SYSTEM OPERATION
Connecting the receiver
Prior to setting up, please check that the transmitter and receiver are tuned to the same channel. Two or more transmitters operating in the same channel can not be used at the same time and area.
| 1 |  |  Connected the provided DC power supply to the receiver power input with an appropriate AC power source. The LED display will light and the receiver is on. |
| 2 |  | Use a standard audio cable with 3-pin XLR connectors or 6.3mm phone plugs to connect the mixer or amplifier.
|
| 3 |  | Set the audio output level for MIC: -20dB LINE: 0dB (Default Setting) |
| 4 |  | Using the Volume Controller to adjust the AF audio level to the input of the amplifier or mixer.
|
Channel setting on the receiver
Notice: Do not put two or more transmitters operating nearby when setting up the channel.
Please keep the transmitter at least one meter away from the receiver.
Setting interference-free channel by manual operation.
 | Press the “Channel” button for 3 seconds till the LED display is flashing. |
 | Slight press the “Channel” button to change the channel forward. |
 | Press the “Channel” button for 3 seconds to lock the setting. If you do not press the “Channel” button for 3 seconds to lock the setting, the LED will keep flashing for a while and revert to the last set channel. |
Set up the handheld microphone/bodypack transmitter
Open the battery cover and insert batteries into the battery compartment conforming to the polarity (+)(-) marks.
Unscrew the handheld Mic and open the battery cover to insert the battery into the battery compartment and confirm the marks of the polarity (+) (-).
Connect to the lavalier microphone, headset microphone, or guitar cable.
NOTE: When you don’t use this device for a long-term period, please switch the power “off” in order to save more electricity.
Press for 1 second to turn the Handheld/Bodypack transmitter on.
If the LED stays flashing, it indicates that the battery will out of power soon and should be changed.
Adjust the audio input level.
- 0dB
- -10dB (Default Setting)
- -20dB
NOTE: When you don’t use this device for a long-term period, please switch the power switch to “off” mode to save more electric power.
Pairing a transmitter with a receiver
Automatic frequency synchronization via remote channel for easy setup.
First, switch the transmitter and the receiver on.

Trouble Shooting
| Problem | Solution |
| No sound | Check the power supply of the microphone and receiver. Check that the transmitter and receiver are tuned to the same frequency. Check whether the hi-fi appliance is switched on and the receiver output is connected to the audio mixer or amplifier input. Check whether the receiver is located too near a metal object or there are obstructions between transmitter and receiver. |
| Sound interference | Check the antenna location. When using 2 or above microphone sets simultaneously, make sure that the chosen frequencies do not interfere. Check whether the interference comes from other wireless microphones, TV, radio and etc. |
| Distortion | Check the receiver volume level whether is set too high or too low. Check whether the interference comes from other wireless microphones, TV, radio and etc. |
Safety
Do not spill liquid on the appliance and do not drop it on a hard concrete floor. Do not place the equipment near heat sources such as radiators, heating ducts, amplifiers, etc. Do not expose the equipment to direct sunlight, extremely dust, excessive moisture, rain, mechanical vibrations, or shock. Take out the battery from the transmitter, if the appliance has been not used for a longer period. This will avoid the damage resulting from a defective leaking battery. If the equipment is not going to be used for a long time, disconnect the AC adapter from the power outlet. Please note that if you turn the equipment off while leaving the AC adapter plugged in, it is not fully isolated from the power supply.WARNING: To reduce the risk of fire or electric shock, do not use the products near water and do not expose them to rain or moisture. No guarantee claims for the equipment and no liability for any resulting personal damage or material damage will be accepted if the equipment is used for another purpose than originally intended, if the equipment is not correctly connected or operated, or if the equipment is not repaired in an expert way.
Environment Do not throw used batteries into a fire or garbage bin with domestic rubbish. Be sure to dispose of used batteries in accordance with local waste disposal rules. When disposing of the equipment, remove the batteries, separate the case, circuit boards, and cables, and dispose of all components in accordance with local waste disposal rules.
