ADT Safewatch pro 300: How to enter programming mode

I used to enter programming mode using 6321 + 800. Starting this morning after I tested by system, I hear a long beep as oppose to entering a programming mode when I do 6321 + 800. I am doing this when the system is disarmed.

Can someone help me here with below questions:
-- What does a long beep mean when I enter 6321 + 800?
-- And How do I reenter programming mode?

Thanks in advance..

It means that either the installer code got changed, or the last time you went into programming, you exited with something other than *99.

You should still be able to get into programming by powering down (AC and Battery) and pressing * + # within 50 seconds of restoring AC power.
