alarm to become activated.

to light.
• The brightness alarm sounds only once and then turns off automatically.
Note

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.
• 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.
