About this chapter
This chapter contains the lamp replacement procedure, which can be done by a trained operator. Next to that, some information
about air
fi lter replacement is available. The air fi lter replacement itself can only be performed by Barco quali fi ed service technicians,
since a ’hidden’ menu item is needed to reset the air fi lter runtime.
Maintenance procedures like lens cleaning, etc are also explained. These procedures can easily be performed by the operator or
owner of the projector.
Advanced service information
Advanced service information for quali fi ed service technicians (e.g. Service manual) can be found on https://my.barco.com/de-

How to clean the lens?
1. Blow off dust with clean compressed air (or pressurized air cans
2
) .
2. Clean with lens cleaner together with a clean lens cleaning cloth to remove the dust and contamination. Use big wipes in one
single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Use a dry lens cleaning cloth to remove left liquid or stripes. Polish with small circles.
4. If there are still fi ngerprints on the surface, wipe them off with lens cleaner together with a clean lens cleaning cloth. Polish again
with a dry one.
If smears occur when cleaning lenses, replace the cloth. Smears are the fi rst indication of a dirty cloth.
8.2 Cleaning the exterior of the projector
How to clean the exterior of the projector ?
1. Switch off the projector and unplug the power cord at the projector side.
2. Pressurized air cans are not efficient if there is too much dust on the surface, the pressure is too low
