• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without the PM indicator (P).

• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all other modes.

1. In the Timekeeping Mode, hold down A for about three

seconds until the currently selected city code flashes in the upper digital display. This is the setting mode.

2. Press C. This will display the DST setting screen.

3. Use D to toggle the DST setting on (on) and off (OFF).

Stopwatch

Upper display segments

Speed hand

Important!

• Check to make sure that the speed hand is not moving before you perform any Stopwatch Mode button operation.

Specifying a Distance Value

You can use the procedure below to specify a distance value, if you want. If you specify a distance value, the watch will calculate and indicate speed for certain stopwatch operations.

• The distance value represents kilometers, miles, or any other distance unit you want. Specifying a distance value of 10.0, for example, can mean 10.0 kilometers or 10.0 miles.

• No speed calculation is performed when 0.0 is specified as the current distance valu e.

• For lap time readings, you can specify either the lap distance (when all the laps are the same distance) or the total race distance.

• For split time readings, you can specify the total race distance only. Though the watch will indicate a speed each time you take a split reading, they will be based on the total race distance, and so they will not indicate actual intermediate split speeds.

You can use the stopwatch to measure elapsed time, lap times and split times. If you specify a distance value, the stopwatch also will calculate and display speeds.

• The digital display range of the stopwatch is 99 hours, 59 minutes, 59.999 seconds. The stopwatch continues to run until you stop it. If it reaches the above limit, it will restart the time measurement from zero.

• The stopwatch operation continues even if you exit the Stopwatch Mode. If you exit the Stopwatch Mode while a stopwatch operation is in progress, the segments along the top of the upper digital display (upper display segments) will indicate the seconds of the current time. Each segment represents one second. This is to let you know that a stopwatch operation is in progress.

• All of the operations in this section are performed in the Stopwatch Mode, which you enter by pressing C.

Time Measurement

You need to specify either lap time or split time measurement before you start a stopwatch operation.

• If you want to measure total elapsed time, select split time measurement.

To specify lap time or split time readings

1. In the Stopwatch Mode, make sure the stopwatch is stopped and reset to all zeros.

Elapsed Time Measurement

Use the following procedure to measure elapsed time, without taking lap time or split time readings.

• If you have a distance value specified for the current elapsed time measurement, the

upper display segments and speed hand will indicate the speed when you press D to stop the elapsed time operation.

• After pressing D to stop an elapsed time operation, you could press D again to

restart from the point where you left off.

1. In the Stopwatch Mode, make sure the stopwatch is stopped and reset to all zeros.

• If you need to reset the stopwatch to all zeros, press A.

Hold down A for about three seconds until the current distance value setting flashes in the lower digital display.

• This is the distance value setting mode.

3. Press C to move the flashing between the values on the left side and right side of the distance value decimal point.

4. While a distance value is flashing, use D (+) and B (–) to change it.

• You can specify a distance value in the range of 0.1 to

99.9.

5. After specifying the distance value you want, press A to exit the setting mode.

• While an elapsed time measurement operation is being

performed in the Stopwatch Mode, the watch will indicate a speed value, which is calculated based on the distance you specified and the elapsed time. The speed value is indicated as described below. Speed hand: Up to 100 Upper display segments: 100 unit A 1000 indicator points to 1000 (located to the right of the upper display segments) when the speed value exceeds 1000.

• The speed hand indicates speed values less than 100.

Only even-numbered values are indicated.

• Speed can be indicated from 0 to 1998. OVER is

indicated by the speed hand when the speed exceeds

1998.

Example:

When the speed value is 1,740. Speed hand: Indicates 40. Upper display segments: Indicate 700. 1000 indicator: Displayed

A lap time reading shows the time elapsed since the last lap time reading was taken.

• If you want the watch to calculate the speed of each lap

(when all of the laps are the same distance), specify the lap distance for the distance setting.

• If you want the watch to calculate the speed of the entire

race, specify the race distance for the distance setting. A speed will be indicated each time you take a lap reading, but these lap speeds will not indicate actual speed of the entire race.
