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.

Importent Information con't

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. 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 or unused for long
periods of time, the unit should be disconnected.

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.

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

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 lead­in 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 ­40 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

CATV/TVCHANNEL

PICO MACOM INC., U.S.A.

Description

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

Installation Procedures

1. Electrical Connection:

Plug the power cord into 120 Vac, 60Hz electrical
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 but­tons on the front panel.
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.
d. After selecting the channel, slide the rear
display switch, on rear panel, to the OFF posi­tion. This will disable the front panel tuning
controls and turn off the LED display. The
channel you have selected will be stored in
memory.

camcorder or surveillance camera to an
ultraband CATV channel or a standard UHF
channel.

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. Do not select channels that are adjacent to a
CATV or an active off-air channel. In applica­tions using multiple modulators, do not set mod­ulators to adjacent channels, for example 20, 21,

22.

c. Do not select a channel on which a local TV
channel is being broadcast.

d. Caution: The lowest UHF frequencies, chan­nels 14-19, have also been assigned as a commer­cial communications band. A nearby transmit­tercould cause intermittent interference on these
channels.

3. RF Output Connections:

The CAM-35UNIVan be used for various
applications to modulate a signal source such
as a satellite receiver, VCR, laser disk player,
