Hi,

My guess is that the S-NAV needs repair. *Gary Kammerer at ClearNav can
probably fix it for you. *You can reach him through their web site atwww.clearnav.net.

You can download the S-NAV and GPS-NAV manuals atwww.cambridge-aero.com.

You should also check out the free training/demo tools for L-NAV and GPS-NAV
on my web site. *The L-NAV demo covers most of the functionality of the
S-NAV - but not the tasks - which would be done in the GPS-NAV.http://www..cumulus-soaring.com/cai_downloads.htm

So I bought a glider with an S-NAV&GPS-NAV not long ago, and I don't
really know how to use either. However, when I start up the S-NAV, the
unit thinks I am at 28300ft, when actual elevation is 434ft. Obviously,
it won't let me adjust the altimeter enough to get the right elevation.
On the startup "altimeter" screen, I set the pressure setting to the
same as my regular altimeter (29.92 or whatever), but the altitude
readout is still way off. Anyone run into this? Is it broken, or am I
missing a setting somewhere?

Another option, leave it as is and brag to your friends on a day with
only 6000ft cloud bases and no wind you managed to climb 28,300ft.
Check out Craig's R'.s theory. I'm not familiar with the the SNAV
myself, but the possibility that 28,300ft is the altitude needed to
glide to a preselected task seems plausable. Where is your glider
from; if the previous owner still had it set to a location in that
region, is 28,300ft needed to reach that location from where it
currently is???
