LNav "meter" problem

[Kurt[_3_]]

I have a LNav / meter that has worked fine in the past. Sunday the meter pegged out at 10 knots and stayed there. I cycled the LNav a few times and it kept doing the same thing. Does anyone have experience with this, and if so, what was the fix? The LNav itself seems to be fine.

Thanks

Kurt

Kurt, can you zero the meter using the calibration page? If not, I think your LNAV needs to visit Gary Kammerer. But the instrument is so old that parts if needed might be a problem.

We had a similar problem with our Club's Discus and LNav. Gary fixed it--don't know what he did!

Thanks. I will look at the calibration page, and if that does not fix it, I will send it in for repair.

Its always worth replacing the internal lithium button battery and then
reseting internal parameters back to factory default.(Page 20 of the
version 5.8 manual, followed by re-entering your polars etc)

Apparently when the battery gets low, some of the stored internal parameter
values in battery backed up RAM can get corrupted and "strange things" can
start to happen.
Replacing the battery and doing this factory reset has fixed my LNAV in the
past.
(This was a tip given to me by the Dickie Feakes the UK service agent.)
