**Wireless smart induction wireless charging all-in-one receiver

operation**

1. Automatic search for idle channels In a complex environment, it takes time to manually select channels without interference. The new system is equipped with an automatic search for interference-free channels.
   The operation method is as follows:
   Press the “SCAN” key, the host enters the automatic search for non- interference channel function, when the host searches for a non-interference channel, it will flash and display Currently searched for a non-interference channel, turn on the hand microphone at this time, align the position of the hand microphone’s display with the host’s “IR” launch window, and press The “SET” button can be used to perform infrared pairing operations.

2. Lock and unlock the host Press the A channel and B channel “SET” keys at the same time, the display is the locked state, and press the A channel and B channel “SET” keys at the same time again to display the state.

3. Manual FM setting Long press the SET button, then press the VOL+ button or VOL- button to adjust the frequency point up and down. After the adjustment is completed, press the IR button to perform infrared frequency binding.

Note: since each frequency point has its own encryption algorithm, the host can only use the same frequency points as the last successful frequency matching. If it appears, the frequency points displayed by the hand and the host are the same, but if the host has any signal or no sound, it can be operated again.

Operation methods and precautions

Operation method

1. Connect the whole sound system;
2. Adjust the volume of receiver and loudspeaker (karaoke power amplifier) to the minimum position;
3. Turn on the power supply of the whole sound system according to the order from the front stage to the back stage;
4. Turn on the power supply of the transmitter;
5. Adjust the sound effect of the whole sound system: first, adjust the volume potentiometer of the receiver to the mid point position (for example, the receiver with the concealed potentiometer has been adjusted in the middle position when leaving the factory), turn on the microphone switch, speak to the microphone to make the volume appropriate, and then adjust the volume and volume controller carefully to make the sound clear and the volume appropriate. If necessary, take the microphone to carry out the “walking field” test in the whole use site. Generally, it is appropriate that the microphone does not produce howling during the whole “walking field” process;
6. If there is a problem with the wireless receiver system, please refer to this manual for troubleshooting and solve the problem. If not, please ask professionals to solve the problem or directly negotiate with the dealer;
7. After use, turn off the power supply of the transmitter first, and then turn off the power supply of the whole audio system according to the order from the previous level.
8. The receiver has a built-in charging module. When the host is turned off, the transmitter can still be charged when the power is connected. 9. When the microphone is charged, the charging sign will flash, and when the microphone is fully charged, the charging mark will stop flashing;

matters needing attention

1. The installation position of the antenna directly affects the receiving effect of the receiver, so pay special attention to the correct installation method. The most important principle is to keep the distance between the microphone and the receiver as short as possible.
2. Avoid placing the receiver next to a computer or other equipment that generates RF signals.
3. Avoid placing the receiver at the lowest level of the equipment rack, unless the antenna is Installed at a distance.
4. The receiver system can meet the requirements of 200 wireless microphones to be used at the same time without interference. However, professionals are required to debug different channels.
5. When multiple sets of wireless systems are used at the same time, please pay attention to the adjustment of “sq” position of the receiver. The lower the sensitivity is, the shorter the receiving distance is, but the stronger the anti-interference ability is. When the transmitter is close, it is better to switch to the low-power transmitting state to save points and reduce mutual interference.

Faults and Solutions

Troubleshooting the following table lists some common faults and solutions; if you can’t remove the fault, please contact your dealer.

No sound; (status: RF display of receiver is not on)

|

Check whether the power switch of transmitter and receiver is in “on” position.

Check whether the positive and negative polarity of the battery is disordered.

Check the antenna connection of the receiver. Ensure that there are no obstacles between the antenna and the transmitter.

No sound; (status: RF display of receiver is normal, AF display is normal)| Check that the volume knob of the receiver is at the minimum position.

Check the connection between the volume of the receiver and the loudspeaker.

No sound; (status: RF display of receiver is normal, AF display is abnormal)|

Check that the receiver is powered on. Switch the microphone of the transmitter if necessary.

When the transmitter is connected, the received signal has noise or external noise interference.

| Check that the battery is firmly installed. Eliminate nearby RF interference sources.

If using a guitar or other instrument, check the connection.

Both transmitters may use the same frequency to find and turn off one of them.

The signal may be too weak, readjust the position of the antenna to be as close as possible to the transmitter.

Change other channels.

There is noise in the receiver after the transmitter is turned off.

|

Adjust the receiving sensitivity adjustment button of the receiver; sq knob.

Eliminate RF noise sources.

Readjust the position of the receiver or antenna.

The sound of the transmitter is lost occasionally during the movement of the venue.

|

Adjust the receiving sensitivity adjustment button of the receiver; sq knob.

Re place the receiver and conduct the “walk field” test to observe the RF display.

If you find that there is a sound loss, mark the point and avoid going there during the performance.

Unable to turn on transmitter| Replace the transmitter battery.
