With my new glider, I got a box of extra equipment. Included was a
never-used Rico audio vario, still in the box, but without
documentation. It checks out good. But does anyone have any info on
these varios?

Specifically:

What size capacity bottle should be used with this?
What are the functions of the large and small dials? Trim?
What is the performance of this Rico? My glider has a nice Scheumann CVA averaging mechanical vario, but no audio. Is the Rico worth installing?

Use it, you'll like it while it works. If it's like every other piece
of Rico gear I've had my hands on (N 6 in this case, mix of club and
privately owned equipment), it won't be working for more than two
seasons (the point of which is to say "don't cut up a perfectly nice
panel to install this").
