OPERATION OF THE RECEIVER
1. Pull out both antenna A & B perpendicular to the machine. 2. Power connection to DC 12-17V socket.
3. Connection of audio output:
Mix output: Insert one end of the audio cable into the "BALANCED" socket, with the other end from the audio amplifier or mixer going into the "MIC IN" or "AUX IN" socket. Separate output: Insert one end of the audio cable into the "AUDIO OUT" socket for one of the channels, with the other end from the audio amplifier or mixer going into the
"MIC IN" or "AUX IN" socket. Application for the second is the same.
4. Press the power button. The power indicating light will switch on. 5. When the microphone on, you are able to adjust the frequency using the frequency up and down buttons. Once the frequency has been selected, press function set (shown on diagram for header V-A(receiver) on the following page) to confrm your selection, sending the signal to the microphone through the ACT. Once the connection is estabished correctly. The RF level will display. Attention when you install of the receiver
It should be placed than 1 meter from the floor.
It should be placed than 1meter away from any walls. Antennas must be fully extended for maximum signal reception.
