Canon MV830i viewfinder cleaning

Hi folks

just wondering if anyone out there with an 800 series Canon camera has worked out how to take apart the viewfinder to clean inside it.

The camera's only a few weeks old and already there is specs of dirt inside the viewfinder!!!!

I used to have this problem with my old 8mm canon camcorder but it was easy to take apart and clean.

any thought anyone with a Canon 800 series.

Cheers

Anyone
