[NHRC-user] Lost control code

[Arnold Harding]

A while back I moved.  Now I would like to change some parameters in 
my NHRC-7, but I can't find the control codes (who knows which box). 
Is my only choice to reset the entire controller, or can I just change 
the control code with the jumper?
Resetting the entire controller to defaults might not be all that bad 
since I'd create a new list, but I thought I'd try to keep life simple 
for the moment.
Suggestions?
