Help with new Vista 20

[Injun Ear]

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 do
4112, 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.

Thanks

4112 + 8 + 02 + new code
or
1234 + 8 + 02 + new code

The keypad will beep once when code change is successful. Try not to
hesitate when pressing the keys, Ademco panels don't like that.

You have to use the Installer Code to add the Master Code, then use the
Master to add other codes.
