as wefl as with the following accessories which wil1- be fouad inside
the lld of the case :
- one oilcan - one screwdriver - one brush - two spare fuses,
The 3-221 nro'ieetor is fitted with a standarddocus lens of focal
length 5O mn. Two other focal length lenses afe availabJ-e :
- e 35 mm
lensr inteno.ed.
for short projection distancesl
- a 70 mmlens, intended for long projection distances.
PAIIIARD-BOLEX lenses are specially designed to produce pictures
of maximumbrilliance, sharpness and contrast.
The microphone, type D l1-Hi (Coae : SOMIC), which can be supplied on
request with lJ ft of cable, may al.so be stowed away inside the lid.
Use of the special earrying bag (Code : S0H0U), supplied. on request,
is strongly recommended, as this bag effectively protects the lined pro-

HOW

- Arransement of Projector and Screen
The distance from the screen depends
on the size of the screen and on the
focal length of the lens used. The
diagram opposite shows the size of the
picture produced on the screen when
using projection lenses of focal length
35, 50 and 70 mm
at various projection
dlstances.

A room lamp can be plugged into the r.mi-
versal-type socket of the projector.
This lamp is switched off automatically
when the projection lamp is switched on
and vice versa. The room lamp outlet has
a socket for both E'aropean
and American
t;rpe plugs. Use a bul-b of I10 to l}0
volts, which is the voltage available
with the .:niversal-type socket. If the
bulb is destined for a higher vol_tage,
