GENERAL SERVICE INFORMATION
SAFETY NOTICE
Ikt,RNI NG
VOLTAGES USED FOR THE OP-
TILIS EQUIPMENT
ARE DANGEROUS TO HUMAN
LIFE.
This instruction manual is written for the
general guidance of maintenance and service
personnel Who are familiar with ane. aware
of the dangers of handling electric and elec-
tronic circuits. It does not purport to in-
clude a complete statement of the safety
precautions which should be observed in
servicing this or other electronic equipment.
The servicing of this equipment by inade-
quately trained or inexperienced personnel
involves risks to such personnel and to the
equipment for which the manufacturer can
not accept responsibility. Personnel ser-
vicing this equipment should familiarize
themselves with first -aid treatment for elec-
trical burns and electrical shock.
PRODUCTION CHANGES
From time to time it becomes necessary
to make changes in the equipment described
in this book. Such changes are made to im-
prove performance or meet component short-
ages and are identified by a revision letter
following the model number stamped on the
nameplate. The changes in the equipment as
they affect the instruction book are listed on
a Production Change Sheet included in the
book. If no Production Change Sheet is in-
cluded, no changes have been made. The
revision letter appearing on the title page
indicates the equipment revision to which
the book corresponds.
This inforrna;loil is provided as servIc-
ing aid; it should not be used to modify
earlier equipments to incorporate later re-
visions except under specific instructions.
Please mentio.n the revision letter in any
correspondence.
REPLACEMENT PARTS
The parts list contained in this book in-
cludes all principal replacement parts. The
symbol numbers are the same as those ap-
pearing on e7ernentary and other drawings.
Wnenever possible, replac parts should
be obtained from a local electronics supply
dealer. If it is necessary to order a part
(other than a tube or transistor) from the
General Electric Company, please include
the symbol number, description, and draw-
ing number of the part and model number of
the unit. Orders may be sent to the nearest
office appearing on the list at the end of the
book or the General Electric Company,
Visual Communication Products, Electronics
Park, Syracuse, N.Y.
REPLACEMENT TUBES AND
TRANSISTORS
In all cases replacements must be or-
dered from a local distributor.
These instructions do not purport to cover all details or variations in equipment nor to provide for every
possible contingency to be met in connection with installation, operation, or maintenance. Should further
information be desired or should particular problems arise which are not covered sufficiently for the pur-
chaser's purposes, the matter should be referred to the General Electric Company.

WARRANTY
The General Electric Company (herein-
after called the Company) warrants to the
Purchaser that the equipment will be free
from defects in material, workmanship, and
title, and will be of the kind and quality
designated or described in the contract. The
foregoing warranty is exclusive of all other
warranties whether written, oral, or implied
(including any warranty of merchantability
or fitness for purpose. If it appears within
one year from the date of shipment by the
Company that the equipment described in
this instruction book does not meet the war-
ranties specified above and the Purchaser
notifies the Company promptly, the Company
shall thereupon correct any defect, including
non-conformance with the specifications, at
its option, either by repairing any defective
part or parts or by making available at the
Company's plant, a repaired or replacement
part. In lieu of the foregoing, the standard
published tube warranties in effect on the
date hereof shall apply to new electronic
tubes. If the equipment is installed, or its
installation supervised, by the Company
said one year shall run from the completion
of installation provided same is not unreason-
ably delayed the Purchaser. The conditions
of any test shall be mutually agreed upon
and the Company shall be notified of and
may be represented at all tests that may be
made. The liability of the Company to the
Purchaser (except as to title) arising out of
the supplying of the said equipment, or its
use, whether on warranty, contract or neg-
ligence, shall not in any case exceed the
cost of correcting defects in the equipment
as herein provided and upon the expiration
of said one year, all such liability shall
terminate. The foregoing warranty does not
apply to any used equipment supplied under
contract or any equipment supplied under
contract which bears a trademark of a
manufacturer other than that of the Company.
Because of the more restrictive warranties
expressed by other manufacturers, the Com-
pany under contract can only make avail-
able to the Purchaser the warranty of the
manufacturer on all such equipment. The
Company will secure for the Purchaser at
manufacturer's
standard published warranty applicable to
all such equipment. Used equipment is sold
as is without warranty unless otherwise
specifically provided in writing in the sales
contract. The foregoing shall constitute the
sole remedy of the Purchaser and the sole
liability of the Company.

INTRODUCTION
The General Electric Color Camera, Model
4PC19D3, is designed to provide alive pickup
color television signal through the use of sep-
arate mesh Plumbicon tubes and a sophisti-
cated optical system. The Color Camera con-
tains an Angenieux Zoom lens designed by
the Television Zoomar Company. The lens
system provides a faster Color Camera,
The following items are supplied.
E BI -6351
color separation, and mechanical simplicity,
in addition to the flexibility of a 10:1 zoom
lens with custom engineered controls. The
maneuverability and balance of the Color
Camera, after mounting, along with precise
micromanipulation of its range and focus
control, give it a versatility for both indoor
and outdoor television coverage.
