The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of un-insulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.

Safeguards
11. Power Sources: This product should be operated only from the
type of power source indicated on the marking label. If you are not
s
ure of the type of power supplied to your home, consult your appli-
a
nce dealer or local power company.
12. Power-cord Protection: Power-supply cords should be routed
s
o they are not likely to be walked on or pinched by items placed
upon or against them. Pay particular attention to cords and plugs,
convenience receptacles, and the point where they exit from the
appliance.
13.
Lightning:
For added protection for this product during a lightning
storm, or when it is left unattended or unused for long periods of time,
the unit should be disconnected from power source.
14. Power Lines: An outside antenna system should not be located
in the vicinity of overhead power lines, other electric light or power circuits, where it can fall into such power lines or circuits. When
installing an outside antenna system, extreme care should be taken
to keep from touching such power lines or circuits as contact with
them may be fatal.
15. Overloading: Do not overload wall outlets and extension cords
as this can result in risk of fire or electric shock.
16. Object and Liquid Entry: Never push objects of any kind into this
product through openings as they may touch dangerous voltage
points or short-out parts that could result in a fire or electric shock.
Never spill liquid of any kind on the product.
17. Servicing: Do not attempt to service this product yourself as
opening or removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service personnel.
18. Damage Requiring Service: Unplug this product from the wall
outlet and refer servicing to qualified service personnel under the
following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the product.
c. If the product has been exposed to rain or water.
d. If the product does not operate normally by following the oper-
ating instruction. Adjust only those controls that are covered by
the operating instructions. An improper adjustment may result in
damage and will often require extensive work by a qualified technician to restore the product to its normal operation.
e. If the product has been dropped or the cabinet has been
damaged.
f. When the product exhibits a distinct change in performance—
this indicates a need for service.
19. Replacement Parts: When replacement parts are required, be
sure the service technician has used replacement parts specified by
the manufacturer or have the same characteristics as the original
parts. Unauthorized substitutes may result in fire, electric shock or
other hazards.
20. Safety Check: Upon completion of any service or repairs to this
product, ask the service technician to perform safety checks to determine that the product is in proper operating conditions.
21.
Outdoor Antenna Grounding:
Before attempting to install this
product, be sure the antenna or cable system is grounded so as to
provide some protection against voltage surges and built-up static
charges.
a. Use No.10 AWG (5.3mm) copper, No.8 AWG (8.4mm) aluminum, No.7
AWG (10mm) copper-clad steel or bronze wire or
larger, as ground wire.
b. Secure antenna lead-in and ground wires to house with standoff insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
c. Mount antenna discharge unit as close as possible to where
lead-in enters house.
d. A driven rod may be used as the grounding electrode where
other types of electrode systems do not exist. Refer to the
National Electrical Code, ANSI/NFPA 70-1984 for information.
e. Use jumper wire not smaller than No.6 AWG (13.3mm) copper
or equivalent, when a separate antenna grounding electrode is
used.

Operating Guidelines
Below is a chart showing the proper operation level for the CA-30/870AR. Please note the listed performance criteria is
for SPECIFIC numbers of channels, and must be de-rated accordingly when inserting additional channels. Also note the
amplifier’s gain does not change. However, as the number of channels increases from 7 channels, the input level
(hence, the output level) must be reduced. Exceeding the input levels listed below will cause intermodulation and
picture distortions.

Installation
T
he output levels of all devices in a headend system, whether they be modulators, channel processors and/or strip
amps / BPF combinations must be the same prior to combining into the PHC-12G or PHC-24G. The output of the combiner is then connected to the input of the CA-30/870AR. The return path is utilized via a remote signal source, such as
a camera or DVD player, connected to a sub-band modulator and fed into the return path, which is then connected to
a sub-band channel processor.
The
PHC-12G twelve channel and PHC-24G twenty-four channel combiners consist of two rows of directional couplers
combined by a hybrid splitter. The directional coupler combining provides high isolation (40 dB) between the inputs.
Normally, the odd channels are combined on one row while even channels are combined on the other row of directional
couplers. The combiner loss is 18 dB per channel for the PHC-12G and 21 dB per channel for the
PHC-24G. The output of the amplifier is connected to the main distribution line.
