    TRIG TT21 query

    Friend has a KWIK which came with a Trig TT 21 Txpdr installed. It's been a while since I've flown any Ifr using modes A and C, can anyone suggest the meanings of Two of the functions please, I've looked at the Trig site, but simplities such as Panel description were not forthcoming ( ! )

    1) There is a button marked 'FN' 2) on the Mode knob, what does the abbreviation GND refer to ? I don't recall these on old transponders which I used in the 1980s

    Thanks in anticipation.

    Phil.

    I hate doing google links as answers to questions, but in this case it's probably best to download and read the user manual and you can do it from this link:
