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 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.

Innovator CU10BT-CU5000BT Analog Transmitter System Description

System Description

Depending on the model, the output power level is 10, 60, 100 or 200 Watts
Peak Sync plus Sound using a single Drawer, 600 or 1200 Watts using an
additional single amplifier Drawer, 2500 Watts with two Amplifier Drawers, 3700
Watts with three Amplifier Drawers, or 5000 Watts with four Amplifier Drawers.
The Innovator CXB Series system provides linear and nonlinear correction
capability for the transmission path.

The Drawer contains (A1) Analog Modulator board (1312264), (A3) the IF
Precorrector Board (1308796), (A4) the Frequency Agile Upconverter (1309695),
and (A6) the Amplifier Assembly. The (A7) Output Detector Board (1308685 or

1312207), (A8) the Innovator CX Control Board (1312543), (A9) the +5V, ±12V
Power Supply and (A10) the +24V/+28V/+32V/+39VDC Power Supply are also
contained in the Drawer.

The type of (A6) Amplifier Assembly used in the Drawer changes as the output
power of the system changes. The Amplifier Assembly (1309621) is used in
CU10 systems, the Amplifier Assembly (1312566) is used in CU60 and CU100
systems and the Amplifier Assembly (1312191 or 1315381 w/888A devices) is
used in CU200 systems.

The (A10) Power Supply Assembly also changes as the output power of the
system changes. A +24V Power Supply is used in CU10 systems, a +28V/300W
Power Supply is used in CU60 Systems, a +36V/600W Power Supply operating at
30V is used in CU100 systems and a +48V/1100W Power Supply operating at
39V or 48VDC is used in CU200 systems.

The IF output of the modulator board connects to J2 on the IF pre-corrector
board (1308796). The IF Pre-Corrector Board provides ALC, automatic or
manual, gain control of the IF level. The board also supplies pre-correction
Response, In Phase and Quadrature Non-Linear adjustments. The board has the
circuitry for ALC Fault, Input Fault and Modulation Fault monitoring and
indications. The IF is connected to the upconverter board (1309695) that takes
the 44 MHz or 36 MHz IF signal and converts it to a TV channel frequency in the
range of 54-860 MHz.

The RF on channel signal is fed to the ALC Board, Innovator CXB Series
(1308570), which is used to control the drive power to the RF amplifier chain in
the CU5, CU30, CU50, CU100 and CU200 Transmitters. In a CU60 or CU100, the
RF is connected to the (A6) Amplifier Assembly (1312566) that is made up of
(A6-A1) the 2 Stage UHF Amplifier Board (1308784) and (A6-A2) the RF Module
Pallet, High Output (1309580). The assembly has approximately 36 dB of gain.
The amplified output connects to the (A7) Output Detector Board (1312207)
which provides forward (2V=100%) and reflected (2V=25%) power samples to
the CU Control Board (1312543) for metering and monitoring purposes. An
output power sample is also supplied to the front panel sample jack J15, which is
a 50 Ohm BNC type. The typical sample value is approximately 60dB down from
the output power level of the Drawer. The RF output is cabled to J2 the “N”
connector RF output jack on the rear panel of the Drawer. In CU10, CU60,
CU100, and CU200 systems the output connects to a mask filter and then the
antenna for your system. In larger systems with one external PA, the RF output

Innovator CU10BT-CU5000BT Analog Transmitter System Description

Drawer. In CU2000 and higher power systems the RF is connected to a splitter
and then to the inputs of the CU1000 amplifier Drawers.

The CU500 system is made up of a CU100 Drawer and a 500 Watt Amplifier
Drawer. The CU100 is used as a driver that connects to the 500 Watt Amplifier
Drawer and supplies the needed drive level to produce the 500 Watts output of
the system. The control and operating parameters of the 500 Watt Amplifier
Drawer are displayed on the LCD Screen on the CU100 Drawer. In the CU500,
the RF input signal at J1 on the amplifier heatsink assembly is fed to J3 on the
LDMOS amplifier pallet. The amplified output of the pallet, which has
approximately 15 dB gain, is connected to the coupler board before it is cabled to
J2 the RF output jack of the Amplifier Heatsink Assembly. The coupler board
supplies a forward and a reflected power sample to the amplifier control board for
metering and monitoring purposes.

The CU1000 system is made up of a CU100 Drawer and a 1000 Watt Amplifier
Drawer. The CU100 is used as a driver that connects to the CU1000 Amplifier
Drawer and supplies the needed drive level to produce the 500 Watts output of
the system. The control and operating parameters of the 1000 Watt Amplifier
Drawer are displayed on the LCD Screen on the CU100 Drawer. In the CU1000,
the input RF signal at J1, located on the rear panel of the Drawer, is fed to J1 on
the 4 Way Splitter Board, which supplies four outputs, one to each 878 amplifier
pallet. Each amplifier pallet has approximately 14 dB gain. The amplified
outputs of the pallets are combined in the 4 Way combiner board whose output is
at J1. The RF is connected to J2 the 7/16” (1.1cm) Din RF output jack located on
the rear panel of the Drawer. The 4 way combiner board supplies a forward and
a reflected power sample to the amplifier control board for metering and
monitoring purposes. In a CU1000, the typical sample value at J6, a 50Ω BNC
jack located on the front panel of the Drawer, is approximately 65dB down from
the output power level of the Drawer.

In higher power systems, multiple amplifier Drawers are used along with splitters
and combiners to produce the desired output. A System Metering Board
(1312666) provides forward, reflected, overtemperature and other parameters to
the exciter/driver Drawer from the external power amplifier chain. The CU2000
is made up of a CU100 driver Drawer, a two way splitter, two CU1000 amplifier
Drawers and a two way combiner with a 500W reject load. The reject load
provides isolation protection of the operating power amplifier if the other
amplifier fails. One–half the power of the operating amplifier Drawer connected
to the combiner will be dissipated by the reject load with the other half of the
power going to the output filters and the antenna. The CU3400 is made up of a
CU100 driver Drawer, a three way splitter, three CU1000 amplifier Drawers and a
three way combiner with reject load. The CU5000 is made up of a CU100 driver
Drawer, a four way splitter, four CU1000 amplifier Drawers and a four way
combiner with reject load.

The On Channel RF output of the amplifier Drawer either connects directly to the
low pass filter and the mask filter then to the antenna in single amplifier systems
or to a combiner, the low pass filter and a mask filter and finally to the antenna
in multiple amplifier systems.

AC Input Connections

Refer to Figures 3 and 4 that follow for the location of the jacks and connectors of the system.
The CU10, CU60, and CU100 single Drawer systems will operate with an input voltage of 85­253VAC. CU200 single Drawer systems operate on 185-253VAC. The customer should provide
a single point breaker or disconnect for the main AC input connection to the transmitter. Check
that the AC switch, located on the rear of the Drawer above the AC power jack, is OFF.
Connect the AC power cord supplied with the Drawer from J6 on the rear of the Drawer to the
AC source.

If your system is a CU500 or CU1000, it also contains one 500 Watt or 1000 Watt amplifier
Drawer. In CU2000 and higher power systems, multiple 1000 Watt amplifier Drawers are
included. Each amplifier Drawer is configured for 230 VAC operation only. Check that the
ON/OFF circuit breakers, located on each side of the AC power jack, are OFF. Connect the AC
power cord supplied with the Drawer from J10 on the rear of the Drawer to the 230 VAC source.
Refer to Table 1 for the typical voltage and current requirements for CXB Systems.

If the system is mounted in a cabinet, an AC distribution panel is used to connect the AC to the
individual Drawers. The AC distribution panel is mounted facing the rear of the cabinet and
accessed through the back of the cabinet. The main AC input for a CU2000BT transmitter is,
195-235VAC, at least 30Amps, 50/60Hz. The customer should provide a single point breaker or
disconnect for the main AC input that connects to the transmitter. The AC input lines connect
to the AC distribution panel by first removing the four #8 screws that hold the cover plate to
the front of the AC distribution panel. Then connect the three wire main AC input to the input
lugs located at the top left of the AC distribution panel, L1 to L1, L2 to L2 and Ground to the
Ground lug on the left.

The AC distribution panel has three circuit breakers that distribute the AC to the individual
Drawers, which are the Exciter and the two power amplifier Drawers, in the system. The circuit
breakers, which are accessed through the rear door of the cabinet, supply the AC though AC
line cords, that connect to the AC input jacks mounted on the rear panels of the Drawers. CB1
is a 30 Amp circuit breaker which supplies the AC to the (A2), top, Power Amplifier A Drawer.
CB2 is a 30 Amp circuit breaker which supplies the AC to the (A3), bottom, Power Amplifier B
Drawer. CB3 is a 10 Amp circuit breaker which supplies the AC to the (A1) Exciter/Driver
Drawer. The circuit breakers are accessed through the rear door of the cabinet.

filter, the mask filter and then to the antenna for your system in single amplifier systems or
to a combiner and then the low pass filter, the mask filter and finally to the antenna in
multiple amplifier systems.

Maintenance

Innovator CXB Series Transmitters are designed with components that require little or no
periodic maintenance except for the routine cleaning of the fans and the front panels of the
modules and the periodic check of general tightness of hardware.

It is recommended that periodically, the time interval depends on the amount of movement the
cabinet receives, all mounting hardware, holding drawer slides, shelving and mounting plates
inside the cabinet are checked for tightness. All screws and bolts that are accessible should be
tightened initially when the transmitter is received and periodically thereafter if the transmitter
is moved by vehicle. All coaxial connectors, hard-line connections and hardware holding
combiners, splitters, or any other mounted items should be checked and tightened. The
amount of time between cleanings of the drawers and cabinets 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
drawer. When the front panels of the drawers become dust covered, the drawer should be
pulled out and any accumulated foreign material should be removed. NOTE: To remove the
CXB series transmitter from the cabinet, the input and output cables must be removed from the
rear of the transmitter before the drawer can be pulled out completely from the cabinet.

A vacuum cleaner, utilizing a small, wand-type attachment, is an excellent way to suction out
any dirt from the drawer and cabinet. 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 drawers 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
transmitter be recorded from the LEDs and the LCD system metering on the front panel of the
drawer at least once a month to be used for comparison purposes in case of a failure. It is
suggested that this data be retained in a rugged folder or envelope and stored near the
transmitter.
