instructions for cleaning Letus?

[dus10]

I have posted on here, after calling, leaving voicemails, and emailing those at Letus. I was wondering if anyone has instructions on how to take apart a Letus ECONOMY to clean it. I have something affecting my image, not sure where it is inside the unit, but it is there and I do not know how to remove it. Any help would be greatly appreciated.

For the Mini - so not sure if this will apply to the Economy - but (in clean room with minimal dust) loosen allens keys and slide the casing off. Blow air using rocket blower (not compressed air) on both sides of the focussing screen.

Probably best to wait for the manufacturer to confirm, as I'm not sure about the Economy's build though.
