P a n chromatic TQIII & TQIII Specialist User Manual
Page 2
Foreword
This is a long instruction manual but that is not because your projector is difficult to use. The
operating procedure, as you will discover, is simple. The reason the manual is a long one is that
the projector will have a long working life. From time to time, lamps will fail and sooner or later
you may encounter films which are in too poor a condition to be projected without special
techniques. We want you to know what to do when these things happen so that your
presentations are never spoiled.
As you will probably be eager to show a film as quickly as possible, we offer a "reading plan".
Stages 1 t 31 should be studied before you set up the projector for the first time, or while you are
doing it. Stage 32— concerned with difficulties - can be left until difficulties arise (although you
will be a better projectionist if you read this section before your first presentation so that you
know what to do if anything goes wrong).
Stages 33-50 have been included because there are certain teaching applications in which users
may wish to thread or unthread the projector manually. If, like the majority of users, you always
leave the projector to thread itself automatically, this section need not be read. Finally, there are
Stages 51 -69 on routine maintenance. These are important but can be ignored until you have
projected a few spools of film and become familiar with the controls.
Instructions for making recordings on Model 1694 begin at Stage 71.
WARNING THIS APPLIANCE MUST BE EARTHED

Each numbered illustration in this manual relates to the stage with the same number. In the text, a combination of a
number & a letter refers to a detail in the similarly numbered (and usually adjoining) illustration. For example, 3d is
the voltage selector pointer d in the illustration to Stage 3. Numbers in quotation marks, e.g. “3” refer to a similarly
numbered part of the projector itself. Instructions which apply to some but not all models in the TQ and TQ Specialist
ranges are printed in
italic type. References to the run/still lever apply only to the Specialist models only.
