I have a Leader 3220 that worked well for a while but now seems to perpetually be out of lock.
I have diagrams but they aren't all that helpful. What would help would be an extender board but I don't know where to get one.
Does anyone have one of these or know anything about them? A source of boards might help so that by substitution I could narrow my sphere of investigation.
This unit is composed of an internal rack with a number of plug-in modules, and I suspect one of the modules needs adjustment or repair.
