!

The lightning flash with arrowhead sym­bol, within an equilateral triangle, is in­tended to alert the user to the presence of
uninsulated "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.

IMPORTANT INFORMATION CONT'D

10. Grounding or Polarization - This video product is

equipped with a polarized alternating - current line plug (a plug
having one blade wider than the other). This plug will
the power

socket only one way. This is a safety feature. If you

fit into

are unable to insert the plug full into the outlet, try reversing the
plug. If the plug should still fail to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the safety purpose
of the polarized plug.

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 appliance 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, 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 and unused for
long periods of time, unplug it from the wall outlet.

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
operating 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.

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
stand-off 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.

NOTE TO THE CATV SYSTEM INSTALLER:

THIS REMINDER IS PROVIDED TO CALL THE CATV
SYSTEM INSTALLER’S ATTENTION TO ARTICLE 820 ­22 OF THE NEC THAT PROVIDES GUIDELINES FOR
PROPER GROUNDING AND, IN PARTICULAR, SPECI­FIES THAT THE CABLE GROUND SHALL BE CON­NECTED TO THE GROUNDING SYSTEM OF THE BUILD­ING, AS CLOSE TO THE POINT OF CABLE ENTRY AS
PRACTICAL.

The PR-3200 is an economic descrambler

compatible commercial satellite receiver
designed for SMATV systems. The unit has
been tested by General Instruments to meet all
VideoCipher® II performance requirements. The

Technical Operation

RF Input The PR-3200 receives either C-

Band or Ku-Band signals from a 950-1450 MHz
LNB or a 950-1750 MHz LNB. Typical installa­tions using 60 dB gain LNB's have -25 dBm
available a t the output of the LNB. T h e PR-3200
will operate at input levels ranging from -30 dBm
to as low as -60 dBm. A front panel signal strength
meter is provided. At full IF gain; a meter reading
of 2 corresponds to a -60 dBm input, a reading of

8 corresponds to an input of -30 dBm.

70 MHz IF The selected RF input signal is

converted to a 70 MHz Intermediate Frequency
(I.F.). The PR-3200 comes with a short I.F. jumper
cable that must be installed between the "I.F.
OUT" and the "I.F. IN" connectors on the back of
the receiver. Terrestrial interference traps may be
inserted in the loop should microwave interference
be encountered.

LNB Power Most commercial headend

systems consist of several receivers and
modulators. The PICO MACOM Satellite Signal
Processor SSP-10 provides the dual LNB power
and the amplified power divider for such
applications. The PR-18DC external power
supply is also available for single receiver
applications. The PR-18DC power cable plugs
directly into the back of the PR-3200 to provide
+18 VDC power for the LNB.

PR-3200 provides three video outputs configured
to interface with all known scrambling systems.
The standard 950 to 1750 MHz tuning range of
the PR-3200 allows direct compatibility for
international CCIR standards.

H/V Switching The PR-3200 provides

automatic H/V switching.

Channel Selection is phase locked loop

controlled with a digital display of channel
numbers.The receiver comes factory tuned for
standard 24 channel C-Band operation.

Ku Band Operation The PR-3200 may also

be used for Ku band signals by use of the video
invert rear panel switch.

Audio Subcarrier selection is made from the

front panel in one of two ways. A preset PLL
tuned 6.8MHz demodulator or variable tuned

5.0MHz to 8.0MHz demodulator can be selected.

Outputs Three v ideo outputs are provided on

the rear of the PR-3200. Video and audio output
levels are factory set for C-band operation. Level
controls are accessible from bottom of unit. One
video output is filtered and clamped for
unscrambled programming. The composite video
output is de-emphasized, un-clamped and un­filtered for VideoCipher® operation. The MAC
descrambler compatible flat video output is
unclamped, un-filtered and has no de-emphasis.
