To start an elapsed time operation while in the Timekeeping Mode

1.In the Timekeeping Mode, press B to start elapsed time measurement.

•Elapsed time measurement will start internally when you press B, but timing will not appear for about one second.

•The elapsed time measurement will not start if you press Bin the Timekeeping Mode while either of the following conditions exists.

While an alarm is sounding

While the watch is changing from one date to the next (at midnight)

2.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 D to reset the stopwatch to all zeros.

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

operation.

2. Press Dto display the current lap time.

• Each press of Ddisplays the current lap time up to

that point.

• The lap time will remain displayed for about two

• To disable speed display, specify a distance value of 0.0.

seconds.

• Pressing Dto 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 stopwatch will continue to time the next lap

internally, even while the current lap time is displayed.

When the alarm is turned on, the alarm sounds when the alarm time is reached.

•Whenever you enter the Alarm Mode, the stopwatch second hand will move to the ALM position. The center dial hand will move to the alarm’s current ON/OFF status while the hour, minute and 24-hour hands indicate the current alarm time setting.

•All of the operations in this section are performed in the Alarm Mode.

•If a distance value is input, performing a lap time operation will cause the stopwatch second hand to stop at the current lap time for about two seconds. The stopwatch second hand will then move to the speed indication of the lap for about two seconds. After that it will move to the ongoing elapsed time operation position.

3.Press B to stop the stopwatch.

•This will cause the final lap time to appear on the display.

•Press Dto reset the stopwatch.

24-hour hand

Center dial hand

To set an alarm time

1.In the Alarm Mode, hold down Afor about three seconds until the watch beeps and the center dial hand moves to ON (alarm on).

•This is the setting mode.

•Setting the alarm time causes the alarm to turn on automatically.

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

•The initial factory default setting for the distance value is 1.0.

•For information about inputting a distance, see “To specify a course or section distance”.

Average Speed Indication

2.Use D(+) and B(–) to change the alarm time setting.

• Each press of either button changes the setting by one minute.

3.After setting the alarm time, press A to exit the setting mode.

•As you set the alarm time, take care to ensure that the 24-hour hand also is at the correct position.

Alarm Operation

The alarm tone sounds at the alarm time for 10 seconds, regardless of the mode the watch is in.

•Alarm operations are performed in accordance with the Timekeeping Mode time.

•Pressing any button stops the alarm tone operation.

To toggle an alarm on and off

In the Alarm Mode, press A to toggle the alarm setting indicated by the center dial hand ON or OFF.

Center dial hand

The stopwatch second hand will indicate the average speed value after you stop an elapsed time measurement or display a lap time. The center dial hand points to SPEED (SPD) while the average speed is being indicated.

Stopping an Elapsed Time or Cumulative Elapsed Time Measurement

Two seconds after you stop an elapsed time measurement operation by pressing B, the stopwatch second hand will indicate the speed for two seconds. After that, the stopwatch second hand will move back to the elapsed time seconds position.

Lap Time Measurement

Two seconds after you stop a lap time measurement

other indicator settings correctly, you can adjust the “home positions” of the hands manually to correct them.

To adjust the home positions

1. In the Timekeeping Mode, as you hold down A, hold

	• This indicates that the watch is in the time and day
	home position adjustment mode.
	• The center dial hand is in the proper home position if
	it moves to “0”. If it doesn’t, use Dto move the center
	dial hand to “0”.

operation by pressing D, the stopwatch second hand will indicate the speed for two seconds. After that, the stopwatch second hand will move to the ongoing elasped time operation.

•If the value you input for the distance was in kilometers, the indicated speed values will show kilometers per hour. If the value you input was in miles, it will show miles per hour. Note that the watch does not have a setting for specifying kilometers or miles.

•The average speed is indicated as a value from 0 to 350, in increments of 10. The ones digit is rounded off.

•Either of the following will cause the stopwatch second hand to indicate OVER, which indicates that speed cannot be calculated.

When the speed calculation produces a value greater than 350

When a displayed elapsed time or cumulative elapsed time is 60 minutes or greater

When a displayed lap time is 60 minutes or greater (Average speed calculation will resume when timing of the next lap is performed.)

2.After confirming that the center dial hand and stopwatch

second hand are both at the proper home positions, press C.

This will switch to hour hand and minute hand home position adjustment.

•The hour hand and minute hand are at their proper home positions if they both move to 12 o’clock, and if

the 24-hour hand is pointing at hour 24. If the hands are not positioned correctly, use D(+) and B (–) to move all three hands to their proper home positions.

•The 24-hour hand moves in accordance with the hour, minute, and second settings. As you set the time, take care to ensure that the 24-hour hand also is at the correct position.
