OK, I have put resistors on all the zones so I can program this thing on the bench. I can get into the programming mode, I can arm and disarm it with the installer code or the default 1234 code. But HOW can I change the user code? I tried entering 4112 + 8 + 02 and it doesn't do anything. I tried 1234, 8, 02 and it still doesn't . But If I do4112, 8, 00, I get into programming mode. Do I need to have the battery connected before it will work? I'm running with no battery right now to test this thing. I would like to have it pretty much programmed before I start installing it.
