Operation Guide 3140 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. This watch is designed to receive a time calibration signal late at night. Because of this, you should place the watch near a window as shown in the illustration when you take it off at night. Make sure there are no metal objects nearby. 12 o'clock or • Make sure the watch is facing the right way. • Proper signal reception can be difficult or even impossible under the conditions listed below. Inside or among buildings Inside a vehicle Near household appliances, office equipment, or a mobile phone Near a construction site, airport, or other sources of electrical noise Near high-tension power lines Among or behind mountains • Signal reception normally is better at night than during the day. • Time calibration signal reception takes from two to seven minutes. Take care that you do not perform any button operations or move the watch during this time. • The time calibration signal the watch will attempt to pick up depends on its current Home City code setting as shown below. Home City Codes and Transmitters Home City Code Transmitter Frequency HNL*, ANC*, YVR, LAX, YEA, DEN, MEX, YWG, CHI, MIA, YTO, NYC, YHZ, YYT Fort Collins, Colorado (the United States) 60.0 kHz LIS, LON, MAD, PAR, ROM, BER, STO, ATH*, MOW* Anthorn (England) 60.0 kHz * The areas covered by the HNL, ANC, ATH, and MOW city codes are quite far from the time calibration signal transmitters, and so certain conditions may cause problems with signal reception. Approximate Reception Ranges U.K. Signal 1,500 kilometers Anthorn U.S. Signal 2,000 miles (3,000 kilometers) 600 miles (1,000 kilometers) 500 kilometers Fort Collins U.K. signal transmitter approximate reception range as of April 2007 • Signal reception may not be possible at the distances noted below during certain times of the year or day. Radio interference may also cause problems with reception. Anthorn (England) transmitter: 500 kilometers (310 miles) Fort Collins (United States) transmitter: 600 miles (1,000 kilometers) • In April 2007, the U.K. signal transmitter was moved from Rugby to Anthorn, which resulted in a slight shift in the approximate reception range of the signal. The shift is so slight that there is virtually no change in the ability to receive the signal. • Even when the watch is within the reception range of a transmitter, signal reception may be impossible at times due to the effects of geographic contours, structures, weather, the season of the year, the time of day, radio interference, etc. Note that the signal becomes weaker at distances of approximately 500 kilometers from the transmitter, which means that the influence of the conditions listed above becomes even greater. 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. Your Home City HNL, ANC, YVR, LAX, YEA, DEN, MEX, YWG, CHI, MIA, YTO, NYC, YHZ, YYT Standard Time Daylight Saving Time LIS, LON Standard Time Daylight Saving Time MAD, PAR, ROM, BER, STO Standard Time Daylight Saving Time Standard Time ATH Daylight Saving Time MOW Standard Time Daylight Saving Time Auto Receive Start Times 1 2 3 4 5 6 Midnight 1:00 am 2:00 am 3:00 am 4:00 am 5:00 am 1:00 am 2:00 am 3:00 am 4:00 am 5:00 am Midnight * 2:00 am 3:00 am 4:00 am 5:00 am Midnight * 1:00 am * 2:00 am 3:00 am 4:00 am 5:00 am Midnight * 1:00 am * 3:00 am 4:00 am 5:00 am Midnight * 1:00 am * 2:00 am * 3:00 am 4:00 am 5:00 am Midnight * 1:00 am * 2:00 am * 4:00 am 5:00 am Midnight * 1:00 am * 2:00 am * 3:00 am * 4:00 am 5:00 am Midnight * 1:00 am * 2:00 am * 3:00 am * 5:00 am Midnight * 1:00 am * 2:00 am * 3:00 am * 4:00 am * * Next day 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 receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the calibration times. Avoid performing 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 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. • 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. Receiving indicator Weak (Level 0) Strong (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 D for about two seconds until RC! appears on the display. • Time calibration signal reception takes from two to seven minutes. Take care that you do not perform any button operations or move the watch during this time. Receiving indicator • 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 On/Off Status 1. In the Timekeeping Mode, press D to display the Last Signal screen. 2. Hold down A until the receiving indicator and current auto receive setting ( or ) start to flash. This is the setting screen. • 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 ( ) and off ( ). 4. Press A to exit the setting screen. • For information about city codes that support signal receive, see "To specify your Home City". To display the Last Signal screen In the Timekeeping Mode, press D to 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.
