Receiver Installation Method
03
Installation:
① For better operation the receiver should be at least 3ft (1m). above the ground and at least 3ft (1m).
away from a wall or metal surface to minimize reflections.
② Attached a pair of UHF antennas to the antenna input jacks, the antenna are normally positioned in the
shape of a “ V ” (both 45° from vertical) for best reception.
③ Keep antennas away from noise sources such as computer, digital equipment, motors, automobiles
and neon lights, as well as away from large metal objects
④ Keep open space between the receiver and transmitter for better reception.
⑤ The transmitter should be at least 6ft (2m). from the receiver

1. After connecting the antenna and the power cable, press the power button to turn on the
receiver. When the display is lit, the power is turned on successfully. (As shown below)
2. Long press “ ” button on the receiver to enter Automatic Frequency Search (AFS) function.
(As shown below)

P21 P22
The searched channel automatically calculates the interference-free frequency. The “RF” light on the
receiver display is 0 grid. If not, you can repeat this action until a clean channel is found. (As shown
below)
3. The transmitter’s infrared window facing to the receiver IR port. Press the “SYNC” button. (As
shown below)
Frequency alignment<15cm(6 in)
The frequency of the transmitter and the receiver are synchronized. When talking with the
microphone, the “AF” signal in the display jumps to indicate that there is an audio output. (As
shown below)
