13.1 Projector lenses
General guidelines for cleaning projector lenses
Blow off dust with clean compressed air (or pressurized air cans) .
Use lens cleaner and a clean lens cleaning cloth to remove the dust and contamination.
Wipe in broad strokes, in one direction only.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
Use a dry clean lens cleaning cloth to remove left liquid or stripes. Polish with small circles.
If there are still fi ngerprints on the surface, repeat with lens cleaner and a clean lens cleaning cloth, then polish again with a dry cloth.
If smears occur when cleaning lenses, replace the cloth. Smears are the fi rst indication of a dirty cloth.

General info regarding Air intake and fi lters.
The product is shipped default without any fi lters and by avoiding fi lters, the ventilation system operates for longer periods between
maintenance, since no clogging of fi lters means more air is allowed through the system, resulting in lower operating temperatures
over time. The air intake are just protected by a mesh. This mesh has to be vacuum cleaned occasionally when needed. No speci fi c
interval for this operation, but to be performed when needed.
For more demanding surrounds both smoke and dust fi lters can be applied externally to the system to avoid internal fouling.
General guidelines for cleaning projector fi lters (external)
Remove the fi lter from the projector then use a vacuum to remove excess dust from the fi lter. Do not wet or soak the fi lter.
Cleaning of the projector fi lter should be done in a separate room to avoid dust contamination.
