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 components in 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.
