BACKLIGHT
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.
Turning on the Backlight manually
In any mode (except for the World Time Mode), press B to illuminate the
display for about two seconds.
• 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 two
seconds, whenever you position your wrist as described below in any mode.
• See “Backlight Precautions” for other important information about using
the backlight.
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 light.

Warning!
• Never try to read your watch when mountain climbing or hiking in
areas that are 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 vehicle. 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

In the Timekeeping Mode, hold down B for two seconds to turn the auto
light switch on (Auto light switch on indicator displayed) and off (Auto light
switch on indicator not displayed).

want.
