I was on holidays until yesterday. That's why I did not answer so far.

I'd agree to Florians diagnosis. Only in the worst case it could be the
CEM3340. But I think it's a faulty potentiometer or trimming potentiometer
or rotary switch. It's impossible to estimate the repair charges in advance
because all depends upon the required working time and spare parts.

You may send in the module to our address for repair (see ABOUT US on our
website). In this case please follow the repair notes on the FAQ page of our
website (as the procedure depends upon your home country and the purchase
date). The A-111-1 modules are serviced by Matthias Marass
( keyboards@... ).

Best wishes
