Any quick easy ways to get into program mode on these? I'm faced with a takeover of one. An existing cusotmer just bought a business that has one of these and he wants me to get it working or change it out for him.
Not much on the system, so I really don't have any problem with ripping it out and replacing it with a new system. I'll need to add some devices to bring it up to his standards anyway. Still if I can save us both a couple bucks.
