| 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.
