The Hollyland Lark M2 microphones pair automatically when removed from their charging case. For manual pairing, you can turn off the microphone, press the yellow button for about 7 to 8 seconds to enter pairing mode, and then connect it to the receiver. The Lark M2 system does not use Bluetooth; instead, it connects wirelessly between the transmitter and receiver. It can be connected to a computer via USB-C for audio output.
