Light

The watch has an LED light that you can use
to illuminate the display for about two seconds
for viewing in the dark. When turned on,
illumination becomes gradually brighter and
then gradually dimmer.
The watch also has an auto light function that
automatically illuminates the display
whenever the watch is angled for reading in
the dark.
Illuminating the Display
Manually
Pressing (B) turns on illumination.
The LED light will turn off automatically if the
●
alarm starts to sound.

Auto Light

If Auto Light is enabled, display illumination
will turn on automatically whenever the watch
is positioned at an angle of 40 degrees or more
when it is dark.
Important!
Auto Light may not operate properly
●
when the watch is at a horizontal
angle of 15 degrees or greater from
horizontal as shown in the illustration
below.
Auto Light may operate
●
unintentionally and run down the
battery if the watch is blocked from
light by your sleeve.
Electro-static charge or magnetism
●
can interfere with proper auto light
operation. If this happens, try
lowering your arm and then angle it
towards your face again.
When moving the watch you may
●
note a slight rattling sound. This is
due to operation of the auto light
switch, which determines the current
orientation of the watch. It does not
indicate malfunction.
Note
Auto Light is disabled when any one
●
of the conditions below exists.
