Good point Paul but that was my first reaction too, and I did go
to the trouble of ensuring that the knob was not fouling the
panel. Can't believe such an obvious fault was not picked up in
QA, along with a series of others.

Hi Jim,

It would seem to me that the failure of the pushbutton to work
was caused by
a poor installation - which is easy to fix by removing and
re-attaching the
knob. It may not be fair to blame the manufacturer for that.

If no one plays with the settings

In practice, this is impossible. It only has one rotary knob
which services at least ten pages of functions - only one of
which is volume. The first time one turns on the glider power
the
vario will scream . . a punter will reach for the vario's
'volume' knob, give it a twist, no matter what page it is on,
etc, etc. To make it worse, the way to change pages is to press
the knob - and this function was faulty on the new unit that I
have used . . . Of course the 'double-click' to get back to the
'home' page failed as well . . .

Not a good device unless *all* pilots are prepared to learn how
to use it properly, which includes not 'fiddling' (and you get
a
good unit).
