RF Connection – for TV without A/V Input Jacks
If there is no A/V input jacks on your TV, you will need to get an RF
modulator (available at your local electronics store) to make the
connection between TV and receiver. See Fig. 8.
Connection through an A/V Component
If an A/V component (VCR, DVD player, DBS receiver, and etc.) is
connected to the TV already, you can just connect the receiver to the
free LINE IN jacks on the A/V component. See Fig. 9.
