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.

•Make sure the watch is facing the right way.

•Proper signal reception can be difficult or even impossible under the conditions listed below.

•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
Anthorn
500 kilometers	Mainflingen

• 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.

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.

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	Strong
(Level 1)	(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

Receiving indicator	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 Dfor 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

On/Off status	1. In the Timekeeping Mode, press Dto display the Last
	Signal screen.
	2. Hold down Auntil 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”.
