The Conex 3300 models already have a Talk Back switch on ot that will turn it off which is disableing it already!! But for some reason you have to take it out then D80 is the number of the Diode inside the radio that controls Talk Back if you cut it or remove it your talk back will be gone!! Please take care in doing so because if you cut the wrong one you could destroy the radio!! And make sure the power is diconnected!!!

If their isn't a switch you will have to go into it and disconnect it. I would recommend having a professional do this. It is very miticulous.
