Ok, that could be possible. So far as I know there is a jumper on the Front
Panel PCB where one ca disable the LTC signal. I had an KDF-11 previously

Hmm.. most programs display something like "SW=000000 New Value=?", the
ZKDJB2.BIC does not, but it is described this way in the manual..
Thanks anyway, I'll check this..
