To specify a distance value
|
|
| 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. |
|
|
| 2. Hold down Afor about three seconds until the current |

3. Press Cto 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
• 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.
Split Time
A split time reading shows the time elapsed since the beginning of the current time measurement.
• If you want the watch to calculate the speed of the race, specify the race distance for the distance setting.
• 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 | |
Split time | the total race distance, and so they will not indicate | |
actual intermediate split speeds. | ||

To set up the stopwatch to take split time readings
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.
2.Make sure that SPL (split times) is shown in the lower digital display.
•If LAP (lap times) is displayed, press A to toggle it to SPL.
How speed is indicated
To perform a split time measurement
Segments OVER (100 unit)
Speed hand (Up to 100)
1000 indicator
•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
•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.

DStop ➝ A Reset
*The split time is released automatically if you do not press Awithin about 12 seconds.
•You can press Ato take split readings as many times as you like.
•The stopwatch continues elapsed time measurement internally while a split time reading is displayed.
•Pressing A while a split time is displayed will switch back to normal elapsed time measurement. The elapsed time will appear in the lower digital display.
•You also could press Dto stop elapsed time measurement instead.
•Pressing D to stop elapsed time measurement displays the time (and speed if a distance is specified) of the final split (which is the overall elapsed time).
Upper display segments: Indicate 700.

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.
•Make sure that LAP (lap times) or SPL (split times) is shown in the lower digital display.
•If you need to reset the stopwatch to all zeros, press A.
2.You can toggle between LAP (lap times) and SPL (split times) by pressing A.

Elapsed Time Measurement
Use the following procedure to measure elapsed time, without taking lap time or split time readings.
To perform elapsed time measurement
Select split time (SPL) measurement and then perform the following button operations.
DStart ➝ D Stop ➝ AReset
•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 Dagain to restart from the point where you left off.
Lap Time
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. | |
Lap time | 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. |
To set up the stopwatch to take lap time readings
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.
2.Make sure that LAP (lap times) is shown in the lower digital display.
•If SPL (split times) is displayed, press Ato toggle it to LAP.
