That would be user manual for FX505 series, which is pretty minimalistic.
It says it has a fan mode switch key and that's it. Following up on your

overboost and silent there.

Appreciate your comments! Will definitely implement them. I'm going to post
the v3 patch series approximately middle of next week.
