[1000mp] SSb nor setting

[Jeff - N3YEA]

I recently snagged a pair of Yaesu 2.0 kHz filters for my MarkV,
unfortunately they did not come with the
instructions. I got them installed and activated FB. 
My question is whether I need to change the    5-0 SSb nor    setting to
something other than OFF ?

Thanks
