Romeo,

First of all, I can't answer to the call of "wizard." Folks on my
field call me by other "terms of endearment."

But that won't prevent me from pitching in and trying to answer. Your
issue is why I try to keep an appropriately-sized cardboard box
handy. So I can ship my 302 to Cambridge. I don't know what it is,
but I would suspect your 302 will need a check-up at Cambridge. I've
had the same problem before.

I've lost count, but my 302 has been back to Cambridge at least twice,
maybe three times in the four or so years (maybe longer?) that I've
had it. And, it's time to go back again. Now, the audio function of
the vario seems "off." And, it's time for a recalibration (I'm gonna
get 500 km this coming year, I just know it! ;-)
