Bc2000 (for the BCF2000 & BCR2000)

Hi,
first post, just got my BCR2000 yesterday.

Does updating the firmware erase any user made presets?

I installed the Mopho presets (thanks for those!) i found here, and then realised that maybe i should have updated the firmware first.
Sorry if this has been asked before, tried a search but didn't find any info.
br,
Tode
