cord from the wall outlet before you perform any main-
tenance on the projector.
Cleaning the projector and the ventilation
grille
Use a soft cloth to clean the projector and the ventila-

a soft cloth dampened with a diluted mild detergent,
and then wipe them with a dry cloth.

contact with the projector.
