GENERAL GUIDE

Press C to change from mode to mode.

Holding down C for a few seconds in any mode enters the Stopwatch Mode. Holding down C in the Stopwatch Mode changes to the Timekeeping Mode.

There are two stopwatches in the Stopwatch Mode. Press C while in the Stopwatch Mode to toggle between them. See “STOPWATCH MODE” for more information.

At any time except while making settings, press D to illuminate the display for about 4 seconds.

3.While the seconds digits are selected (flashing), press D to reset the seconds to 00. If you press D while the seconds count is in the range of 30 to 59, they are reset to 00 and 1 is added to the minutes. If the seconds count is in the range of 00 to 29, the minutes count is unchanged.

4.While any other digits (besides seconds), are selected (flashing), press D to in- crease the number or B to decrease it. Holding down either button changes the

digits at high speed.

The date can be set with the range of January 1,1995 to December 31, 2039.

5.After you are set the time and date, press A to return to the Timekeeping Mode.

The day of the week is automatically set in accordance with the date.

If you do not operate any button for a few minutes while a selection is flashing, the

flashing stops and the watch goes back to the Timekeeping Mode automatically.

When the time shown on the display does not match the analog setting, see “H-SET MODE” to correct the analog setting.

Single Stopwatch

The Single Stopwatch is a standard stopwatch that measures elapsed time and lap times.

To measure elapsed time with the Single Stopwatch

1.Press B to start timing.

2.Press B again to stop timing.

You can repeat steps 1 and 2 as many times as you like.

3. Pressing A while timing is stopped resets the display to all zeros.

To measure lap times with the Single Stopwatch

1.Press B to start timing.

2.Pressing A while an timing operation is in progress displays the lap time in the upper part of the display and the lap number in the lower part. This information

remains displayed for about four seconds, after which the elapsed time display returns.

You can repeat step 2 as many times as you like.

3.Press B to stop timing.

4.Pressing A while timing is stopped resets the display to all zeros.

The final time on the display when you press B to stop timing is not stored into memory as a lap time. If you want to save the final time, press A and then B.

ABOUT THE BACKLIGHT

Hold down D to illuminate the display for about 4 seconds. The backlight is dis- abled while an input screen (with a flashing setting) is on the display.

The backlight of this watch employs an electro-luminescent (EL) light, which loses its illuminating power after very long term use.

Frequent use of the backlight shortens the battery life.

The watch emits an audible sound whenever the display is illuminated. This does not indicate malfunction of the watch.

The illumination provided by the backlight may be hard to see when viewed under direct sunlight.

The backlight automatically turns off whenever an alarm sounds.

STOPWATCH MODE

The Stopwatch Mode automatically saves the best five lap times in memory, along with lap numbers. You can later recall the saved data using the “RESULT MODE” . The Stopwatch Mode provides you with the following types of stopwatch capabilities.

Single Stopwatch

This is a standard stopwatch that measures elapsed time and lap times.

Dual Stopwatch

This stopwatch lets you measures the times of two cars or runners at the same time.

Selecting the Stopwatch Type

While in the Stopwatch Mode, press C to toggle between the Single Stopwatch and Dual Stopwatch. Note that the C button is disabled while a stopwatch timing operation is in progress.

Depending on your watch model, the stopwatch display indicators may show CAR1 and CAR2 or STW1 and STW2.

Single Stopwatch

Dual Stopwatch

Dual Stopwatch

Use the Dual Stopwatch to measure the times of two cars or runners at the same time. You can also produce lap times for both and determine the difference between them.

The Dual Stopwatch is designed to time two runners or cars starting or passing at different times. Accurate measurement is not possible when both start or pass at the same time or close to the same time.

To use the Dual Stopwatch

1.Press B to start timing of the first starter, which appears in the upper part of the display.

2.Press A to start timing of the second starter, which appears in the lower part of the display.

3.When the first starter passes the timing points, press B.

4.When the second starter passes the timing points, press A.

The difference between the two times appears on the display for about four sec- onds. After that, each lap time appears for about four seconds.

If the time of the second starter is faster than that of the first, the time difference is displayed as a negative value.

If the time difference is 10 minutes or more, -- -- -- is displayed in place of the time.

If the times being compared are from different laps, the time difference is shown without a plus or minus indication.

Hold down A or B to stop timing. The final time on the display when you hold down A or B to stop timing is not stored into memory as a lap time. If you want to save the final time, press A or B, and then hold down A or B to stop timing.

Stopwatch type indicator

RESULT MODE

Use this mode to view the best five lap times and lap numbers. Lap times are stored by either a Single Stopwatch or Dual Stopwatch operation. Current memory contents are always the results produced by the last stopwatch operation.

If you know the length of a lap, you can input it and calculate the speed as well. You can input or change the length either before or after the timing operation.

To input the length of a lap

1.Hold down A until the kilometers digits start to flash on the display

2.Each press of C moves the input position between the kilometers digits and the decimal digits.

3.After inputting the value you want, press A to save it.

If you do not operate any button for a few minutes while a selection is flashing, the flashing stops and the watch goes back to the Result Mode automatically.
