Help with ADT Security Manager 3000

Hi all,

Moved into a pre-owned home outfitted with an ADT security system. Previous owner did not use the alarm system and doesn't know the master code. ADT won't give me instructions on how to reset the master code without signing up for service. The system is currently flashing FC, 09, and 18 (I believe referring to zones) and is NOT READY.

I found previous threads on this forum that provided instructions on how to reset the master code - from the READY prompt. I need to clear the codes before trying it out. However, I do see the security implications of making public the method to reset a master code of a home alarm system.

Anyone have any comments or suggestions on how to get the system to a READY prompt and/or reset the master code?
