Undoubetdly it was a factory setup IR code. Recently, in the process of getting all the
working EFC's I could find for my new RCA vcr,
I found a code for "DISPLAY" (on screen info),
except it worked and looked a little differently
than the remote's DISPLAY function (although the
remote's DISPLAY function was on a different code). When you hit this factory code, it had all
the regular DISPLAY information, but in the middle of the screen it says "Batteries are low on the remote". So I went along with the joke and checked
my remote's batteries to see if this was true.
It was a lying DISPLAY function. Still, interesting... never know what you might find
fooling around with these codes. You could
also hit something harmful to your equipment, apparently.
