When thermalling at 60-65kts the vario tone was modulated by what I
can only describe as a cavalry charge bugle call. Yes, this is
probably the slow alarm but it should not have been sounding as the
slow alarm speed was set to 40kts.

It took me most of the practice day flight to figure out what was
going on. I don't know if the the problem is fixed in the current
firmware. At that time I was one version out of date.

Andy,

When you say that the slow alarm was interfering with the vario, do you
mean that it tended to make the vario sound intermittent? If so, that
IS the slow alarm. The slow alarm is not a siren as you might think,
but it simply interrupts the vario audio so one might easily think that
they have a problem with their vario audio until they find out it's a
"feature not a bug".

Same thing happened to me by the way.
