FAQs
For the GEM-P816, GEM-P1632 or GEM-P1664 control panels, how can I enter Dealer Program Mode (and thus make programming changes) without possessing the control panel Dealer or Master Security Code?
The ONLY solution is to possess a working Dealer or Master Security Code to allow entry into Dealer Program Mode. This Code will allow you to make all needed changes to the control panel programming.
