5. FAILURE INDICATION AND SAFETY

The microprocessor is able to signal three different kinds of failure by ﬂashing the “Limiter” red LED on the ampliﬁer panel before the lighting up

of the “Power status” green LED�

The three types of failure are:

- WARNING: a non severe error or auto-ripristinate malfunction is detected and the performance of the speaker is not limited�

- LIMITATIONS: an error is detected and the performance of the speaker is limited (the sound level is reduced by 3 dB)� This does not affect the

operation of the speaker since it continues to operate� However, it is necessary to call the service centre to solve the issue�

- FAILURE: a severe malfunction is detected� The speaker switches to “mute”�

FLASHING INDICATION:

1 or 2 : Warning

3 or 4 : Limitation

5 to 8 :Failure� In case of failure, the “Ready” green LED remains off�

Perform the checks listed below:

- check if the speaker is properly connected to the power supply

- make sure that the power supply is of correct voltage

- check that the ampliﬁer is not overheated

- disconnect the speaker from the mains power supply, wait for a few minutes and connect it again� If after these tests the red “LIMITER” LED is

still on, please contact an authorised service centre�
