Stereo RF Modulator 15-2525
www.radioshack.comSM
OWNER’S MANUAL — Please read before using this equipment.
Thank you for purchasing a RadioShack Stereo RF Modulator. Your modulator is designed to convert the separate audio and video signals from a video camera, computer, portable VCR, DVD player or satellite receiver into VHF TV signals that you can view on a TV set without Audio/Video (A/V) inputs. This means you can connect a DVD player to an older TV's antenna/cable input. The modulator's gold-plated jacks and terminals assure maximum reliability and minimum signal loss. The modulator has two sets of inputs (front/back) so you can connect two devices at the same time.
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.
