    Medium Flashing Mode(2) Short press S1 less than 1second The refresh frequency is general; 
    Slow Flashing Mode(1) Short press S1 less than 1second The refresh frequency is slow; 
    High Sensitivity Mode(H) Long press S1 more than 2second It can detect weaker audio signals; 
    Medium Sensitivity Mode(B) Long press S1 more than 2second It can detect general audio signals; 
    Low Sensitivity Mode(L) Long press S1 more than 2second It can filter more interference audio signals; 
     
    Using attention: 
    1. Please make sure all the components in the right direction and right place. 
    2. Please check whether pseudo/float welding. This is very important. 
    3. The soldering iron can't touch the components for a long time, otherwise, the components will be damaged because of the high temperature. 
    4. It is recommended to use a stable power supply, otherwise, it may interfere with the audio signal output.
