8 Set the speed switch Ba to"24" or" 1 8' depending upon whether the film you are going to show
is intended to be projected at 24 or 18 fps (frames per second). Almost all professionally made
sound films need the 24 fps position. Old silent films and some films with magnetic sound tracks
need 18 fps. If the action on the screen is unnaturally fast or slow, or if speech is excessively deep
or high pitched, the wrong speed has been chosen. The speed can be changed without stopping
the projector.
9 Check that the air intake on the non-operating side of the projector is not obstructed. The
projector is now ready to be threaded.
Automatic threading
10 Raise the front spool arm until, with a click; it locks in the running position.
11 Raise the rear spool arm until it locks with a click at the horizontal position.
12 Place the spool carrying your film on the front spool spindle (if necessary lifting the Spool lock
12a until it is in line with the spindle) in such a way that the film hangs down from the front of the
spool. Check that the sprocket holes are on the side of the film furthest from the projector. If they
are on the projector side when the film is hanging down from the front of the spool, rewinding is
required (as described in Stage 24). Secure the spool by pressing the spool lock until it clicks into
position at right angles to the spindle.
13 Attach to the rear spindle an empty spool of sufficient capacity for the film you are going to
show, and secure it with the lock. The projector will accept spools of up to 2,000ft (61 Om)
capacity. The spool supplied carries 1 ,600ft (490m) of film.
14 If necessary, set the run/still/ever to the forward position.
15 Place the tip of the film in the cutter numbered and, after ensuring that the two small studs 1
5a have entered two of the perforations, press the cutter handle firmly towards the projector
until, with a click, it trims the film. Make sure before operating the cutter that enough film is
trimmed away for all damage in the region of the tip to be removed.
16 Press the automatic threading lever '2" downwards and to the right so that it locks in the
threading position (16a). Rotate the function switch 16b to the arrowed position labelled "3" to
start the projector mechanism.
17 Holding the film horizontally slide the tip into the slot below the blue roller "4". When you feel
the film being drawn in by the projector mechanism, release it.
18 Watch the exit rollers at the rear of the projector and take hold of the film as soon as it
emerges. When about 20in (50cm) of film has passed the exit rollers, turn the function Switch
back to the vertical "off" position. Pull gently on the film until, with a click, the threading lever
returns to its original (running) position 1 Ba,
