HI, i have been using Panasonic switching system KX-T308 with 2
external lines and now i want to add a third line - the problem is that
the 83 exit is disabled. I tryed to change it according to the book -
dial '02' in the programing option  - but while the book says i will
get"CO CONNECTION", I get "CLASS 1" - and i can change it only to
"CLASS 2" or "CLASS 3" what make no difference! Anyway if any one knows
how to do it please let me know...
