The installation environment has poor sound insulation performance or too much noise, and the distance between the main unit and the auxiliary unit should be increased or the volume should be turned down.
2. Silent:
If the 220V power supply is not properly plugged in or loosened, insert the 12V transformer into the main unit (power supply) jack.
The volume knob is not turned up: you can turn the volume knob clockwise to increase the sound.
3. Interruption:
The speaker is too far away from the microphone and should be closer (less than 20cm is ideal);
When one party is talking, the other party will be resisted if they rush to talk;
The environment noise is too strong, you can turn down the corresponding speaker volume or ask the speaker to get closer to the microphone.
