AT897 and flat/roll off switch

Obviously a newbie question here, but ...

I just bought an AT897 and I see it has a flat/roll-off switch. Upper setting is slightly curved and the bottom setting is flat.

Can someone please explain what each setting is (I assume the flat icon is for the flat setting, but you never know) and what environment I would use each for?

Thanks alot in advance.

It's a bass rolloff, necessary in boomy areas. It starts at either 100 or 80 hz, I've forgotten which, and rolls off at eithe r10 or 12dB per octave after that, so it's a semi sharp slope at which it starts to cut off low freqs. Necessary in windy areas, necessary if you are needing to use a shotgun indoors.
