Steve Kroop at Flytec USA reports that there is a fix for the low volume at 100%
for the Connect 1. He needs to drill a few holes. I'll send mine in for him to
do so.

The foil with the pinholes is covering a hole in the plastic
underneath, so you just need to drill a hole in the foil. Of course you need to
dismantle the vario before you do that. My vario is just as loud as my old
Flytec 4005 now.
