“ TUNE “ button for best tuning reception.
b). Once the frequency is jammed, select another channel on the transmitter, then press
“ TUNE “ button again.
7. Switching Off
a) For protection of the transmitter and power saving, the transmitter will cut off
automatically if there is no/weak operation input signal from audio source for 4 minutes. In
