Today some car friends asked me to demonstrate my LI.
One of them had a palm and set my LI off. All of a sudden you hear warning beeps and then it went dead. We tried again but I heard no sound but saw the LED light flashing on my switch. I changed the jumper in my LI unit from "External Speaker" to "Internal Speaker" and sure enough the internal speaker worked fine.
Escort speaker wasn't even 6 months old and it's dead. What a POS.
