Just bought an FC40 (FCC/CE question)

[Grey Area]

Reading the manual it says two beeps = FCC mode. I was expecting CE mode as I'm in the UK. Should I change it back?

Also: screws. Manual is not clear on what goes where. I have 14pcs M3x6.5, 5pcs M3x8.

I'm assuming the 6.5s are for the legs (8 required) (even though the manual says 6.0s). That leaves me 6pcs 6.5 and the 5pcs M3x8. What do I use for the FC40 camera bracket (2pcs) and the device holder (2pcs)?

Are the leftovers just spares?
