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".
Note
· In order to obtain accurate calorie and distance calculations, you must set
accurate basic data and keep your exercise pace in accordance with the
pacer signal emitted by the watch.
· Whenever you clear the stopwatch to all zeros, all exercise stopwatch data
(elapsed time, distance, calories burned, recording date) is recorded
automatically in the watch's memory. See "Recall Mode" for more
information.
· 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
input your basic data" for more information.

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.
To set the pacer value
1. While the Exercise Stopwatch Mode screen shows
all zeros (0H00´00´´00), hold down B until the
pacer value appears flashing on the display. This is
the pacer value setting screen.

Data and Setting Scrolling
The A and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during
a scroll operation scrolls through the data at high speed.
Initial Screens
When you enter the Basic Data Input Mode, the data you were viewing when
you last exited the mode appears first.
Timekeeping
· With the 12-hour format, the
P (PM) indicator appears on the display for
times in the range of noon to 11:59 p.m. and the A (AM) indicator appears 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 year can be set in the range of 2000 to 2039.
· The watch's built-in full automatic calendar automatically makes allowances
for different month lengths and leap years. Once you set the date, there
should be no reason to change it except after you have the watch's battery
replaced.
· The current time is displayed in the lower part of the Exercise Stopwatch,
Countdown Timer, Alarm, and Dual Time screens. On these screens, the a.m.
and p.m. indicators are not shown when the watch is configured for the 12-
hour timekeeping format.
Exercise Stopwatch
· 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.
· 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 15 degrees
too high
Animation area
· 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.
