BACKLIGHT

The backlight uses an EL (electro-
Auto light switch on indicator
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.
• Be sure to wear the watch on the outside of your left wrist while using the
auto light switch.
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.

Warning!
• Always make sure you are in a safe place whenever you are reading
the display of the watch using the auto light switch. Be especially
careful when running or engaged in any other activity that can result
in accident or injury. Also take care that sudden illumination by the
auto light switch does not surprise or distract others around you.
• 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. Sudden and unintended operation of the
auto light switch can create a distraction, which can result in a traffic
accident and serious personal injury.
