Note
• The backlight of the watch employs an electro-luminescent
FLASH indicator
(EL) light, which loses illuminating power after very long
use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The watch will emit an audible sound whenever the display is illuminated. This is caused
by a transistor that vibrates when the EL panel lights up. It does not indicate malfunction
of the watch.
• The backlight automatically turns off whenever an alarm sounds.
To manually turn on the backlight
Pressing L in the Timekeeping, Stopwatch or Alarm Mode causes the backlight to turn
on for about two seconds. Pressing C in the Beat Counter Mode also causes the backlight
to turn on for a fixed amount of time.
• The backlight normally stays on for about two seconds and then turns off automatically.
When the EL alarm is turned on, however, the backlight stays on for about five seconds
instead of two seconds.
• The above operations turn on the backlight, regardless of the current auto light switch
and EL alarm settings.

About the Auto Light Switch
While the auto light switch is turned on, the backlight automatically lights for about two
seconds whenever you position your wrist as described below. 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.
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 illuminate.

• The backlight may not illuminate if the face of the watch is more than 15 degrees off
the parallel as shown below. Make sure that the back of your hand is parallel to the
ground.
Parallel to ground
• Static electricity or magnetic force can interfere with proper operation of the auto light
switch. If the auto light switch does not illuminate, 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 or less
after turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.

dark or in areas with poor footing. Doing so is dangerous and can result in
serious personal injury.
• Never try to read your watch when running where there is danger of accidents,
especially in locations where there might be vehicular or pedestrian traffic. Doing
so is dangerous and can result in serious personal injury.
• Never try to read your watch when riding on a bicycle or when operating a
motorcycle or any other motor cycle. Doing so is dangerous and can result in a
traffic accident and serious personal injury.
• When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor vehicle.
