Features
• Equips your TV with A/V inputs
• Converts any A/V signal into coaxial cable output
1 Connect the Modulator
You need the following parts (not supplied) to connect
your modulator to a video input source and your TV:
• One A/V shielded cable. If your video source’s
audio output is stereo, use an A/V cable with
three phono connectors at each end. If your video
source’s audio output is mono, use an A/V cable
with two phono connectors at each end.
• Two 75-ohm coaxial cables with F-type connectors.
• One 75-ohm-to-300-ohm matching transformer
(only if your TV does not have a VHF 75-ohm
terminal).
• One S-Video cable (only if your video source has an
S-Video jack).

S-Video Cable or A/V Cable
To Stereo Video
Use a stereo A/V cable to connect your modulator to a stereo
video source. Connect one end of the cable to the modulator’s
VIDEO (yellow) and L/R AUDIO (white/red) jacks. Connect the
cable’s other end to your video source’s video and audio output
jacks.
To Mono Video
Use an A/V cable to connect your modulator to a mono video
source. Connect one end of the cable to the modulator’s
VIDEO (yellow) and AUDIO (white) jacks. Connect the cable’s
other ends to your video source’s video and audio jacks.
To S-video
If your video source has an S-Video jack, use an S-Video cable
to connect the modulator’s S-VIDEO jack to your video source’s
S-Video jack. If your video source is connected to both the
modulator’s VIDEO and S-VIDEO jacks, the modulator uses
S-video.

To TV
If your TV is already connected to a VHF input source (cable,
antenna, etc.), disconnect the VHF input source from your TV,
and connect its cable to the modulator’s ANT IN terminal.
Then, use a 75-ohm coaxial cable (not supplied) to connect
the modulator’s TO TV terminal to your TV’s 75-ohm VHF/UHF
terminal.
If your TV is not already connected to a VHF source, connect
a 75-ohm coaxial cable to the modulator’s TO TV terminal to
your TV’s 75-ohm VHF/UHF terminal. If your TV has 300-ohm
VHF screw terminals, use a 75-ohm-to-300-ohm matching
transformer to complete this connection.
When connections are complete, plug the modulator into a
standard AC outlet.
2 Use your Modulator
1. Turn on your TV and turn it to Channel 3 or 4 (the one
not used for regular broadcasts in your area).
2. Set the CHANNEL 3/4
switch on the modulator
to the same channel as
your TV.
3. Turn on the connected
video source. The

source from the modulator.
n Note: The modulator’s audio output is always
mono, even if the source’s audio is stereo.
Note to CATV System Installer: Article 820-22 of the
NEC 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.

5

serious injury to a child or adult, and serious damage to the
product. Use only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with the product.
Any mounting of the product should follow the manufacturer’s
instructions, and should use a mounting accessory
recommended by the manufacturer.
Ventilation — Slots and openings in the cabinet are provided
for ventilation, to ensure reliable operation of the product and
to protect it from overheating.The openings should not be
blocked by placing the product on a bed, sofa, rug, or other
similar surface. This product should not be placed in a built-in
installation such as a bookcase or rack unless proper ventilation
is provided or the manufacturer’s instructions have been
adhered to.
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 supply to your home, consult
your product dealer or local power company.
Grounding or Polarization — This product may be
equipped with a polarized alternating-current line plug (a plug
having one blade wider than the other). This plug will fit into
the power outlet only one way. This is a safety feature. If you
are unable to insert the plug fully into the outlet, try reversing
the plug. If the plug still fails to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the safety purpose
of the polarized plug.
Power-Cord Protection — Power-supply cords should be
routed so that they are not likely to be walked on or pinched by
items placed upon or against them, paying particular attention
to cords at plugs, convenience receptacles, and the point where
they exit from the product.
Protective Attachment Plug — The product is equipped
with an attachment plug having overload protection. This is a
safety feature. If replacement of the plug is required, be sure
6

the service technician has used a replacement plug specified by
the manufacturer that has the same overload protection as the
original plug.
Outdoor Antenna Grounding — If an outside antenna or
cable system is connected to the product, be sure the antenna
or cable system is grounded so as to provide some protection
against voltage surges and built-up static charges. Article
810 of the National Electrical Code, ANSI/NFPA 70, provides
information on proper grounding of the mast and supporting
conductors, location of antenna-discharge unit, connection
to grounding electrodes, and requirements for the grounding
electrode.
Lightning — For added protection during a lightning storm,
unplug the unit from the wall outlet and disconnect the antenna
or cable system. This will prevent damage to the product due to
lightning and power-line surges.
Power Lines — An outside antenna system should not be
located in the vicinity of overhead power lines, electric light or
power circuits, or where it can fall into power lines or circuits.
When installing an outside antenna system, take care to keep
from touching power lines or circuits. Contact with them might
be fatal.
Overloading — Do not overload wall outlets, extension cords,
or integral convenience receptacles as this can result in a risk of
fire or electric shock.

kind through product openings as they may touch dangerous
voltage points or short parts that could result in a fire or electric
shock. Never spill liquid of any kind on the product.
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.
