USER’S GUIDE 2535

If the display of the watch is blank...

If the SLEEP indicator is on the display, it means that the

display is blank because the watch’s Power Saving

function has turned off the display to conserve power.

Power Saving automatically turns off the display and puts

the watch into a sleep state whenever your watch is left

for a certain period where it is dark.

• The initial factory default setting is Power Saving on.

• The watch recovers from the sleep state if you move it to

a well-lit area

, if you press any button, or if you angle

the watch towards your face for reading.

It can take up to five seconds for the display to turn on.

• See “Power Saving Function” for more information.

About This Manual

Stopwatch

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.

• See “How Stopwatch Data is Stored” for information about the type of data the watch

stores in memory when you use the stopwatch.

• 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.

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.

• 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.
