Upgrade biss-c impossible

I wanted to do a new installation test of the biss-c … Well, I can not disassemble my encoder 10000ppr.

At some point it must be removed with an M5 screw. Well, impossible to redo the manipulation, it does not want to be undone and I do not want to screw up

Perhaps the instructions here will help?

It is not unheard of , send it back for check and replacement.

I returned the product biss-c to simracingbay
