Features

Connecting your RF Modulator

1

 Connect a composite AV cable (not included) from 

the AV output jacks (yellow for video; red and white 
for stereo audio) of the source component 
(Blu-ray/DVD player, gaming system, etc.) to the 
corresponding color-coded input jacks on the 
RF Modulator.

 

Note:

 For mono AV components, use only the yellow and 

white connectors of the composite AV cable.

2

 Connect the coaxial cable to the TV using one of the 

following methods that matches your setup:

  •  If you have an RF TV source, such as a cable/satellite

   box or TV antenna, connected to the TV, disconnect 
   that component from the TV and connect the coaxial
   cable to the 

ANT IN

 jack on the RF Modulator. 

   Connect a separate coaxial cable from the 

TO TV

 

   jack on the RF Modulator to the RF input jack on the TV.

  •  If you do not have an 

RF TV

 source, connect a

   coaxial cable from the 

TO TV

 jack on the 

   RF Modulator to the RF input jack on the 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.
