The sense of abbreviations

Hi all,

I'm wondering what's the sense of the abbreviations on the Moonbase
consoles? For example, there are some switches with lights above and
beyond and the following abbreviations: RS, REC, AT, UL, G and RE.
Well, REC could mean "record" or "recording" respectively. Does
anyone knows if these abbreviations have any meanings?

To make things easier I'll send the frame capture, too.

Christian
