Automatic Operation
Th
e Sensor
Your Vivita r 283 Electronic Flash
is
equipped with a
Re
moftable Sensor ® that measures
the
light reflected from
the
sueject and other reflective surfaces near the subject.
This
inlormallOn is interpreted
by
a solid stale computer
in
the Sensor which programs the Ilash
to
provide just the right
amount of light required for a perfect exposure. The practical
advantage is that you
don't
have
to
change lhe I-stop
on
your camera lens
wh
en you move closer to a subject
or
larther away, As long as your subject is within the automatic
operating range of the flash
lor
that I-stop, the computer
au
tomatically makes the adjustment for you.
To remove the
Sensor from the
p'.lll it straight out from the body
flash .
To
mount the Sensor back
on
the flash, align the
black
ridge at the
back of the
Sensor with the groove in
the
Sensor Sock
et
CD
and push the Senso
rl
irmly into the flash.

means for controlling the depth
