[GreenKeys] Questions About an AN/TGC-14(V) and TT-318/UG + More

Wed Apr 15 14:21:48 EDT 2026

Fabiolah,

I haven't opened a Mite in years and don't remember exactly how it works 
and don't have one to look at here.  The pressure relief valve will work 
immediately. It may be that one of the latches is not released 
completely. If the cover and both latches feels loose, then it may just 
be the seal sticking some.
