Operation Guide 2911

•This watch is designed to receive the time calibration signal transmitted from Rugby, England and the signal from Mainflingen, Germany.

Reception Ranges

Rugby

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 is 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 Receive Troubleshooting” if you experience problems with time calibration signal reception.

About Auto Receive

When auto receive is turned on, the watch attempts to receive the time calibration signal automatically up to six times. The start times of the auto receive operations depend on the current Home City and DST settings.

•If all of the first three reception operations fail, the watch automatically performs a fourth receive operation.

•If any of the remaining receive operations (4, 5, or 6) is successful, any remaining receive operations are skipped.

•Auto receive is performed in accordance with the Timekeeping Mode time.

LON	Standard Time	Midnight	1:00 am	2:00 am	3:00 am	4:00 am	5:00 am

PAR	Daylight Saving Time	2:00 am	3:00 am	4:00 am	5:00 am	Midnight	1:00 am
							next day

Note

•Auto receive works only while the watch is in the Timekeeping Mode or World Time Mode. Auto receive is not performed if an auto receive time is reached while an alarm is sounding, while a countdown timer operation is in progress, or if a setting screen (a screen with a flashing setting) is on the display.

•Auto receipt 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.

•When auto receive is turned on, the watch receives the calibration signal for two to six minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Do not perform any button operation within six 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 is actually the correct time.

•If more than one auto receive is successful, the watch uses the data from the last successful receive to adjust settings. When only one reception is successful, the watch uses the data of the successful reception.

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 receive operations.

•Following reception of the time calibration signal and calibration of the watch’s time setting, the Level 4 receiving indicator will remain on the display in all modes. The Level 4 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

•The Level 4 receiving indicator is displayed 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 Level 4 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 4 receiving indicator disappears from the display each day when the second auto receive operation of the day is performed.

To perform manual receive

Receiving indicator	1. Place the watch on a stable surface so its top (12
	o’clock side) is facing towards a window.
	2. In the Timekeeping Mode, hold down Dfor about two
	seconds until the watch beeps.
	• Release Dand the message RC! appears to indicate
	that signal reception has started.
	• Time calibration signal reception normally takes from
	two to six minutes, but in some cases it can take as long
	as 12 minutes. Take care that you do not perform any
	button operations or move the watch while time
	calibration signal reception is in progress.

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

Note

•To interrupt a receive operation and return to the Timekeeping Mode, press D.

•If the receive operation 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.

Configuring Auto Receive Settings

You can use the procedure in this section to configure the watch to receive the signal of a specific transmitter, or to receive automatically from the transmitter whose signal is strongest. You can also turn off auto receive, if you want.

•Note that you can perform the following procedure only when LON, BER, or PAR is selected as your Home City.

3.Use D to cycle through the settings shown below, until the one you want to use is displayed.

DCF OFF

qvtA : Auto receive on. The watch selects the transmitter whose signal is strongest automatically. Signal reception can take up to 12 minutes when this option is selected.

DCF : Auto receive on for reception of the Mainflingen signal.

MSF : Auto receive on for reception of the Rugby signal.

OFF : Auto receive off.

• For details about transmitters, see “Transmitters”.

4.Press Ato exit the setting screen.

•To return to the Timekeeping Mode from the last signal screen, press D.

•For information about city codes that support signal reception, see “To set your Home City”.

Note

•Manual receive operations are also performed based on the transmitter setting (qvtA, DCF, MSF) you select above.

•If auto receive is turned off, performing a manual receive operation receives the signal that is strongest automatically.

To display the Last Signal screen

In the Timekeeping Mode, press Dto display the Last Signal screen (indicated by GET). The Last Signal screen shows the date and time of the last successful time calibration signal reception.
