Analog UHF Driver/Translator Chapter 1, Introduction
LX Series, Rev. 0 1-1
Chapter 1
Introduction
This manual explains the installation,
setup, alignment, and maintenance
procedures for the Innovator LX Series
modular UHF translator. 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.
1.1 Manual Overview
This instruction manual is divided into
five chapters and supporting appendices.
Chapter 1, Introduction, contains
information on the assembly numbering
system used in the manual, safety,
maintenance, return procedures, and
warranties. The second chapter describes
the translator and includes discussions on
system control and status indicators and
remote control connections. Chapter 3
explains how to unpack, install, setup,
and operate the translator. Chapter 4
contains circuit-level descriptions for
boards and board-level components in
the translator. Chapter 5, Detailed
Alignment Procedures, provides
information on adjusting the system
assemblies for optimal operation. The
appendices contain a sample log sheet,
test data sheet, assembly and
subassembly drawings and parts lists,
and system specifications.
1.2 Assembly Designators
Axcera has assigned assembly numbers,
such as Ax (x=1,2,3…), to all assemblies,
trays, and boards that are referenced in
the text of this manual and shown on the
block diagrams and interconnect
drawings provided in the appendices.
These supporting documents are
arranged in increasing numerical order in
the appendices. Section titles in the text
for assembly or tray descriptions or
alignment procedures contain the
associated part number(s) and the
relevant appendix that contains the
drawings for that item.
1.3 Safety
The UHF translators manufactured by
Axcera are designed to be easy to 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 translator. Please review these
warnings and familiarize yourself with the
operation and servicing procedures
before working on the translator.
Read All Instructions –All of the
operating and safety instructions should
be read and understood before operating
this equipment.
Retain Manuals –The manuals for the
translator should be retained at the
translator 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 all Notes, Warnings, and
Cautions –All of the notes, warnings,
and cautions listed in this safety section
and throughout the manual must be
followed.
Follow Instructions –All of the
operating and use instructions for the
translator should be followed.
Cleaning –Unplug or otherwise
disconnect all 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 the reliable

Analog UHF Driver/Translator Chapter 1, Introduction
LX Series, Rev. 0 1-2
operation of the translator, and to protect
the unit from overheating, these
openings must not be blocked.
Servicing –Do not attempt to service
this product yourself until becoming
familiar with the equipment. If in doubt,
refer all servicing questions to qualified
Axcera 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 Axcera
Technical Service Department if you have
any questions regarding service or
replacement parts.
1.4 Maintenance
The Innovator LX Series Translator 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.
The amount of time 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 affect the
cooling of the components. This could
lead to a thermal shutdown or the
premature failure of the affected trays.
When the front panels of the trays
become dust covered, the top covers
should be taken off and any accumulated
foreign material should be 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 silk-
screened 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.
It is recommended that the operating
parameters of the translator 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. A sample format for a log
sheet is provided in Appendix A.
Photocopies of the log sheet should be
made to allow for continued data entries.
1.5 Material Return Procedure
To insure the efficient handling of
equipment or components that have been
returned for repair, Axcera requests that
each returned item be accompanied by a
Material Return Authorization Number
(MRA#).
An MRA# can be obtained from any
Axcera Field Service Engineer by
contacting the Axcera Field Service
Department at [phone] or by fax
at [phone]. This procedure
applies to all items sent to the Field
Service Department regardless of
whether the item was originally
manufactured by Axcera.
When equipment is sent to the field on
loan, an MRA# is included with the unit.
The MRA# is intended to be used when
the unit is returned to Axcera. In
addition, all shipping material should be
retained for the return of the unit to
Axcera.
Replacement assemblies are also sent
with an MRA# to allow for the proper
routing of the exchanged hardware.
Failure to close out this type of MRA# will
normally result in the customer being
invoiced for the value of the loaner item
or the exchange assembly.
When shipping an item to Axcera, please
include the MRA# on the packing list and
on the shipping container.

Analog UHF Driver/Translator Chapter 1, Introduction
LX Series, Rev. 0 1-3
The packing slip should also include
contact information and a brief
description of why the unit is being
returned.
Please forward all MRA items to:
AXCERA, LLC
103 Freedom Drive
P.O. Box 525
Lawrence, PA 15055-0525 USA

EMERGENCY FIRST AID INSTRUCTIONS
Personnel engaged in the installation, operation, or maintenance of this equipment are urged to become
familiar with the following rules both in theory and practice. It is the duty of all operating personnel to be
prepared to give adequate Emergency First Aid and thereby prevent avoidable loss of life.
RESCUE BREATHING
1. Find out if the person is
breathing.
You must find out if the person
has stopped breathing. If you
think he is not breathing, place
him flat on his back. Put your ear
close to his mouth and look at his
chest. If he is breathing you can
feel the air on your cheek. You
can see his chest move up and
down. If you do not feel the air
or see the chest move, he is not
breathing.
2. If he is not breathing, open
the airway by tilting his head
backwards.
Lift up his neck with one hand
and push down on his forehead
with the other. This opens the
airway. Sometimes doing this will
let the person breathe again by
himself.
3. If he is still not breathing,
begin rescue breathing.
-Keep his head tilted backward.
Pinch nose shut.
-Put your mouth tightly over his
mouth.
-Blow into his mouth once every
five seconds
-DO NOT STOP rescue breathing
until help arrives.
LOOSEN CLOTHING -KEEP
WARM
Do this when the victim is
breathing by himself or help is
available. Keep him as quiet as
possible and from becoming
chilled. Otherwise treat him for
shock.
BURNS
SKIN REDDENED: Apply ice cold water to burned
area to prevent burn from going deeper into skin
tissue. Cover area with clean sheet or cloth to keep
away air. Consult a physician.
SKIN BLISTERED OR FLESH CHARRED: Apply ice
cold water to burned area to prevent burn from
going deeper into skin tissue.
Cover area with clean sheet or cloth to keep away
air. Treat victim for shock and take to hospital.
EXTENSIVE BURN -SKIN BROKEN: Cover area with
clean sheet or cloth to keep away air. Treat victim
for shock and take to hospital.
