Mode setting:
Mode Set Method Remarks:
Factory Testing Mode Press button S1 before Power on It is used to detect all LED whether can be ON;
Fast Flashing Mode(3) Short press S1 less than 1second The refresh frequency is very fast;
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.
