RF Modulator
Your RadioShack Video RF Modulator is designed to convert the
separate audio and video signals from a video camera, computer,
portable VCR, or satellite receiver into VHF TV signals that you can
view on a TV set that has no A/V (Audio/Video) inputs. This means
you can use it to connect a DVD player to an older TV’s antenna/
cable input. The RF Modulator’s gold-plated jacks and terminals
assure the maximum reliability and the minimum signal loss.
THE FCC WANTS YOU TO KNOW
This device complies with Part 15 of the
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 it 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 RadioShack store for help
If you cannot eliminate the interference, the FCC requires that you
stop using your RF Modulator. Changes or modifications not
expressly approved by RadioShack could void the user’s FCC
authorization to operate this equipment.
REQUIRED PARTS
The following items (available at your local RadioShack store) 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
• one S-Video cable, if the video source has a S-Video jack
Note
: The audio output from the RF Modulator is always mono, even
if the source audio is stereo.
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.
CONNECTIONS
The diagrams on pages 2 and 3 illustrate typical configurations for
video sources conversion.
•
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
the 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.
•
If your video source has a S-Video jack
, use a S-Video cable to
connect the S-Video jacks on the RF Modulator and the video
source.
Note
: The RF Modulator selects S-Video as the first priority if
both
VIDEO
and
S-VIDEO
jacks are connected.
Connect 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 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
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 the
TO TV
terminal
on the RF Modulator and the 75-ohm VHF/UHF terminal on
your TV.
If your TV has only 300-ohm VHF screw terminals, use a 75-
ohm-to-300-ohm matching transformer to complete the
connection.
When your connections are complete, plug the RF Modulator’s
power cord into a standard AC outlet.
