Procédure de nettoyage du miroir
asphérique et de la lentille
Si le miroir asphérique ou la lentille de projection sont
poussiéreux ou tachés, veuillez les nettoyer en suivant la pro-
cédure suivante :
1. Éteignez le projecteur et laissez le refroidir pendant quelques
minutes.
2. Débranchez la prise d’alimentation électrique.
3. enlevez la poussière avec une soufette que vous pouvez trouver
chez les revendeurs de matériel photographique. Essuyer le
miroir et la lentille délicatement avec le chiffon de nettoyage.
ATTENTION:
Ne pas essuyer le miroir, s’il ya de la poussière sur lui, veuillez s’il vous
plaît enlever la poussière avec une soufette en premier.
Toujours essuyer le miroir ou la lentille avec le chiffon de nettoyage.
S’il vous plaît ne pas essuyer de façon trop appuyée le miroir ou la lentille
car cela peut causer de graves dommages sur la surface du miroir ou de la
lentille.
Le nettoyage risque de rayer le miroir ou la lentille. Les performances op-
tiques du projecteur sera donc affectée si le miroir ou la lentille sont rayés.
L’impact sur les performances optiques dépendra de la taille des rayures.
Ne pas utiliser de nettoyants liquides ou des produits chimiques pour le
nettoyage avec le chiffon, car cela peut causer de graves dommages sur la
surface du miroir ou de la lentille.
