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
• 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.
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.

To measure times with the stopwatch
Note
• Pressing D to 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 B to
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.
Lap/Split number

time
• 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.

• 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.
