If your TV is not already connected to another
VHF source (antenna, cable TV, VCR, etc.), con-
nect the 75-ohm coaxial cable directly between
the

RF OUT

terminal on the RF Modulator and the

75-ohm VHF 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.

4. Plug the RF Modulator power cord into a stan-

dard AC outlet.
