*This hand rotates and indicates the second count during the first 60 seconds.

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 a motor vehicle. Doing so is very dangerous and can cause an accident.

•Entering the Stopwatch Mode causes the stopwatch second hand, the upper right dial hand and center dial hand to move to the 12 o’clock position.

•You can start elapsed time measurement with the stopwatch while the watch is in the Stopwatch Mode or the Timekeeping Mode.

Setting the Month

•The display range of the stopwatch is 59 minutes, 59.95 seconds.

•The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.

3.Press Bto stop elapsed time measurement.

•You can restart and stop elapsed time measurement as many times as you like by pressing B.

•The center dial hand rotates during the first 60 seconds only, and then stops. When elapsed time measurement is stopped (by pressing B), the center dial hand jumps to the 1/20 second indication (which is kept internally).

•Stopping a timing operation will cause the stopwatch second hand to stop at the elapsed time seconds position. It will remain there if there is no distance value input. If a distance value is input, the stopwatch second hand will then move to average speed indication after about two seconds. After that it will move back to the elapsed time second position.

•After you are finished measuring elapsed time, press Dto reset the stopwatch to all zeros.

•To return to the Timekeeping Mode, press D while the stopwatch is reset to all zeros.
