Airtronics MX-3 ERR3
Has anyone ever gotten the message "ERR3" on the display of their MX-3 with a beeping noise when it's turned on? This keeps happening to me! It goes away if I hit an arrow key or the +/- signs. I set all the values back to the default and popped the batteries out.. no go. I also the checked Airtronics website and manual, but I couldn't find anything.. any ideas?
