Operation of Receiver
1.Install the antenna to receiver with correct frequency, the angle
between antenna and receiver should be vertical.
2.Connect the receiver power socket with the power adapter output
jack.
3.Press the power switch for 1.5 seconds, LCD backlight is light; this
indicator receiver power is on. Please adjust each channel's volume
knob to the proper position to turn on the corresponding transmitter,
RF LED indicator and TONE frequency LED will flash, it means
signal has been received. AF LED will flash when speak with
microphone transmitter. Hold the power switch for 2 seconds if you
want turn off the receiver.
4.Channel frequency setting:
a). Press set key one time, LCD will display the frequency setting,
user can press “UP” & “DOWN” key to set the frequency manual,
please press set key again to save the setting
b). Press set key two times to enter MODE setting, user can use
“UP”& “DOWN” key to select the CHANNEL and TUNE mode, in
CHANNEL mode frequency band is 250kHz, total 60 point, in
TUNE mode frequency band is 50kHz, total 300 point. User can
save the setting with “SET” key press.
c). Press set key three times to enter SQ setting. User can use “UP”
& “DOWN” key to select the SQ (-70~-95dBm), each step 5dBm,
and then press “SET” key to save the setting.
d). Short press set key to enter the setting menu and then long press
set key for 2 seconds to switch Channel A to Channel B setting.
( Other channels same setting method)
5.IR sync
a). Short press “UP” key one time to enter channel A or channel C IR
sync function.
b). Press “UP” key again for 2 seconds to enter automatically
frequency scanning and selecting, and then use transmitter IR
sensor aim at the receiver's IR port to transmit the parameter,
receiver will save the setting and exit automatically by any key
if the IR sync succeed

6.Volume adjustment: Please adjust the volume with the knob to the
proper position to get the best sound level.
7.RF PWR adjustment of microphone transmitter: We suggest low
level if the distance between receive and microphone transmitter
less than 20 meters to save the battery power, and high level if the
distance more than 20 meters.
(We have setting the frequency and channel before send the
products, please do not change the setting if unnecessary)

1.Open the battery cover and put into two pieces AA 1.5V batteries,
please make sure the battery polar is correct. (Note: Please don't
make the battery polar wrong, it would be damaged electronic
component inside the transmitter.)
2.Press power switch, the power indicator is light; it means
microphone transmitter work normally.
3.User can set the microphone volume with volume gain knob.
4.User can set the microphone transmitter RF power with the switch;
correct setting can save the battery power and reduce the influence.
5.Turn off the microphone with power switch for 1 second.
