C-4 Description of Self Test Items
Analysis to test failure
If the test result appears NaN, it indicates the microphone is not plugged in well or the circuit is not
in the place.
The microphone’s interface goes wrong if the test result appears FAIL.
Suggestion to failure test
Ensure the microphone works well first. The sound waves appear on the screen if the sound
arrives at the microphone The interface does not work if the sound waves do not appear on the
screen. It is recommended to replace the PC carrier board.
