[Leica] Snapshot Profile mode

[bob catchpole]

Hello list,
I've just started using a digital Leica, the M-E. My questions are about the Snapshot Profile mode, which I'd personally like to have as little to do with as possible!
1) In the Snapshot Profile mode does the camera only shoot JPEGs?
2) Is there a risk of accidentally switching on the Snapshot Profile mode?
3) Is there a way of making sure the Snapshot Profile mode can't be switched on accidentally? Can it be permanently disabled?
Thanks,Bob
