Press “Yes” if the audio is clear and sounds like a pure sine wave.
The LCD will display a new message: NEW MESSAGE = “PROTECT MODE 4” | “SPEAKER IS OKAY” | “EXIT”
Press “EXIT” and the speaker will go back to the “Home” screen and resume normal operation.
Press “No” if the audio has distortion or is NOT CLEAR.
The LCD will display a new message: NEW MESSAGE = “PROTECT MODE 4” | “PLEASE CONTACT A QSC SERVICE CENTER”
This indicates that there is already damage on the low frequency driver and that the speaker will need to be sent to a QSC Authorized Service Center for further inspection.
If “NO” was pressed accidentally and the tone was in fact clear, power cycle the speaker and the PROTECT MODE 4 message will start over again. Proceed through the test again to confirm that the tone is clear.
