Error "Prisim optosensor not found" in M5 AAS

Hi Mujeeb,

this one requires a Thermo certified specialist to check the prism motor drive and the prism arm assembly. Assuming that the optosensor cable is in place and works properly of course. To get to this assembly and check it you must remove a lot of other parts and this is the reason you have to call an expert. If you try to do it on your own, make sure you have a lot of space in the bench.

Good luck
