Any chance you can dig up that manual? Some pics of it would be very helpful as I troubleshoot our Newtec that is faulting.When I first got my 34, the Newtec control would start intermittant beeping every time we used it, frustrated mute button pressing was part of the routine until I found the manual and realized it was a sniffer fault, traced the wires and found a bad connection. Now I use the butane lighter test every time I use it just in case.
