Caution
1. Correctly load the batteries to avoid damage.
2. The system has been adjusted precisely. Do not disassemble it to avoid problem.
3. Do not put system in dust, moisture, high temperature or strong magnetic filed environment to
avoid affecting the system lifespan.
4. Use standard batteries only. The betteries of low quality or low power lead to chemical material
leakage and internal parts damaged.
5. If the system will not be used for a long time, take the batteries out.

Application
Specification
1. Connect the supplied transformer with the DC power input connector of the transmitter.
2. Use the audio cable to connect with the audio input connector of the transmitter, and then with
the audio output equipment.
3. Turn on the transmitter power switch. if the power LED lights up, this means it works normally.
4. Open the battery compartment cover on the receiver, and load two AA batteries in.
5. Insert the earphone plug into the earphone connector of the receiver.
6. Turn on the receiver power switch. If the power LED lights up, this means it works normally. (At
this time, if the power LED ⑨ lights up red, this means it is in the operating status. If the power
LED lights up weakly, this means the low battery voltage.)
7. Adjust the channel switch to match the transmitter frequency with the receiver frequency.
8. Adjust the receiver volume knob to achieve wanted sound quality.
Operation Instruction
Trouble Shooting
No sound
Turn on the power
switch and the LED
does not light up
The receiver receives
the sound from other
system.
Low power voltage.
The receiver volume is not
increased.
The transmitter and audio source
are not correctly connected.
The receiver is too far from the
transmitter, and the receiver
automatically turns on the mute
function.
Operate in the operating range
instructed in the user manual.
The power supply is not
connected well.
Check if the transformer plug is
connected with the DC input
connector of the tramsmitter.
The batteries are loaded reversely.
Load the batteries correctly.
The frequencies are not matched. Set the channel adjusting switch
to keep the same frequency of
transmitter and receiver.
The transmitter frequency value
is close to that of other system.
Set the frequency of transmitter
and receiver to another frequency.
Problem Reason Trouble Shooting
The transmitter is not turned on.
The reciever is not turned on.

⑦ Antenna;
⑧ Channel adjustment: turn the switch and CH123 switches to the needed channel.
⑨ Receiver power LED: when the receiver is turned on, it lights up red. This means enough
battery power. When the LED lights up weakly, this means the low battery power. It needs
to replace the battery.
⑩ Earphone connector;
⑪ Power switch/volume adjustment;
⑫ Battery compartment: it loads two AA batteries.
⑬ Belt clip;
Turn on the transmitter.
Turn on the receiver.
Replace the battery.
Increase the receiver volume.
Reconnect with the audio source.
