Batboard

I just upgraded my 3920 to ver 3.2.0. This release includes a frequency list. I am looking for any information on what the list is for and how to use it. Aeroflex does not have an updated manual on their website, issue 9 being the latest which was published months before the 3.2.0 upgrade.

Two questions,
1) Is this simply just for reference?
2) What is the "Fill Rec Freq" button do? I didn't see it do anything.
