Setting Up
Place the
POWER SUPPLY UNIT
(Figure
1) on a firm table or other support of
convenient height, with the receptacle
away from the screen. The power sup
ply unit will act as a base for the pro
jector. Unwind the power cord. Set
the projector on the power unit, ap
proximately centered front to rear,
and remove the projector cover.
Be
guided as to the relative location of
the power supply /projector and screen
by the information on page 14.
Rotate the
SUPPLY REEL ARM
up and
forward as far as it will go. Raise the
TAKE-UP REEL ARM
until the
TAKE-UP
BELT
can be put on the take-up pulley.
Do not twist the belts.
When project
ing film on 50-foot or 100-foot reels,
or film on reels with cores smaller
than two inches in diameter, remove
the belt from the supply pulley.
With
these smaller reels, allow the belt to
rest between the pulley and the arm.
The belt should be replaced on the
pulley when the projector is run -in
reverse or when film is being rewound.
Insert the 6-prong
PROJECTOR POW
ER CORD PLUG
into the power supply
unit, and then the 3-prong polarized
power unit plug into a 105- to 125-
volt, 60-cycle, a-c wall receptacle of
the grounding type.
If
you do not
have grounded receptacles, it is sug
gested that for your convenience and
safety, the usual 2-prong receptacles
be replaced with 3-prong polarized re
ceptacles, properly grounded.
If
an
extension cord is to be used, be sure
that it is a 3-wire cord with a
grounded plug, that it has adequate
current-carrying capacity (No. 16
A WG wire or larger) to avoid over
heating the cord, and that it is as
short as possible to prevent excessive
voltage drop.
Position the speaker as close to the
screen as possible. Uncoil enough
SPEAKER CABLE
(Figure 2) to connect
the plug to the
SPEAKER JACK
(Figure
1) in the amplifier. The speaker should
be placed at the ear level of the audi
ence for proper sound distribution.
Move the
FAN SWITCH
and
LAMP
SWITCH
to "ON" (the lamp will not
start unless the fan has been started).
The nature of an arc lamp is such that
it may take several surges of high
voltage direct current from the power
supply unit to start the lamp. This can
be noted as a series of clicking noises.
After the arc is established, less than
45 seconds are required for the lamp
to reach normal operating intensity
and color temperature.
Notice:
The lamp should not be operated
for less ffian three minutes. Operation for
periods shorter than this can reduce lamp
life, diminish light output, and cause un·
even illumination.
Push the
MASTER CONTROL
to the right
as far as it will go. This will turn on
the projector motor, move the douser
out of the way, and allow projection
of the light beam. Rotate the lens back
and forth until the margins of the
lighted area on the screen are sharp.
If
the lighted area needs to be
raised, turn the
ELEVATION CONTROL
clockwise until the area is centered on
the screen.
While the projector is running for
ward,
move the
SPEED SELECTOR
to
SILENT or SOUND, depending upon
the film being projected. To move the
selector from SOUND to SILENT,
push the lever to the left as far as it
will go; to go from SILENT to
SOUND, push the selector upward to
release it-the selector will automati
cally move to the sound position.
Push the master control to the OFF
position.
If
immediate projection is
planned, leave the fan and lamp
turned on.
However, if there will be a
substantial interval of time between
setting up and projection, turn off the
lamp and fan switches ( providing the
lamp has been
on
at
least three min
�). Turn the
VOLUME CONTROL
fully
counterclockwise and the
TONE BAL
ANCE CONTROL
to NORMAL. Momen
tarily depress the
AMPLIFIER POWER
BUTTON
to turn on the amplifier. There
will now be a red glow in the
POWER
ON INDICATOR.
Make sure that the
SOUND-INPUT SWITCH
is set at FILM.
If, with the projector and power
supply properly connected to the pow
er source, the circuit breaker opens,
reset it by pushing down the red but
ton. A serviceman should check the
amplifier if the circuit breaker will
not stay closed.
Note:
Even though the exciter lamp is Ii�
the circuit breaker can be
open.
/
A table lamp or night light plugged
into the
THREAD LIGHT RECEPTACLE
will give sufficient light to thread the
film without the use of room light.
This lamp will be automatically
turned off when the master control
lever is moved to forward PROJECT.
