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.
