform a specific button

operation to receive the calibration signal.

Before performing a signal receive operation, remove the watch from your wrist and

position it as shown in the illustrations below.

• If your watch has a resin band, pass the end of the band through the band loop and

place the watch on a stable surface.

Pass through band loop.

Note

• If you are using the time calibration signal to set the time for this watch, be sure to

correctly set your Home City. Otherwise, there is the chance that the watch will not

set the correct time. See “Setting the Time and Date Manually” for details.

• Note that signal reception is possible only when the watch is within range of a time

calibration signal transmitter, and BER, PAR, LON, or ATH is selected as the Home

City code.

• See “City Code Table” for a complete list of available city codes.

• The current time setting in accordance with the time calibration signal takes priority

over any time settings you make.

• Auto receive is turned on when the watch is shipped from the factory.

• See the information under “Time Calibration Signal Reception” if you experience

problems with time calibration signal reception.

To perform manual time calibration signal reception

1. Place the watch on a stable surface so its top (12 o'clock side) is facing in the

general direction of the signal transmitter.

• Note that signal reception is poor if the watch is on its back or side.

2. In the Timekeeping Mode, hold down D for about two

seconds until the watch beeps.

• Release D and the message RC! appears to indicate

that signal reception has started.

• Time calibration signal reception takes from two to six

minutes. Take care that you do not move the watch

during this time.

• After signal reception is complete, the display of the

watch changes to the Last Signal screen.

• The receive indicator indicates that the time calibration

reception attempt was successful.
