Re: Radionics D7212B1 Panel Help

["WYSIWYG" <nospam@xxxxxxx>]

Badenov,

Thanks for the information. I am in contact with Jim Rojas and were going to
give it a try.

I appreciate the detailed information on the lock-out mechanisms on these
boards. One of the problems I have is understanding what is "normal"
behavior and what is the result of losing the lithium battery. Can you give
more info on the lockouts and passwords that are used? I am currenly
decompling the EPROM program and I have located at least one password in RAM
along with the default "000000" in ROM. How many levels and types of
passwords are used in these things?

Thanks for all your help.

Bob
