Note
• When a calibration time is reached, the watch will receive the calibration
signal only if it is in either the Timekeeping Mode or World Time Mode.
Reception is not performed if a calibration time is reached while you are
configuring settings.
• 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 receive the signal easily.
• The watch takes from two to 14 minutes to receive the time calibration
signal whenever a calibration time is reached. Do not perform any button
operation within 14 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 current
time 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 displayed 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. The receiving indicator is displayed while an auto
or manual receive operation is in progress.

(Level 0)

(Level 3)
• 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 receive operations.
• Following reception of the time calibration signal and calibration of the
watch’s time setting, a “settings updated” indicator (
) will remain on the
display in all modes. The settings updated indicator (
) will not be
displayed if signal reception was unsuccessful or after you adjust the
current time setting manually.
• The settings updated indicator (
) appears only when the watch is able to
receive both time and date data successfully. It does not appear when only
time data is received.
• The settings updated indicator (
) indicates that at least one of the auto
calibration signal receive operations was successful. Note, however, that
the indicator disappears from the display each day at the start of the first
auto receive operation of the day.
To perform manual receive
1. Enter the Receive Mode.
2. Place the watch on a stable surface so its 12
o’clock side is facing towards a window.
3. Hold down A for about two seconds until RC!
appears on the display.
• 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.
• If the receive operation is successful, the
reception date and time appear on the display,
along with the
GET indicator.
The watch will enter the Receive Mode if you
press A or if you do not perform any button
operation for about one or two minutes.

Receive successful
• If the current reception fails but a previous
reception was successful, the display shows
the previous reception’s date and time, and the
ERR indicator. indicates that none of
the reception operations have been successful
during the current date.
The watch will enter the Receive Mode without
changing the time setting if you press A or if
you do not perform any button operation for
about one or two minutes.
Note
• To interrupt a receive operation and return to
the Receive Mode, press A.

• 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 A to toggle auto receive on (
ON) and
off (
OFF).
4. Press E to exit the setting screen.

About 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 reception schedule (calibration times)
depends on your currently selected Home City, and whether standard time or
Daylight Saving Time is selected for your Home City.
