11. Power Sources: This product should be operated only from the
type of power source indicated on the marking label. If you are not
sure of the type of power 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, other electric light or power cir-
cuits, 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 fol-
lowing conditions:
provide some protection against voltage surges and built-up static
charges.
a. Use No.10 AWG (5.3mm) copper, No.8 AWG (8.4mm) alu-
minum, No.7 AWG (10mm) copper-clad steel or bronze wire or
larger, as ground wire.
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.
b. Secure antenna lead-in and ground wires to house with stand-
off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
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 tech-
nician to restore the product to its normal operation.
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. If the product has been dropped or the cabinet has been
damaged.
e. Use jumper wire not smaller than No.6 AWG (13.3mm) copper
or equivalent, when a separate antenna grounding electrode is
used.
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.

The Pico Macom PCFM is a frequency agile professional re-broadcast grade,
microprocessor controlled Stereo/Mono Audio Modulator. Its phase-locked
loop frequency control and sharp two-stage bandpass filtering minimize
adjacent channel interference and assures accurate and spurious free output.
The PCFM provides up to 35dBmV output across the FM band (88-108 MHz).
The unit is easily tuned by using channel up/down buttons and the digital
display located on the front panel. Designed specifically for commercial instal-
lations, the PCFM provides superior signal-to-noise ratio, discrete left-and-right
audio signal separation, and enhanced dynamic range. Switchable
mono/stereo capability provides FM transmission versatility. The modulator is
shipped with all internal adjustments preset. Pico Macom backs up this
product with its industry leading 5-year limited warranty.

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
program 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 Service 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 new RMA number on the box and ship it back to us for 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 you, and must likewise receive the loaner unit within one week 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 addi-
tional information on qualifying equipment and procedures. Pico Macom reserves the right to modify or discontinue the Uptime Loaner Program at any time, and at
its sole discretion.
