Writing from South Africa my Houston Tracker llsc model Positioner is in parental lock out mode.I do not have a manual and enquire whether any one can advise me how to remove this mode.Even better the actual manual will be a great help.
The only thing I can remember about the old Tracker II positioner is (I believe) that if you hold the reset button and press the power button, it will reset the memory and you have to set the limits. I'm going by memory so I might be wrong. I haven't touched one of those since probably the late 80's or early 90's. I have no idea where you could find a manual. I know a guy who used to be with Houston Tracker. I'll try to reach him and see if he remembers about the PL.
