• Make sure the watch is facing the right way.
• Proper signal reception can be difficult or even impossible under the conditions
listed below.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to
six times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. For more information, see “About Auto Receive”.
• Manual Receive
Manual receive lets you start time calibration signal reception with the press of a
button. For more information, see “To perform manual receive”.
Important!
• When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side facing towards a window.
Make sure there are no metal objects nearby.

• Signal reception is normally better at night than during the day.
• Time calibration signal reception takes from two to seven minutes, but in some
cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.
Reception Ranges

1,500 kilometers
500 kilometers
• At distances further than about 500 kilometers from a transmitter, signal reception
may not be possible during certain times of year or times of day. Radio interference
may also cause problems with reception.
• Even when the watch is within the reception range of the transmitter, signal
reception will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
• See the information under “Signal Reception Troubleshooting” if you experience
problems with time calibration signal reception.

Note
• Auto receive is performed only if the watch is in the Timekeeping Mode or World
Time Mode when one of the calibration times is reached. It is not performed if a
calibration time is reached while an alarm is sounding, or while you are configuring
settings (while settings are flashing on the display).
• When a reception starts, the second hand will move at high speed to the 12 o’clock
position where it will stop until the reception is complete.
• Auto receive of the calibration signal is designed to be performed early in the
morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed for the night, remove the watch from your wrist, and put it in a
location where it can easily receive the signal.
• When auto receive is turned on, the watch receives the calibration signal for two to
seven minutes everyday when the time in the Timekeeping Mode reaches each of
the calibration times. Do not perform any button operation within seven minutes
before or after any one of the calibration times. Doing so can interfere with correct
calibration.
• Remember that reception of the calibration signal depends on the time kept in the
Timekeeping Mode. The receive operation will be performed whenever the display
shows any one of the calibration times, regardless of whether or not the
Timekeeping Mode time actually is the correct time.
About the Receiving Indicator
The receiving 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.
Receiving indicator
Weak
(Level 1)
Strong
(Level 4)
• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.
• Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal reception.
• The Level 4 receiving indicator indicates that at least one of the auto calibration
signal receive operation was successful. Note, however, that the Level 4 receiving
indicator is cleared from the display when the first auto receive operation of the day
is performed.
• The Level 4 receiving indicator appears on the Timekeeping Mode’s Receiving
Indicator and Seconds Count screen only. The Level 4 receiving indicator is not
displayed if signal reception was unsuccessful or after manual adjustment of the
current time setting.
To perform manual receive
1.Place the watch on a stable surface so its 12 o’clock
side is facing towards a window.
2.In the Timekeeping Mode, hold down D for about two
seconds until the watch beeps.
3.Release D and RC flashes to indicate that signal
reception has started.
• When a reception starts, the second hand will move at
high speed to the 12 o’clock position where it will stop
until the reception is complete.
• Time calibration signal reception normally takes from two to seven minutes, but in
some cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.
• After signal reception is complete, the display of the watch changes to the last signal
screen.
Note
• To interrupt a reception and return to the Timekeeping Mode, press D.
• If the reception is unsuccessful, the message
ERR 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
ERR screen to the normal timekeeping
screen by pressing D.
To turn auto receive on and off
1.In the Timekeeping Mode, press D to display the Last
Signal screen.
2.Hold down A until the current auto receive setting (
ON
or
OF
) starts to flash. This is the setting screen.
• The second hand will move at high speed to the 12
o’clock position, where it will stop.
• Note that the setting screen will not appear if the
currently selected Home City is one that does not
support time calibration reception.
3.Press D to toggle auto receive on (
ON
) and off (
OF
).
4.Press A to exit the setting screen.
• The second hand will advance at high speed to the correct position in accordance
with the digital time seconds count, and resume normal movement from there.
• For information about city codes that support signal reception, see “To set your
Home City”.

About Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to six
times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. The start times of the auto receive operations depend
on the current Home City and DST settings.
