Hi<br />
<br />
It is very abnormal to hear a non stop squeaking from such a device, if it have a self diagnostic tool use it to see if it points out a problem, in any case I suggest you to distrust it and bring it to a service for repair, if it is still in warranty period just do not think a minute more about it, bring it to service now.<br />

Unplugged everything.....squeaking continued but I noticed on the front panel a button that said &quot;Press and hold to mute.&quot; I muted it.....and squeaking has stopped. Surely this hasn't fixed the problem BUT.....unit is long out of warranty and for now the noise has subsided.

I wouldn't use that unit at all if it's in some kind of fault indication condition.<br />
