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. Press the power button to turn on the receiver, the display and the power indicator are all lit.
2. Manually set channel / auto search button:
press, the channel light flashes for 3 seconds to automatically confirm.
automatically search and lock on the undisturbed channel in the actual working environment.

The searched channel automatically calculates a clean and undisturbed frequency, indicating that the
radio frequency signal of this channel is received. When the transmitter is on the same frequency as the
receiver, this indicator will light.
After the frequency of the transmitter and the receiver are synchronized, when speaking with the
microphone, it indicates that the audio signal from the transmitter of this channel is received. When the
transmitter and receiver are at the same frequency, this indicator will be on.
3. Transmitter’s infrared window facing the infrared window of the receiver and press the “SYNC” button.

Single-receiver Systems Setup:
① Touch “UP1/ AFS” button to change the frequency manually. Or Press this button 3 seconds and the
receiver will auto-scan and lock on to an open, interference-free frequency.
② Turn on the transmitter, to let the IR receiving window face to the receiver IR data transfer window, then
press Channel 1 “SYNC” button, the transmitter will receive the channel dada from the receiver,
simultaneously the LCD displays the same channel as the receiver Channel 1 .
③ Touch “UP2 / AFS” button to change the frequency manually. Or Press this button 3 seconds and the
receiver will auto-scan and lock on to an open, interference-free frequency.
④ Turn on the other transmitter, to let the IR receiving window face to the receiver IR data transfer
window, then press Channel 2 “SYNC” button, the transmitter will receive the channel dada from the
receiver, simultaneously the LCD displays the same channel as the receiver Channel 2.
Multiple-receiver Systems Setup:
① Make certain that all the transmitters are turned off, then turn on all the receivers.
② Same as the operation of “Single-receiver Systems Setup” to set up interference-free frequency for
each receiver.
③ Turn on one transmitter, to set up the frequency referring to “Single-receiver Systems Setup”.
④ Repeat this operation, meanwhile, please note that when you set up one transmitter, other transmitters
have to be kept away from this operation.
