Backlight

The backlight uses an EL (electro-luminescent) panel that

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. Note that this

watch features a "Full Auto EL Light," so the auto light switch operates only when

available light is below a certain level. It does not turn on the backlight under bright

light.

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.
