Mode time

1/100 second

The 1/100-second stopwatch can measure elapsed time and lap/split times. The stopwatch uses the basic data you input and a pacer signal to calculate the distance you cover while jogging or running. Stopwatch times and your distance are also stored in memory.

•The stopwatch measurement operation continues even if you exit the Stopwatch Mode.

•Exiting the Stopwatch Mode while a lap/split time is frozen on the display clears the lap/split time and returns to elapsed time measurement.

•Stopwatch measurements are performed in the Stopwatch Mode, which you enter by pressing C.

How the Stopwatch Works

There are two ways you can use the stopwatch: to measure elapsed time and lap/split times like a standard stopwatch (see “To measure times with the stopwatch”), and to keep track of the distance you cover while jogging or running. In order to use the stopwatch to keep track of distance, you must first perform the steps listed below.

1.Set your basic data. See “Basic Data”.

2.Turn on the pacer signal. See “To turn the pacer signal on and off”.

Note

•In order to obtain accurate distance calculations, you must set accurate basic data and keep your exercise pace in accordance with the pacer signal emitted by the watch.

•Use the Recall Mode to view data stored in memory.

•You can view distance covered data only by recalling it in the Recall Mode. It does not appear on the Stopwatch Mode screen.

Note		Split

•Pressing Dto perform a lap/split time operation freezes the lap/split time at that point on the display for about eight seconds. After that, the display returns to normal stopwatch time measurement.

•During a stopwatch time measurement operation, the upper part of the display shows the hour digit and the current lap/split number, the center part shows the current split time, and the lower part shows the current lap time.

•When the pacer signal is turned on, it sounds for the first 30 seconds after you start

a stopwatch time measurement operation. After that, the pacer signal sounds for 30 seconds whenever you press B.

•If the pacer signal does not sound even though you have it turned on, press Bto change the positions of the lap time and split time on the display. This should cause the pacer signal to sound.

Selecting the Stopwatch Screen Format

The following shows how you can control the position of the lap time and split time on

the stopwatch screen.

•The Lap/Split indicator uses arrows to indicate the location the lap time and split (elapsed) time.

•When you first start a stopwatch operation by pressing A, both the center part and the lower part of the display show minutes, seconds, and 1/100 second. Whenever the time shown in the lower part of the display is greater than 60 minutes, the display format changes to show hours, minutes, and seconds. Whenever the time in the center part of the display is greater than 10 hours, the display format changes to show hours, minutes, and seconds.

Basic Data

The term “basic data” refers to the pacer signal setup, and information about your stride length.

Important!

•You cannot change basic data settings while a Stopwatch Mode time measurement operation is in progress. Stopwatch operation must be stopped and the Stopwatch screen must be cleared to all zeros before you can change basic data settings.

•Whenever you want to change the stride length unit, you must first reset the Cumulative Total screen to zero.

•Be sure to update basic data values whenever the person using the watch changes.

Pacer Signal

The pacer signal of this watch beeps in accordance with a pacer value (rate) set by you. You can use the pacer signal to maintain a constant pace while jogging or running. You can also turn off the pacer signal when you do not want to use it.

•The pacer value you set specifies the number of beeps per minute.

•Turning on the pacer signal causes the watch to beep at the rate specified by the pacer value.

•You can set a pacer value in the range of 100 to 200 beats per minute, in units of 5.

•You can disable the pacer function by setting a pacer value of xxx. While the pacer value is set to xxx, the watch does not calculate distance covered.

Stride Length

You can specify either centimeters (XM) or inches (Yn) as the stride length unit. The unit you specify for the stride length unit also determines the unit of measurement used for the distance value in the Stopwatch Mode and Recall Mode, as shown below.

USER’S GUIDE 2575

Stride Length Unit	Setting Range	Setting Increment	Distance Unit
Centimeters (XM)	40 to 190 cm	5 cm	Kilometers (km)
Inches (Yn)	16 to 76 in	2 in	Miles (mi)

•The following examples illustrate how you can calculate values for this setting.

239 steps required to run around a 300-meter track.

300 (meters) ÷ 239 (steps) = 1.255 (approximately 125 cm)

239 steps required to run around a 330-yard track.

330 (yards) ÷ 239 (steps) × 36 = 49.70 (approximately 50 inches)

To configure your basic data

1. While the Stopwatch Mode screen shows all zeros (0 H00'00''00), hold down Buntil the pacer value

appears flashing on the display. This indicates the

setting screen.

2. Press Cto move the flashing in the sequence shown below to select other settings.

			by the Stopwatch Mode.
			• Stopwatch records are stored in “logs” that are created
			automatically by the watch. See “Memory Management”
			for more information.
			• The title screen of the newest log appears first whenever
			you enter the Recall Mode.
			• Log numbers are automatically assigned in sequence,
			starting from 01.
Log number		Creation date	• All of the operations in this section are performed in the

• The cumulative total screen shows the total distance since the last cumulative total distance reset.

• The locations of the lap time and split time (middle or bottom of the display) in the Stopwatch Record screen are determined by the display format you last selected in the Stopwatch Mode.

• The BEST indicator identifies the record that contains the best lap time in the log.

• If a best lap time record is deleted automatically when the log becomes full, the BEST indicator will not be transferred to the record with the next best lap time. See “Memory Management” for more information about automatic deletion of records.

• The unit of measurement used for the distance calculation depends on the unit you select for your stride length as shown in the table below. See “To configure your basic data” for more information.

Selected Stride Unit	Distance Unit
XM (centimeters)	km (kilometers)
Yn (inches)	mi (miles)

To delete a log

1.In the Recall Mode, display the title screen of the log you want to delete.

•See “To reset the cumulative total screen” below for information about what happens when you select the cumulative total screen here.

2.Hold down Aand D until the watch beeps and CLR stops flashing on the display.

•This deletes the log and all the records inside it. Deleting a log does not change the cumulative total distance value.

To reset the cumulative total screen

1.In the Recall Mode, display the cumulative total screen.

2.Hold down A and Duntil the watch beeps and CLR stops flashing on the display.

•This resets the cumulative total distance to zero, without deleting any logs or records. A new cumulative total will start with the next stopwatch operation you perform.
