1. Adjust the microphone frequency point, open the microphone and press and hold the up button until the SEL character appears, then adjust the frequency point to avoid the original serial frequency point, and then bring the microphone close to the speaker and wait for the frequency matching to be completed

2. Press the power button and the up button at the same time to identify the microphone ID to avoid subsequent mistakenly touching the frequency change or cross-frequency again

3. The fixed frequency microphone cannot be modulated, if there are other microphones nearby that use the same frequency point, you can adjust the distance or change the venue
