EXAMPLE OF ANTENNA GROUNDING ACCORDING TO
NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED
IN ARTICLE 810 - "RADIO AND TELEVISION
EQUIPMENT"
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 fit into the power socket
only one way. This is a safety feature. If you are unable to insert the
plug full into the outlet, try reversing the plug. Ifthe plug should still
fail to fit, contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.

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.
19. ReplacementParts-Whenreplacementpartsarerequired,besurethe
service technician has used replacement parts specified by the manufac-
turer or have the same characteristics as the original parts. Unauthorized
substitutes may result in fire, electric shock or other hazards.
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 power lines or circuits as contact with them
may be fatal.
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.
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.
a. Use No.10 AWG (5.3mm ) copper, No.8 AWG (8.4mm (alumi-
num, 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.
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.
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.
18. DamageRequiringService-Unplugthisproductfromthewall
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 controlsthat 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.
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.
NOTE TO THE CATV SYSTEM INSTALLER:
THIS REMINDER IS PROVIDED TO CALL THE CATV

Description
channel number is displayed in the channel selection
window. Non-volatile memory locks and holds the
selected channel in case of the loss of input power.
The agile design provides maximum flexibility while
allowing installers to maintain an inventory of only
two models to cover all NTSC channels. The CAM-
35UNIV also supports HRC and IRC offsets and BTSC
audio.
The CAM-35UNIV modulates a video and Left
& Right audio signal of a VCR, satellite receiver
or security camera to a user selected TV channel.
The modulator has a double sideband, 35 dBmV
output that is free from spurious distortions. The
microprocessor con-trolled Phase Lock Loop
(PLL) circuitry allow selection of the output
channel to be made from the front panel. The selected

Installation Procedures
1. Electrical Connection:
camcorder or surveillance camera to an
ultraband CATV channel or a standard UHF
channel.
Plugthepowercordinto120Vac,60Hzelectrical
outlet.
2. Video and Audio Input Connections:
a. Slide the rear display switch to the ON
position. This switch activates and deactivates
the digital display and the channel selector but-
tons on the front panel.
4. Channel Selection Guidelines:
a. The CAM-35UNIV modulator converts your
input source to either UHF or Cable (CATV)
channels. Be sure your television set is tuned
properly for off-air or cable reception.
b. Connect in the audio and video plugs from
the input source to the AUDIO in and VIDEO in
jacks respectivily. For sources with only one
audio output, connect to either the right or left
jack.
c. Using the two front panel controls, select a
channel between 14 and 69 for off-air or 37 to
125 for CATV. NOTE: The modulator's LED
displays either off-air UHF or cable (CATV)
channels.
b. Do not select channels that are adjacent to a
CATV or an active off-air channel. In applica-
tions using multiple modulators, do not set mod-
ulators to adjacent channels, for example 20, 21,
22.
c. Do not select a channel on which a local TV
channel is being broadcast.
d. After selecting the channel, slide the rear
display switch, on rear panel, to the OFF posi-
tion. This will disable the front panel tuning
controls and turn off the LED display. The
channel you have selected will be stored in
memory.
d. Caution: ThelowestUHFfrequencies, chan-
nels14-19, havealsobeenassignedasacommer-
cial communications band. A nearby transmit-
tercould cause intermittent interference on these
channels.

3. RF Output Connections:
Once connections have been make and the de-
sired channel has been selected, installation of
the CAM-35UNIV is complete.
The CAM-35UNIVan be used for various
applications to modulate a signal source such
as a satellite receiver, VCR, laser disk player,
