Illumination
An EL (electroluminescent) panel is used to illuminate the display for easy reading in the
dark. An auto light turns on illumination automatically when you angle the watch towards
your face for viewing.

To turn on illumination manually
In any mode, press the
This will turn on illumination for about 1.5 seconds.
• Pressing the L button turns on illumination regardless of
whether the auto light switch is on or off.
❚
To turn the auto light switch on or off
The auto light switch turns on illumination for about 1.5 seconds when you angle the watch
towards your face.
In the Timekeeping Mode, hold down the

Turning on Illumination with Auto Light
With the watch on your
wrist, position it parallel
with the ground.
• You should be wearing the watch on the outside of your
wrist when using auto light.
• Make sure that a line running from the left side (9 o’clock) to
the right side (3 o’clock) of the watch is within ±15 degrees
parallel with the ground. Auto light may not operate properly
if the angle is greater than 15 degrees.
Important!
• Illumination may be difficult to see under bright sunlight.
• Illumination turns off automatically if an alarm sounds, etc.
• You may notice a slight sound from the watch while illumination is turned on. This is the
sound of EL panel vibration and does not indicate malfunction.
Rotate your arm so the watch
is angled at about 40 degrees,
so you can read its face.

Auto Light Precautions
• To conserve battery power, the auto light switch can remain on for a maximum of about six
hours. After that, it will turn off automatically, and the “ ” indicator will disappear from the
display.
• If you want to continue using auto light, hold down the D button for about two seconds
again until the “ ” indicator reappears. Note, however, that frequent use of auto light
can run down the battery.
• Illumination may not turn on immediately when you angle the watch towards your face. This
does not indicate malfunction.
• Illumination remains turned on for about 1.5 seconds only, even if you leave the watch
angled towards your face.
• Illumination may turn on unintentionally when you wear the watch on the inside of your wrist,
when you shake your arm, or when you raise your arm. Be sure to turn off the auto light
switch whenever you do not need illumination.
• Keep the auto light switch turned off whenever you are wearing the watch on the inside of
your wrist.
• Electro-static charge and magnetism can interfere with auto light operation and even make
operation impossible. If this happens, lower your arm to the starting position and then raise it
again. If you still have trouble with auto light illumination, try lowering your arm down to your
side and then raise it to your face for reading.
• You may hear a faint rattling sound when you move the watch around. This sound is caused
by the movement of a metal bulb that controls operation of the auto light switch, and does
not indicate malfunction.

Operation Guide 2984
Using the Stopwatch
Whenever you perform a lap/split time operation, the stopwatch stores a record of the lap/
split time. There is enough memory to hold up to 60 lap/split time records. For each
measurement operation, the watch also creates and store a title screen (which also takes
up one record in memory) that shows the distance and the date of the measurement.
The watch calculates the distance covered using elapsed time, based on a fixed pace.
• In the Timekeeping Mode, press the C button once to enter the Stopwatch Mode.
• For the stopwatch to be able to perform distance calculations, you need to use the
procedure under “Configuring Individual Preferences” to specify your stride length and other
information.

Memory
The watch’s memory can be divided into multiple measurement logs. Each log has its own
title screen that shows the distance and date of the measurement, which takes up one
memory record. The memory’s maximum capacity is 60 lap/split time records, plus at least
one log title screen, for a total of 61 records.
• When memory becomes full, the watch automatically deletes old data to make room for
newly measured data.
Example 1: Memory usage when the current elapsed time measurement is the only
Example 2: Memory usage when there are multiple elapsed time measurements in
• For information about recalling stopwatch records, see “Viewing Stopwatch Records”.
Data Save Timing
Whenever you press the D button to display a lap/split, the lap/split time and distance are
stored in memory. Stopping the elapsed time operation and pressing the D button to reset
the stopwatch to all zeros stores the final distance in memory.
Memory Full
Storing data when memory is full automatically deletes the oldest record currently in
memory to make room for the new data.

Lap Times and Split Times
A lap time is the time that elapses during a specific portion of the race, such as a lap around
a track, while a split time is the time that elapses from the beginning of a race up to a
certain point.

Determining Your Stride Length
You can determine your stride length as shown below by running a known distance and
then dividing by the number of steps it took.
• The stride length setting can be configured in 5cm units, so round your calculation result off
to the nearest 5cm.
Example 1: When you take 25 steps to run the length of a tennis court (23.77 meters)
Example 2: When you take 239 steps to run one lap around a 300-meter track
23.77 (meters) ÷ 25 (steps)= 0.9508 (meters)
