Introduction
This manual explains the installation,
setup, alignment, and maintenance
procedures for the 420A 100 Watt High
Band VHF Transmitter. It is important
that you read all of the instructions,
especially the safety information in this
chapter, before you begin to install or
operate the unit.
Retain Manuals – The manuals for the
transmitter should be retained at the
transmitter site for future reference. We
provide two sets of manuals for this
purpose; one set can be left at the office
while one set can be kept at the site.
Heed Notes, Warnings, and
Cautions – All of the notes, warnings,
and cautions listed in this safety section
and throughout the manual must be
followed.
1.1 Manual Overview
This instruction manual is divided into
four chapters and an appendix. Chapter
1, Introduction, contains information on
safety, maintenance, return procedures,
and warranties. The second chapter
describes the transmitter and includes
discussions on system control and status
and remote control connections. Chapter
3 explains how to unpack, install, setup,
and operate the transmitter. Chapter 4,
Detailed Alignment Procedures, provides
information on adjusting the system
assemblies for optimal operation. The
appendix contains assembly drawings for
the system.
Follow Instructions – All of the
operating and use instructions for the
transmitter should be followed.
Cleaning – Unplug or otherwise
disconnect power from the equipment
before cleaning. Do not use liquid or
aerosol cleaners. Use a damp cloth for
cleaning.
Ventilation – Openings in the cabinets
and tray front panels are provided for
ventilation. To ensure reliable operation,
and to protect the unit from overheating,
these openings must not be blocked.
1.2 Safety
The 100-watt VHF transmitters
manufactured by the Broadcast Systems
Division of ADC Telecommunications are
designed for ease of use and repair while
providing protection from electrical and
mechanical hazards. Listed throughout
the manual are notes, cautions, and
warnings concerning possible safety
hazards that may be encountered while
operating or servicing the transmitter.
Please review these warnings and
familiarize yourself with the operation
and servicing procedures before working
on the transmitter.
Servicing – Do not attempt to service
this product yourself until becoming
familiar with the equipment. If in doubt,
refer all servicing questions to qualified
ADC Telecommunications service
personnel.
Replacement Parts – When
replacement parts are used, be sure that
the parts have the same functional and
performance characteristics as the
original part. Unauthorized substitutions
may result in fire, electric shock, or other
hazards. Please contact the ADC
Telecommunications Technical Service
Department if you have any questions
regarding service or replacement parts.

Chapter 1, Introduction
1.3 Maintenance
returned item be accompanied by a
Material Return Authorization Number
(MRA#).
The 420A is designed with components
that require little or no periodic
maintenance except for the routine
cleaning of the fans and the front panels
of the trays.
An MRA# can be obtained from any ADC
Telecommunications Field Service
Engineer by calling the ADC
Telecommunications Field Service
Department, Broadcast Systems Division,
at (724) 941-1500 or 1-800-215-2614.
This procedure applies to all items sent to
the Field Service Department regardless
of whether the item was originally
manufactured by ADC
Telecommunications.
The amount and time interval between
cleanings depends on the conditions
within the transmitter room. While the
electronics have been designed to
function even if covered with dust, a
heavy buildup of dust, dirt, or insects will
hinder the effectiveness of the cooling of
the components. This could lead to a
thermal shutdown or premature failure of
the affected trays.
Note: To prevent damage to the
product during shipping, ADC
Telecommunications will supply a
shipping container to the customer at
no cost.
When the front panels of the trays
become dust covered, the top covers
should be removed and any accumulated
foreign material removed. A vacuum
cleaner, utilizing a small wand-type
attachment, is an excellent way to
suction out the dirt. Alcohol and other
cleaning agents should not be used
unless you are certain that the solvents
will not damage components or the silkscreened markings on the trays and
boards. Water-based cleaners can be
used, but do not saturate the
components. The fans and heatsinks
should be cleaned of all dust or dirt to
permit the free flow of air for cooling
purposes.
When equipment is sent to the field on
loan, an MRA# is included with the unit.
The MRA# is intended to be used for the
return of the unit to ADC
Telecommunications. In addition, all
shipping material should be retained for
the return of the unit to ADC
Telecommunications. Replacement
assemblies are also sent with an MRA# to
allow for the proper routing of the
exchanged hardware. Failure to close out
these types of MRA#s will normally result
in the customer being invoiced for the
value of the loaner item or the exchange
assembly.
It is recommended that the operating
parameters of the transmitter be
recorded from the meters on the trays
and the system metering control panel at
least once a month. It is suggested that
this data be retained in a rugged folder
or envelope for the life of the equipment.
Photocopies of the log sheet should be
made for continued data entries.
When shipping an item to ADC
Telecommunications, please include the
MRA# on the packing list and on the ADC
Telecommunications-provided shipping
container. The packing slip should also
include contact information and a brief
description of why the unit is being
returned.
1.4 Material Return Procedure
Please forward all MRA items to:
To insure the efficient handling of
equipment or components that are
returned for repair, ADC
Telecommunications requests that each
