That is what I was told by Outlaw Support when I called for my 755(three years ago) and I trust that the symptom on my 7700 has the same root cause.

If you want a more definitive, 'official' answer, give the outlaws a call (or drop them an email). It'll cost you nothing and you'll have a documented answer straight from the horses mouth.
