the microphone transmitter in different location, it will cause the receiver antenna 1 and
antenna 2 receives the signal intensity changes, then function with automatic selection
information of the receiver will automatically switch to the reception signal strength channel
connected to the receiving system to ensure the best working condition, effectively
overcome the reception “blind spot” problem.
4, Volume: Output volume control knob, clockwise volume increase, counterclockwise

The trick of getting best sound effect
Transmitter face to receiver antenna, no barrier in the middle.
Receiver and antenna must be far away from large metal equipment.
To avoid the rotation of receiver near computer or other RF equipment.
To avoid the rotation of receiver under audio equipment, unless antenna is placed over a
long distance.
Use the correct receiver antenna.
