[time-nuts] True TimeGPS receiver display contrast adjustment

[Raimond Melkers L-3 Titan]

I have a TrueTime MARK V Time and Frequency GPS Receiver, and I'd like to
adjust the contrast on the  small front panel display. I've looked thru my
manuals, and did the Google thing, and no luck, I've done it in the past,
but sadly I was younger, and thought I wouldn't need to write down that
undocumented trick!!

Any suggestions?
