beginner questions...high pitch tone on BFD

[Mattlock]

Does anyone know why my BFD emits a high pitch tone when I startup my amp? It only does it on group 5 filters. (I have both 4 and 5s programed with filters) Group 4 doesnt do it.

I am sure it is a simple reason...just learning the basics here

thanks
Matt

Are all the unused filters set to the OF mode?

What amp are you talking about?
