Motor runs advancing the film forward.
Projection lamp is turned on for forward projection.
Push the SET/STOP Red Switch, and the motor stops, the lamp is turned off, and
the film path is now fully open.
Green LED is illuminated, which is the starting position.

"REWIND Switch.
Rewinds the film through the mm path.
Conventional rewinding from reel to reel can also be done.
To stop rewinding, push either"
11+ "
Rewind Switch, or "SET /STOP" Switch.
Rewind will stop and for approximately 6 seconds Red LED of Rewind Switch
blinks indicating that during the blinking period no new operation command is
possible.
Note : The touch button control system employs logic "ON/OFF", that is, the first
push of the switch is a command "ON" and the second push of the same switch
is a command "OFF".
Also, at any mode of operation,pushing the "SET/STOP" Switch stops the projector
and revert to the starting position with the film path fully open.

The Slim Line series projectors are available for voltage from 1 OOV, 11 OV, 120V,
220V and 240V. 110/220V and
l
20/240V dual voltage models are also available.
According to the electrical safety regulations of various countries, UL (USA), CSA
(Canada), VOE (Germany),SEV (Switzerland), SAA (Australia), SEMKO (Sweden),
NEMKO (Norway), FEMKO (Finland), DEMKO (Denmark), specific models are
manufactured to meet such regulations, including the option of 50/60Hz sound only.
50Hz sound

silent operation.
Power Transformers vary according to the voltage range and also to the electrical
safety requirements of each country. The secondary windings of all transformers
provide 8V AC to the pilot lamp and exciter lamp circuits, 46V AC to the amplifier,
24V AC (high) and 22V AC (low) to the halogen projection lamp.
Motor ON/OFF, Lamp ON/OFF and Rewinding can be controlled by the function
switch which consists of a cam bracket and 4 micro switches. The function switch
cam also mutes the audio during rewind and the "STOP" or threading position.
The projection lamp is a HALOGEN ELC type 24V 250W. Inside of the lamp house
is a "high-low" switch to help extend the lamp life. In the "high" position average
lamp life is approximately 50 hours and at the "low" position about 150 hours.
Note The HALOGEN LAMP EJ L type 24V 200W may also be used with some reduction in
light output.
Models SSL-OL use the 300W 120V EWG or EYK lamp.
The motor is an induction type with capacitor. Motors are available for all the voltage
ranges. Transformers and motors are simple and easy-to-replace modules.
AC power cords, line terminals, and all other electrical parts are designed to meet
the safety requirements of the individual countries listed.
