This function is used to check that the convergence microphone works and that the connection between radio and convergence is intact. For a positive result a beep will be heard from the convergence microphone.
In case of a negative result, proceed as follows:
Begin by restarting the system using the "Restart convergence control unit" function. Then retest using "Test the audio system". If the result is still negative, check as follows:
If you can hear a beep from the radio: The problem is in the microphone, which may either be faulty or incorrectly connected.
If you cannot hear a beep from the radio: Check the connections (cables, contacts, etc.) between convergence and the radio.
Test conditions:
Ignition on
Procedure:
Start the function.
Follow the instructions in the program.
The function is complete.
