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 you 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.

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 a city code that supports signal
reception is selected as the Home City code.
• 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 A for about
two seconds until the watch beeps.
• Release A and the message receiving 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 calibration
Receive indicator
time reception attempt was successful.
Note
• To interrupt a receive operation and return to the Timekeeping Mode, press
A.
• If the receive operation is unsuccessful, the message ERROR! appears on
the display for about one or two minutes. After that, the watch returns to the
Timekeeping Mode.
• You can also change from the Last Signal or ERROR! screen to the normal
timekeeping screen by pressing A.
About the Receive Indicator
The receive indicator shows the strength of the calibration signal being received.
For best reception, be sure to keep the watch in a location where signal strength is
strongest.
Weak
• Even in an area where signal strength is strong, it takes about 10 seconds for
signal reception to stabilize enough for the receive indicator to indicate signal
strength.
• Use the receive indicator as a guide for checking signal strength and for
finding the best location for the watch during signal receive operations.
• The receive indicator remains on the display in all modes following reception
of the time calibration signal and calibration of the watch's time setting. The
receive indicator does not appear if signal reception was unsuccessful or
after manual adjustment of the current time setting.
