Illumination

The display of the watch is illuminated by an LED (light-
emitting diode) and a light guide panel for easy reading in
the dark. The watch’s auto light switch turns on
illumination automatically when you angle the watch
towards your face for reading.

The auto light switch must be turned on (indicated by
the auto light switch indicator) for it to operate.

See “Illumination Precautions” for more important
information.

To illuminate the display manually

In any mode, press 

L

 to turn on illumination for about

one second.

The above operation turns on illumination regardless of
the current auto light switch setting.

About the Auto Light Switch

While the auto light switch is enabled, illumination turns on whenever you position
your wrist as described below in any mode.

Moving the watch to a position that is parallel to the ground and then tilting it
towards you at more than 40 degrees causes illumination to turn on.

 •

 Wear the watch on the outside of your wrist.

Warning!

Always make sure you are in a safe place whenever you are reading 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 startle 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.
