Viewing the Face in the Dark

The watch has a light that illuminates the face
for viewing in the dark.

To illuminate the face manually

●
Press (B) to turn on illumination.
Illumination will turn off automatically if an
●
alarm starts to sound.
Using Auto Light
●
If Auto Light is enabled, face illumination will
turn on automatically whenever the watch is
positioned at an angle of 40 degrees or more.
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.
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.
