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.
To illuminate the face when Auto Light
●
is enabled
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.
Frequent use of illumination will run
●
down the battery.
