1/100 second
The exercise stopwatch is a 1/100-second stopwatch that
measures elapsed time, split time, and two finishes. The
exercise stopwatch uses the data you input in the Basic
Data Input Mode and a pacer signal to calculate the
number of calories you burn and the distance you cover
while jogging or running.
• The stopwatch measurement operation continues even
if you exit the Exercise Stopwatch Mode.
• Exiting the Exercise Stopwatch Mode while a split time
is frozen on the display clears the split time and returns
to elapsed time measurement.
• Stopwatch measurements are performed in the Exercise
Stopwatch Mode, which you enter by pressing C.
Timekeeping Mode time
How the Exercise Stopwatch Works
There are two ways you can use the exercise stopwatch: to measure elapsed time like
a standard stopwatch (see “To measure times with the stopwatch”), and to keep track
of the number of calories you burn or the distance you cover while jogging or running.
In order to use the exercise stopwatch to keep track of calories and distance, you
must first perform the steps listed below.
1. Set your basic data. See “Inputting Basic Data”.
2. Configure the pacer signal. See “About the Pacer Signal”.

• If you have red or blue selected for the current time in the Timekeeping Mode,
pressing A during an elapsed time operation causes the split time to appear on the
display in red.
• If you have red or blue selected for the current time in the Timekeeping Mode, the
elapsed time changes to blue after you reach your target calorie value.
• The current calories count is updated at 30-second intervals.
About the 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 disable the pacer function by setting a pacer value of xxx. While the
pacer value is set to xxx, the watch does not calculate calories burned and
distance covered, so both values are indicated as zero on the display.

Backlight
Auto light switch on
indicator
The backlight uses an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The watch’s auto light switch automatically turns on
the backlight when you angle the watch towards your
face.
• The auto light switch must be turned on (indicated by
the auto light switch on indicator) for it to operate.
• See “Backlight Precautions” for other important
information about using the backlight.
To turn on the backlight manually
In any mode, press L to illuminate the display for about
one second.
• The above operation turns on the backlight regardless
of the current auto light switch setting.
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about one second,
whenever you position your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes the backlight to turn on.
Parallel to ground
• An animated figure appears in the animation area while
a stopwatch operation is in progress, even if you change
to another mode.
• The values for the number of calories burned produced
by this watch include both calories normally burned
through normal metabolism and rest and extra calories
burned by jogging or running.
• This watch is set up to calculate calories burned by men
while jogging. Women should decrease the values
produced by this watch by 5%.
Backlight Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• The backlight automatically turns off whenever an alarm sounds.
• Frequent use of the backlight shortens the battery life.
Auto light switch precautions
• In order to protect against running down the battery, the auto light switch
automatically turns off approximately five hours after you turn it on.
• Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
More than 15 degrees
too high
• The backlight may not light if the face of the watch is
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
• The backlight turns off in about one second, even if you
keep the watch pointed towards your face.
More than 40 °
• Static electricity or magnetic force can interfere with proper operation of the auto
light switch. If the backlight does not light, try moving the watch back to the starting
position (parallel with the ground) and then tilt it back toward you again. If this does
not work, drop your arm all the way down so it hangs at your side, and then bring it
back up again.
• Under certain conditions, the backlight may not light until about one second after
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
