Safeguards
11. Power Sources: This product should be operated only from the
type of po
wer source indicated on the marking label. If you are not
sure of the type of po
wer supplied to your home, consult your appli-
ance dealer or local power company.
12. Power-cord Protection: Power-supply cords should be routed
so they are not likely to be walked on or pinched by items placed upon
or against them.
Pay particular attention to cords and plugs, conven-
ience 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 or 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 an
y ser
vice or repairs to this
product, ask the service technician to perf
or
m saf
ety chec
ks to deter-
mine 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.

The Pico Macom CA50/550 is a high quality push-pull w
all-mounted
distribution amplifier producing signals with extremely low-noise and
harmonic distortion. This amplifier is capable of 82 channel operation
over the 54-550MHz range, and makes an excellent distribution system
in MDU, CATV, and SMATV systems. Because of its extremely low-noise
figure and low distortion, the CA50/550 is ideally suited for use in larger
networks where amplifier cascading is required.

Installation
The output levels of the modulators should be the same as the output of the off-air strip amplifiers. The M860 modulators are usually combined with either the SP860 signal processor or LBS/MBS/FMS/UBS series.
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 (40dB) 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
amplifiers, are connected to the
main distribution line.
Another method of combining signals uses three hybrid splitters per headend rack.The odd channels are combined
in one splitter, the even-channels in another splitter and the two or more splitters are combined to a single output
with a third splitter. Each rack is then combined with a final splitter prior to the
CA50RK550 post amplifier.

Uptime Loaner Program
Our Uptime loaner program is designed to provide domestic users of our headend products and commercial systems the best possible support and service. This
prog
r
am is established to minimize downtime resulting from equipment failure in critical service situations. We offer this program free-of-charge (excluding freight)
to qualified purchasers within the warranty period. The program provides a free equipment loan of like qualified equipment enabling seamless operation for the time
required to repair and return the unit.
The process is simple
.
Call our Customer Ser
vice desk requesting a return-merchandise-authorization (RMA) number for the failed equipment and ask for a loaner
unit. We will issue an invoice for the List Price of the loaner unit plus shipping costs. When you receive the loaner unit, pack the failed unit in the loaner unit’s box
and ship it freight prepaid to Pico Macom for repair. When you receive the repaired unit, a new RMA number will be provided in the box. Carefully pack the loaner
unit and affix the ne
w RMA n
umber on the bo
x and ship it bac
k to us f
or full credit excluding shipping costs.
To qualify for the program, you must have current open-terms with us and in good standing. We must receive your failed unit within one week after the loaner unit
is shipped to y
ou, and m
ust lik
e
wise receiv
e the loaner unit within one w
eek after the repaired unit is shipped back to you. Daily rental fees not to exceed 10% of
the equipment’s List Price will apply beyond one week after the loaner or repaired unit are shipped to you. Other limitations may apply, so please call us for additional inf
or
mation on qualifying equipment and procedures. Pico Macom reserves the right to modify or discontinue the Uptime Loaner Program at any time, and at
