AN NTRODUCTION aur RadioShack Video RF Modulator is designed ta convert the eparate audio and video signals (from a video camera, computer, ortable VCR, or satellite recei tor example) into VHF TV signais vat you can view on a TV set that has no A/V (Audio/Video) inputs. he FCC Wants You to Know his device complies with Part 15 of the FCC Rules, Operation is ubject to the following twa conditions: (1) This device may not cquse armtul interference, and (2) this device must accept any interference sceived, including interference that may cause undesired operation. our modulator might cause TV or radio interference even when itis perating properly. To determine whether your modulator is causing
\ interference, turn it off. If the interference goes away, your
\odulator is causing it. ry to eliminate the interference by:
* moving your RF Modulator away from the recaiver
* connecting your RF Modulatar to an outlet that is on a different electrical circuit from the receiver .
* contacting your local RadioShack store for help you cannot eliminate the interference, the FCC requires that you op using your AF Modulator. Changes or modifications not xpressly approved by RadioShack could void the user's FCC utharization to operate this equipment. 1EQUIRED PARTS he fattowing items (not supplied) are required to connect your RF lodulator to a video input source and your TV. one audia/video shiekled cable with three phono connectors at each end (RadioShack Cat. No. 15-1507), if the video source's audio output is stereo; or one audio/video shielded cable with two phono connectors at each end (Cat. No. 15-1504} if the video source's audio output is monaural
* two 75-ohm coaxial cables with F-type connectors
* a75-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 mano, whether the video source is stereo or monaural. Note to the CATV System Installer: This reminder is provided to call the CATV system installers 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 Figures 1-3 on page 2 illustrate typical configurations for video sources conversion.
* if your video source is stereo, plug the connectors an one end of a stereo A/V cable into the video and audio input jacks on the AF Modulater. 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 inte the video and audio input jacks on the AF Modulator (using either the AUDIO A or L jack). Plug the cable's other ends into the video and audio jacks on the video source. Connect 75-ohm coaxial cables to the RF Modulator following these guidelines:
MH your TV is already connected to another VEF ingut source
(such as cable, an antenna, or a VCR, for axampie), disconnect the VHF input source's 75-ohm cable from the TV's 75-ohm VHF/UHF terminal, and reconnect it to the RF Moduiator's ANT iN terminal, Then connect a 75-ohm coaxial cable between the TO TV terminal on the RF Modulater and the 75-ohm VHF/UHF terminal on your TV. iftyour 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. Note: if your TV has only 300-ohm VHF screw terminals, use a 75-ohm-to-300-chm matching transformer to complete the connection, When your connections are complete, plug the RF Modulator's power cord into a standard AC outlet.

Tum 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 Modulators CHANNEL 3/4 switch to the same channel you set the TV (3 or 4). 3. Turn on the connected video source and set OHMS 75/1K on the RF Modulator to the position that gives the best picture. The video signal indicator on the RF Modulator lights when the modulator is receiving a signal from an A/V source. lf your video source is super video(S-Video) source, plug the S-Video connector onto the S-VIDEO input on the RF Modulator by using a S-Video cable. The OHMS 75/1K switch must be set to the 75 ohms position when S-VIDEO input is used. Note:
You can not use both S-VIDEO input and VIDEO input at same time. Disconnect VIDEO input cable from the modulator or turn off the Video source when you use S-VIDEO input. CARE Keep the RF modulator dry; if it gets wet, wipe it dry immediately. Use and store the RF modulator only in normal temperature environ-
ments. Handle the RF modulator carefully; do not drop it. Keep the RF modulator away from dust and dirt, and wipe it with a damp cloth occasionally to keep it looking new. Modifying or tampering with the RF modulators internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. if your RF modulator is not performing as it should, take it to your local RadioShack store for assistance.
