To toggle between 12-hour and 24-hour timekeeping

In the Timekeeping Mode, press D to toggle between 12-hour timekeeping and 24-hour timekeeping.

With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for

times in the range of noon to 11:59 p.m. and the A (AM) indicator appears to the left of the hour digits for times in the range of midnight to 11:59 a.m.

With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without

any indicator.

The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is

applied in all other modes.

The A and P indicators are not displayed with the Timekeeping Mode time on the

Countdown Timer Mode and Dual Time Mode screens.

Daylight Saving Time (DST) Setting

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

• See “To measure elapsed time with lap times” (page E-16) and “To measure elapsed

time with split times” (page E-18) for more information about each type of measurement.

• You can perform elapsed time measurement starting from either the lap time screen

or the split time screen (pages E-16 and E-18). Whenever you enter the Stopwatch Mode, the screen (lap time or split time) that was displayed when you last exited the mode will appear first.

• During a stopwatch elapsed time operation, the upper display initially shows

minutes, seconds, and a 1/100-second value. This changes to hours, minutes, and seconds when the time in the upper display exceeds 60 minutes.

• The lower display initially shows hours, minutes, seconds, and a 1/100-second

value. This changes to hours, minutes, and seconds when the time in the lower display exceeds 10 hours.

The stopwatch lets you measure elapsed time, lap times, split times, and two finishes. Lap times and split times can be stored in memory.

• The display range of the stopwatch is 99 hours,

59 minutes, 59 seconds.

• All of the operations in this section are performed in the

Stopwatch Mode, which you enter by pressing C (page E-6).

Note

• “Lap time” is the time spent to cover a specific segment

of a race, such as one lap around a track. “Split time” is the time spent from the beginning of a race up to a

1/100 second

certain point.

• The stopwatch continues to run, restarting from zero

after it reaches its limit, until you stop it.

To toggle the Timekeeping Mode between DST and Standard Time

1. In the Timekeeping Mode, hold down A until the seconds start to flash, which indicates the setting screen.

2. Press C once and the DST setting screen appears.

3. Press E to record the time of the first split.

• The current split time appears in the lower display for

about eight seconds, as the total elapsed time, next lap time, and next split time continue to be timed internally by the watch. The split number of the displayed time appears in the upper display.

• After eight seconds, the ongoing lap time

measurement appears in the upper display and the ongoing elapsed time measurement appears in the lower display.

measurement re-appears in the lower display.

4. Repeat step 3 to record more lap times.

5. Press D to stop the stopwatch.

6. Press E to clear the stopwatch to all zeros.

• Lap numbers are incremented automatically starting

from 1 whenever you press E in step 3 of the above procedure. The maximum lap number is 99. Recording a lap after that causes the lap number count to restart from 00.

4. Repeat step 3 to record more split times.

5. Press D to stop the stopwatch.

6. Press E to clear the stopwatch to all zeros.

• Split numbers are incremented automatically starting

How stopwatch data is stored

The following table shows how stopwatch data is stored when you perform stopwatch button operations.

Stopwatch Button Operation Data Storage Description

From all-zeros, press D to start.

Press E to display lap/split time.

Press D to stop elapsed time measurement and then press

to reset.

Creates a new log. Stores the date the button was pressed, and the new log number.

Creates a new record with each button operation. Stores the lap and split times and total elapsed time at each point the button is pressed.

Resets the elapsed time to all zeros without recording data.

• See “Recall Mode” (page E-23) for details on how to recall time records from memory.

E-22

To recall stopwatch time records

1. In the Stopwatch Mode, check to make sure that the displays reset to all zeros (page E-16).

• If all zeros are not displayed, reset the stopwatch.

2. Use the E button to select either the lap time screen (to view lap time records) or the split time screen (to view split time records) (pages E-16 and E-18).

• To convert a lap time saved in the Stopwatch Mode to a split time, select the split

time screen.

3. Press the C button to enter the Recall Mode.

4. Use the A button to scroll through the log title screens from the newest to the oldest until the title screen of the log whose records you want to view is displayed.

5. Use D (forward) and E (back) to scroll through records in lap number sequence.

E-24

Memory Management

A new log is created each time you press D in the Stopwatch Mode to start a new elapsed time measurement operation. A log contains a log title screen, and records of all the lap or split times you record during the current elapsed time measurement operation.

• The capacity of the watch’s memory is 60 records.

• If you are adding records to a log when there are multiple logs in memory and

watch memory becomes full, adding another record causes the oldest log in memory and all of its records to be deleted automatically to make room for new records.

• Whether you will be able to view lap time records or split time records will depend

on the screen you selected in step 2, above.

Use the Recall Mode to recall and delete logs and records you stored in the Stopwatch Mode. You can use the Recall Mode to view both lap and split time records.

• When you enter the Recall Mode, the newest log

recorded in the Stopwatch Mode will appear first. If there are no logs in memory, display.

• You can use the Recall Mode to check memory data

even while a stopwatch elapsed time measurement operation is in progress. However, the time data that is currently being measured will not appear in the Recall Mode.

• You can convert a lap time saved in the Stopwatch

Mode to a split time (page E-24).

2. Hold down D and E until stops flashing on the display.

• This deletes the log and all the records inside it.

• Deleting a single log slides all newer logs (ones with higher log numbers) upwards

to fill the empty space. This cause the log numbers of all the newer logs to be reduced by 1. If there are six logs currently in memory (numbered 01 through 06) and you delete log 03, the numbers of logs that previously were numbered 04, 05, and 06 will change to 03, 04, and 05.
