Basic Operating Instructions
Microphone
- Unscrew the battery compartment (5), and insert a 18650 lithium battery (3.7V), paying attention that the positive and negative polarity cannot be reversed.
- Short press the microphone power switch (3) to turn on mic, the display (2) will turns bright, showing the working frequency, channel and battery real-time power; long press the switch to turn off mic.

Receiver
- Open the battery compartment 【7】, insert a lithium battery, and note that the positive and negative polarities cannot be reversed.
- Turn the receiver switch 【2】 key to the "ON" position, when the power indicator 【3】 turns green, the receiver will work normally.
- Receiver signal indicator 【5】 turns green indicate the receiver has successfully connected to the microphone of the CHA channel, turns green indicates the microphone of the CHB channel has been successfully connected, turns green at the same time indicates the receiver has been connected to two microphones, they can be used at the same time.
- When the receiver's battery under low power status, the green light 【3】 will slightly dim; When charging, the power indicator light 【3】 will turns and keep red, after fully charged, the red light will turn off, 【3】 not light.
Common Troubleshooting
| Problem | Solution |
|---|---|
| The microphone cannot be turned on | Please replace a new 18650 (3.7V) lithium batteries and check the positive and negative directions of the batteries to make sure they are in the correct direction. |
| The microphone is automatically turned off | Please replace a new 18650 (3.7V) lithium batteries |
| The receiver cannot be turned on | Please charge the receiver and check the positive and negative direction of the battery. If the problem cannot be solved, please replace a new 18650 (3.7V) lithium battery |
| The receiver cannot be charged | Please below methods:
|
| The receiver and microphone have sufficient power, but the microphone has no sound, or only one microphone has sound | Please check the channels of the two microphones from the microphone display, make sure that the two microphones are on the CHA and CHB channels respectively, the two microphones cannot be set on the same channel. |
| Microphone whistling | The microphone is too close to the speaker or the volume is adjusted too high, please turn down the volume of speaker or keep away from speaker |
