Locked Out by Vendor

[scantrell113@xxxxxxxxx]

After many many years of sticking with the monitoring service offered
by my initial home alarm installer, due to constant compounding price
increases I decided to get service from another company.  I come to
find that my trusted provider has locked the new monitoring company
out the controller.  When they sold me the system, they sat at my
kitchen table and told me that I was under no obligation to continue
with their service and that I owned the equipment.  What they did not
disclose was on small line in a wordy and lengthy contract that
stipulates that they own the communicator.  We=92ve probably all signed
documents relying on anticipated fair business practices without
parsing words (=91I did not have sexual relations with that woman=92).
Two questions, is this common practice and is there a hardware reset
on a Radionics 4112?
