Operation Guide 3017

•Signal reception is normally better at night than during the day.

•Time calibration signal reception takes from two to six minutes, but some cases it can take as long as 12 minutes. Take care that you do not perform any button operations or move the watch during this time.

•When within range of the applicable transmitter, this watch can receive either the Germany (Mainflingen) or England (Rugby) time calibration signals.

See “Transmitters” for more information.

Reception Ranges

1,500 kilometers

Rugby
500 kilometers	Mainflingen

•This watch is designed to receive the time calibration signal transmitted from Mainflingen, Germany and the signal from Rugby, England. Signal reception is possible within the area represented by a circle with a radius of about 1,500 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.

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.

Note

•Auto receive is turned on whenever LIS, LON, BCN, MAD, PAR, MIL, ROM, BER, STO, or ATH is selected as the Home City code.

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 while a setting screen (a screen with a flashing setting) is on the display.

•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.

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

•Calibration signal reception is disabled while a countdown timer operation is in progress.

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.

Weak	Strong
(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, the Level 3 receiving indicator will remain on the display in all modes. The Level 3 receiving indicator will not be displayed if signal reception was unsuccessful or after you adjust the current time setting manually.

•The Level 3 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 3 receiving indicator indicates that at least one of the auto calibration signal receive operations was successful. Note, however, that the Level 3 receiving indicator is cleared from the display when the first auto receive operation of the day is performed.

To perform manual receive

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 RC! appears on the display.

• Time calibration signal reception takes from two to six minutes, but some cases it can take as long as 12 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 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.

•Calibration signal reception is disabled while a countdown timer operation is in progress.

To turn auto receive on and off
