Thyristor
Circuit
Your Vivit
ar
Model 283 has a unique power conseNalion
system called a thyristor circUit.
Th
is circuit saves the excess
energy nol needed for a proper exposure thereby providing
incredibly fast recycling and a greater number of flashes
per charge. The recycle time and tho number of flashes per
charge varies
depend
i
ng
on
!he
fl
ash-to-subject dislance.
As
you move the flash closer to the subject, the 283 recycles
fa
ster, and is capable of providing more lIashes per set
of batleries.
Th
e
Sulliclent
Lighllndicator
Th
e Sufficient Light Indicator @ on your Vivitar 283 lets
you know before you take a picture if the light output will be
su
fficient for a good exposure. It may be used when shooting
in any of the four automatiC modes, and is
es
pecially helplul
in bounce light situations normally ICquiring complex
exposure calculallons.
To

Sufficient Light Indicator:

I-stops,
re
ler to the
"Au

of the Specilications for the best I-stop to use. The numbers
wi/hin each triangle indicate

1
Plug the Sensor @ into the flash
