Introduction
Manual Overview
This manual contains the description of the Innovator CU10BT-CU5000BT ATSC
Transmitter and the circuit descriptions of the boards, which make up the system The
manual also describes the installation, setup and alignment procedures for the system
Appendix A of this manual contains the system level drawings for the Innovator
CU10BT-CU5000BT NTSC Transmitter Information and any drawings on OEM supplied
equipment are contained in the manufacturers supplied Instruction Manual
Assembly Designation Numbers
Axcera has assigned assembly numbers, Ax designations, where x=1, 2, 3 etc , example
A1, to all assemblies, modules, and boards in the system These designations are
referenced in the text of this manual and shown on the block diagrams and interconnect
drawings provided in the appendices The Block Diagrams, Interconnects, Schematics,
Assembly Drawings and Parts Lists are arranged in increasing numerical order in the
appendices Section titles in the text for assembly or module descriptions or alignment
procedures contain the associated part number(s) and the relevant appendix that contains
the drawings for that item
The cables that connect between the boards within a drawer or assembly and that
connect between the drawers, racks and cabinets are labeled using markers Figure 1-1
is an example of a marked cable There may be as few as two or as many as four
Markers on any one cable These markers are read starting farthest from the connector
If there are four Markers, the marker farthest from the connector is the system number
such as system 1 or translator 2 The next or the farthest Marker is the rack or cabinet
“A” number on an interconnect cable or the board “A” number when the cable is within a
drawer The next number on an interconnect cable is the Drawer location or Board “A”
number The marker closest to the connector is the jack or connector “J” number on an
interconnect cable or the jack or connector “J” number on the board when the cable is
within a drawer

head backwards
Lift up his neck with one
hand and push down on his
forehead with the other This
opens the airway Sometimes

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 a
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
