Transmitter and Receiver should be keep on same channel(RCA or HDMI).

b. Keep IR Remote control frequency band F1/F2 should be same, normal F1 is 38KHz frequency band and F2 is 56KHz frequency band.
c. Since smart tv sender support two group av input, so transmitter signal input is AV1, then receiver signal output should be AV1.
d. Keep av transmitter and receiver was in the same channels, like transmitter was 01 channels, then receiver should be 01 channels. If for other Dial switch also should be same.
e. Keep both transmitter and receiver was in the same channels, then you can adjust the above function at receiver ends.
