Switch off and disconnect the projector before cleaning.
1 Press the Standby button twice to switch off the projector.
– The Standby indicator starts blinking orange.
2 Wait until the cooling fan has stopped (about 3 minutes after the projector has been put in
Standby) and disconnect the mains lead and all other cables.
Cleaning the cabinet
• When the cabinet is dusty, clean it by gently wiping with a soft cloth.
• A chamois leather slightly moistened with water is sufficient for cleaning the housing.
• Do not use cleaning agents as they may harm the housing.
Cleaning the lens
• 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.
– The lens is likely to become mouldy if left dirty.
Cleaning the dust filter
Make sure to clean the dust filter regularly.
1 Switch off the projector and wait until the cooling fan has stopped before disconnecting the
projector.
2 Turn the projector over. Never place the projector on the side where the connections are
located!
3 Press tab A and remove filter holder B from the projector.
4 Press clamp C, open the holder and remove the filter.
5 While firmly holding the filter, gently remove any accumulated dust, from the dusty side, with
a vacuum cleaner.
6 Press clamp C, put the filter back in place and release clamp C. Firmly press the filter edges
in place.
7 Close the filter holder.
8 Press tab A and insert the filter B into the projector.
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 0157 0).
The projector power cannot be switched on again unless the filter holder is installed correctly.
