USER'S MANUAL
VIDEO/AUDIO RF MODULATOR
NOTE TO CATV SYSTEM INSTALLER:
INTRODUCTION
Your Video RF Modulator is designed to convert the separate audio and
video signals (from a video camera, computer, portable VCR, or satellite
receiver, for example) into VHF TV signals that you can view on a TV set.
The FCC Wants You to Know
This device complies with Part 15 of FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may
cause undesired operation.
Your modulator might cause TV or radio interference even when is
operating properly. To determine whether your modulator is causing the
interference, turn it off. If the interference goes away, your modulator is
causing it.
Try to eliminate the interference by:
• moving your RF Modulator away from the receiver
• connecting your RF Modulator to an outlet that is on a different
electrical circuit from the receiver
• contacting your local store for help
If you cannot eliminate the interference, the FCC requires that you stop
using your RF Modulator.
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 monaural,
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. Connect
the 75-ohm coaxial cables to the
RF Modulator following these
guidelines:
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's FCC authorization to
operate this equipment.
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 monaural
• two 75-ohm coaxial cables with F-type connectors
• a 75-ohm-to-300-ohm matching transformer, if your TV does not have
a VHF 75-ohm F-connector
Note: The audio signal will be modulated to mono, whether the video
source is stereo or monaural.
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.
• If your TV is already connected
to another VHF input source
(such as cable, an antenna, or a
VCR, for example), disconnect
Video Source
the VHF input source's 75-ohm
cable from the TV's 75-ohm
VHF/UHF terminal, 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
A/V Cable
the 75-ohm VHF/UHF terminal on
your TV.
RF Modulator
• If your TV is not already
connected to another VHF source,
Video Source
connect a 75-ohm coaxial cable
between to the TO TV terminal on
the RF modulator and the 75-ohm
VHF/UHF terminal on your TV.
A/V Cable
Note: If your TV has only 300-
RF Modulator
ohm VHF screw terminals, use
a 75-ohm-to-300-ohm matching
transformer to complete the
connection.
2. Plug the RF Modulator's
power cord into a standard
AC outlet. Note: This power
unit is intended to be correctly
oriented in a vertical or floor
mount position.
