							Cleaning
Caution!
Switch off and disconnect the projector before cleaning.
1.When the cabinet is dusty, clean it by gently wiping with a
soft cloth.
2.A chamois leather slightly moistened with water is sufficient
for cleaning the housing.
3.Do not use cleaning agents as they may harm the housing.
Always keep the lens clean
1.When the lens is dirty or dusty, first blow the dust off and
then gently wipe with a soft brush or lens cleaning paper.
Never touch the lens with your fingers.
2.The lens is likely to become mouldy if left dirty.
Cleaning the dust filter
1.Press the Stand by On button to switch off the projector.
– The standby indicator lights up red.
2.Wait until the cooling fan has stopped (about 3 minutes and
disconnect the mains lead and all other cables.
3.Turn the projector over. Never place the projector on the side
where the connections are located!
4.Press tab A and lift up the cover.
5.Turn the cover upside down. The filter is located on the cover
underside.
6.Carefully remove the filter
from the cover.
7.While firmly holding the filter, gently remove any
accumulated dust with a vacuum cleaner.
8.Replace the filter.
Firmly press the filter edges 
in place.
Check if the filter is firmly
tightened by turning the
cover upside down.
9.Replace the cover.
Notes:
– We advise you to clean the filter every 100 hours.
– Operating the projector without filter or with a torn or damaged
filter may seriously damage the projector.
– When the filter is damaged replace it with a filter of the same type
(12 nc:  3122 434 01180).
– The projector power cannot be switched on again unless the filter
holder is installed correctly.
Maintenance of the trackball remote control
Your trackball on the remote control is very durable and will provide
years of use. It has a self-cleaning ball-cage that helps prevent dust
and lint built-up around the ball. If the screen cursor jumps or moves
abnormally, we recommend that you clean the trackball manually.
To clean your trackball
1.Turn the retainer ring counter-clockwise to remove the ball.
2.Wipe the ball with a clean, lint-free cloth.
3.Blow carefully into the ball cage to dislodge dust and lint.
4.Look for a built-up of dirt on the rubber rollers inside the ball 
cage. This build-up usually appears as a stripe running around the
middle of the roller.
5.If dirty, clean the rollers using a cotton swab moistened lightly
with isopropyl (rubbing) alcohol. After cleaning, make sure the
rollers are still centered in their channels.
6.Make sure that fluff from the swab is not left on the rollers.
7.Replace the ball and retainer ring.
