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. Make sure the transmitter is off before turning on the receiver.
2 Press the power switch on the receiver, LCD backlight will turn bright, and the normal display will be in 1-2
seconds. If the screen shows more than two signals, which means that there is a frequency interference
from outside, please change the other operating frequency.
3 Change the operating frequency by manual or by auto-scan mold:
a) Set the operating frequency by manual: press ◄/► to change the frequency, after the selected frequency
fleshes 4 times, the receiver will enter the selected frequency and show it on the LCD screen.
b) AFS Auto Frequency Scanning: long press ◄/► or 3 seconds, the receiver will auto scan about 30
seconds and lock on to an interference-free frequency.
4 Enter the main menu: long press SET button 3 seconds to enter the main menu. Press ◄/► button to select

button to select any group of 01-10, Finally press SET to confirm.
(3) LEVEL (electrical level adjustment -06 ~ +18dB): select LEVEL, then press SET to enter the edit
mode, press ◄/► button, the adjustable electronic volume (-06 ~ +18dB). Finally press SET to confirm.
(4) SQELCH (squelch level control):
small data flashes to indicate edit, touch ◄/► button to scroll through the available choice for the
function. The squelch level is adjustable in ten 5dB steps, providing a 50dB range. Press SET Button to
confirm the desired choice, then LCD return to its previously displayed contents. Finally press “SET” to
confirm.
(Receiver squelch threshold is factory preset. When the transmitter too far away from the reception
range or receiver does not receive enough transmit power, you can adjust by yourself. Note that unless
absolutely necessary, please do not adjust the squelch threshold, if adjusted too low will produce
excessive noise, system operation will not stable.)
(5) :
button, it displays “ON”, if stopping on “ON”, the system enters lock mode, the user can not use any
button for any control; touch ► arrow button, it displays “OFF”, if stopping on “OFF”, the user can do any
control by any button. Press SET (LOCK ON)status, long press SET button 3 seconds, press ◄/►
button to select LOCK, then press ► , the screen freshes OFF, finally press SET to confirm, the lock
status is released.

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)

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
