Backlight

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.
• You can specify 1.5 seconds or 2.5 seconds as
the illumination duration.
• See “Backlight Precautions” for other important
information about using the backlight.

To turn on the backlight manually
Press L in any mode to illuminate the display.
• The above operation turns on the backlight regardless of the current auto
light switch setting.
• The backlight is disabled while you are performing a bearing sensor
calibration operation in the Digital Compass Mode.
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on, 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.
• Wear the watch on the outside of your wrist.
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.
