Nikon MD-12 - Battery Performance; Specifications

TROUBLESHOOTING
rf
Your MD-l2 has
been designed to
make
motor drive
photography
as
simple and
trouble-free as
possible.
However,
should
you
operate the
camera
incorrectly
or
without clearly understanding
what
you
are
doing,
minor
"hitches"
may
occur.lf
this
occurs,
please
follow
the
instructions
below.
lf the motor
drive
"jams" during operation,
this usually
means
that
the controls
have either
been
operated
incorrectly
or in the wrong
sequence,
and the coupling
mechanism
has
disengaged.
Should this
occur,
turn
the MD-12's
power
switch
off
and
make
one exposure
with the
camera's
shutter
release
button,
remembering,
in
the case
of the
FM
(Serial
No.
below 3,000,000),
to
switch over
to
manual film advance.
You
may
find that
the motor drive did
not
finish advancing
the film.
lf so, complete the film advance using
the camera's
film advance lever, then
press
the
shutter
release but-
ton. Do not advance the film.
Switch
the motor drive
back
on and,
in
the
case of
the FM
(Serial
No.
below
3,000,000), revert to the motor drive mode. The motor
drive
should advance the film ready
for the next ex-
posure.
lf
this
does not
clear the
malfunction
or
you
are
unable
to
move
the
film advance lever at
all.
do
not try to
force
the controls.
Turn the
motor drive
off once
more and
simply remove the
motor
drive
from
the
camera.
This will clear the tension
in
the film
advance
mechanism,
allowing
you
to advance
or
finish
advancing
the
film
and make
one exposure,
again do
not advance
the film.
Reattach the motor
drive
and,
in the case of the FM
(Serial
No. below
3,000,000),
switch
to
motor drive operation. When
ybu
switch the
motor drive
back on, the
film should then
advance
one
frame
ready
for
ihe next exposure.
Should
you
trigger
the
motor drive
with the
shutter
speed
dial set to
"8"
the
absence
of an
"exposure
com-
plete
signal"
may result
in the camera's
mirror
locking
up
and the
shutter remaining
open.
To restore
normal
operation
in the event
of
this happening,
merely
move
the
shutter
speed dial away from "8."
At all
times
during
motor drive
operation,
the film
advance
lever
should remain flush
with
the back
of
the camera.
lf
you
move
it out to its
stand-off
position,
the
motor
drive will
stop. Returning
the lever
to its
flush
position
will automatically
start the
motor
drive
once more.
