Having some trouble with my mazak qt15, wondering if anyone has come across this alarm. the control is a t2 and won't allow me to insert any more lines of program or get past the initial first line of program. i know the memory isnt full as i empted half of it when the alarm first showed up. any help would be much appreciated. (dont know if this is relevant but it only started to do this after replacing the nmi battery) . cheers
