USER'S MANUAL
COMPACT RF MODULATOR
INTRODUCTION
Your Video RF Modulator is designed to convert the separate audio
and video signals (from a DVD player, video camera, computer, or
gaming device) into VHF TV signals that you can view on a TV.
REQUIRED PARTS
The following items (not supplied) are required to connect your RF
Modulator to a video input source and your TV.
• one audio/video shielded cable with three phono connectors at
each end, if the video source's audio output is stereo; or one
audio/video shielded cable with two phono connectors at each
end if the video source's audio output is mono
• one 75-ohm coaxial cable with F-type connectors
• a 75-ohm-to-300-ohm matching transformer, if your TV does not
have a VHF 75-ohm F-connector input
Note: The audio signal will be modulated to mono, whether the
video source is stereo or mono.
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 par-
ticular, 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.
CONNECTIONS
Follow these steps to connect your RF Modulator.
1. If your video source is stereo, plug the connectors on one
end of a stereo A/V cable into the video and audio input
jacks on the RF Modulator. Plug the connectors on the
cable's other end into to video and audio output jacks on
the video source, using the color coding on the connectors
as a guide.
• If your video source is mono, plug the connectors on one end of an
A/V cable into the video and audio input jacks on the RF Modulator
(using either the AUDIO R or L jack). Plug the cable's other ends
into the video and audio jacks on the video source.
2. Connect the 75-ohm coaxial cables to the RF Modulator following
these guidelines:
• If your TV is already connected to another VHF input source (such
as cable, an antenna, or a VCR, for example), disconnect the VHF
input source's 75-ohm cable from the TV's 75-ohm VHF/UHF termi-
nal, and reconnect it to the RF Modulator's ANT IN terminal. Then
connect a 75-ohm coaxial cable between the TO TV terminal on the
RF Modulator and the 75-ohm VHF/UHF terminal on your TV.
• If your TV is not already connected to another VHF source, connect
a 75-ohm coaxial cable between to the TO TV terminal on the RF
modulator and the75-ohm VHF/UHF terminal on your TV.
Note: If your TV has only 300-ohm VHF screw terminals, use a 75-
ohm-to-300-ohm matching transformer to complete the connection.
3. Plug the RF Modulator's power adapter into a standard AC outlet
and plug the adapter output cable into the modulator. Note: This
power unit is intended to be correctly oriented in a vertical or floor
mount position.
OPERATION
1. Turn on the TV and set it to either Channel 3 or 4. whichever is not
used for regular broadcasts in your area.
2. Set the RF Modulator's CHANNEL 3/4 switch to the same channel
you set the TV (3 or 4).
