Freezing up, and not storing cues, or looks, sounds like, and I'm guessing here < just want to qualify that first> it could be a battery issue. I would check the wiring diagram and see if there is a battery listed on the tech sheets. on many of the older memory systems a small lithium was used to retain volatile memory when the
unit turned off or unplugged. Most of those systems can crash quite badly when the battery runs out < I'll tell the story of the Panache I was running sometime> Be certain to reads specs and contact the manufacturer prior to servicing however. Many of these systems require you to "drain" a cmos chip prior to replacing the battery, it resets the BIOS flag that is the root of the freezeup in the first place. There area bunch of good guys out there at
EDI.
call them.
