Operation Guide 4798
•Signal reception may not be possible at the distances noted below during certain times of the year or day. Radio interference also may cause problems with reception.
Mainflingen (Germany) or Rugby (England) transmitters: 500 kilometers (310 miles)
•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.
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 Time Zone, and whether standard time or Daylight Saving Time is selected for your Time Zone.
Note
•Auto receive is turned on whenever +0.0, +1.0, or +2.0 (+1.0, +2.0, or +3.0 while DST is turned on) is selected as the Home Time Zone.

You can use the stopwatch to measure elapsed time, cumulative elapsed time, and lap times. You also can input the distance of the course or a particular segment of the course of the race you are watching. That distance is used along with the elapsed time, cumulative elapsed time, or lap time measured by the watch to calculate and display the average speed for the course or segment.
•See “Average Speed” for more information.
•Never operate the stopwatch while operating any motor vehicle or while riding a motorcycle. Doing so is very dangerous and can cause an accident.
•Entering the Stopwatch Mode causes the second hand, the stopwatch minute hand and stopwatch 1/20 second hand to move to the 12 o’clock position.

calibration time is reached while an alarm is sounding or 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 14 minutes everyday when the |
time in the Timekeeping Mode reaches each of the calibration times. Avoid |
performing 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. |
To perform manual receive
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 Afor about two seconds until the watch beeps.
3. The second hand will move to R (READY) to indicate that the watch is setting up for time calibration reception.
•The display range of the stopwatch is 59 minutes, 59.99 seconds.
•The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.
•The stopwatch measurement operation continues even if you exit the Stopwatch Mode.
•All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C.

while actual reception is in progress.
• The hour and minute hands continue to keep time normally.
• Time calibration signal reception takes from two to seven minutes, but in some cases it can take up to 14 minutes. Take care that you do not perform any button operations or move the watch during this time.
• If reception is successful, the second hand will move to Y (YES). One minute later, the hands will move to the correct time.

To measure cumulative elapsed time
1.In the Stopwatch Mode, press B to start elapsed time measurement.
2.Press Bto stop elapsed time measurement.
3.Press Bagain to restart elapsed time measurement.
4.Press Bto stop elapsed time measurement.
•Repeat steps 3 and 4 as many times as required.
•Press Ato reset the stopwatch to zero.
Note
•To interrupt a receive operation and return to the Timekeeping Mode, press any button.
•If reception is not successful, the second hand will move to N (NO).
One minute later, the second hand will resume normal operation, without any adjustment of the hand setting.
•If the second hand is pointing to Y (YES) or N (NO), you can return to the Timekeeping Mode by pressing any button.

•Pressing A to display the current lap time also will start timing of the next lap. This means that the stopwatch does not maintain the total elapsed time or total cumulative time in this case.

The current receive result is cleared when the first auto receive operation is performed on the following day. This means Y (YES) indicates successful signal reception since the start of the current day.
•If you have adjusted the time or date setting manually, the second hand will indicate N (NO) here.
Average Speed
You also can input the distance of the course or a particular segment of the course of the race you are watching. That distance is used along with the elapsed time, cumulative elapsed time, or lap time measured by the watch to calculate and display the average speed for the course or segment.
The average speed that appears for an elapsed time, cumulative elapsed time, or lap time is calculated based on the times described below.
Elapsed time: Time from the point the stopwatch operation is started up until it was stopped.
Cumulative elapsed time: Total time from the point the cumulative elapsed time operation is started up until it was stopped. Does not include any time when the stopwatch operation was paused.
Lap time: Time of each particular lap.
•Never operate the stopwatch while operating any motor vehicle or while riding a motorcycle. Doing so is very dangerous and can cause an accident.
•For information about inputting a distance, see “To input a course or section distance”.
