lnstalling
the batteries
Release the battery holders
by
pressing
the
grip
clips on
each side of
the battery
pack,
and
pull
them out.
Place
four
penlight
batteries in each
holder
MS-2, making sure
that the
positive
and negative
(+
and
-)
terminals
are
lined up correctly. Then fit
the battery-loaded
holders
back
into the
MB-2 until they click into
position.
Life-span
of
the batteries
The number of
rolls of film that can be shot
with one set
of batteries is difficult
to
predict
accurately, since
this
depends
on too many
variable factors. In
the
same
man-
ner, the
number of rolls
of film
that can be
shot at the
motor drive's rated speed
varies with the types of bat-
teries
used. The rated
firing speed can be maintained
for
approximately
ten 36-exposure rolls of
film when
zinc-
carbon batteries are
used, and
for
about 20
rolls
of
film
when alkaline-manganese batteries are
used. These
amounts can be extended
to approximately 50 and
80
rolls, respectively, but
with a corresponding slowdown
in
the firing speed.
