Rewinding
To rewind the film, attach its end to the
supply reel and move the reel by hand
a few turns counterclockwise
to bind
the film. (See Figure 5.)
Make sure that the film is not twisted
between the reels.
Lower the rewind tab to its horizontal
position; the tab will block the film
channel.
Move the master control to the MOTOR
(FORWARD & REWIND) position.
Set the speed selector at SOUND; this
is necessary for full-speed
rewinding.
After all the film has been rewound,
latch the rewind tab in the vertical
position and move the master control
to OFF.
After the Show
Following the projection
and rewinding
of all reels of film that were shown:
Turn off the projector.
Unplug the power cord and fold it into
its storage space.
Raise the take-up arm slightly and
remove the belt from the take-up pulley,
guiding the arm to its storage position.
Swing the supply arm downward as far
as it will go.
Lower the projector
by turning the
elevation control counterclockwise
as
far as it will go.
Unplug the speaker cable and wind it
around its storage hooks.
Replace and fasten the projector cover.
Microphone •

Tape Recorder
The projector can be used as a PA
system or to provide accompaniment
for silent films.
Before you use either the microphone
or auxiliary input on the projector,
move
the sound-input
switch to MICRO-AUX
(Figure 6).
Microphone-Insert
the microphone
plug into the
MICROPHONE
RECEPTACLE.
Make sure the plug is in all the way.
The microphone
volume is regulated
by the volume control. Adjust the tone
control to the desired position.
Phonograph or Tape Recorder-Connect
your record player (or tape recorder)
by inserting
its output plug in the
AUXILIARY
INPUT RECEPTACLE.
The plug
must be in all the way. The output
volume is dependent upon the adjust-
ment of the volume control on the
projector.
A comfortable
operating
level for this input is 500 mV.
NOTE: The auxiliary input circuit
of the projector
is high impedance
to match crystal orceramic
phono-
graphic pickups; it will also accept
the output of a preamplifier,
which
must be used if the phonograph
pickup is of the magnetic type.
The microphone
input is designed
for use with a low-impedance
dynamic microphone.
