Bague de mise au point d’objectif
Avant d’appeler l’assistance technique
1)La lentille est-elle dans l’objectif ? (Référez-vous plus haut.)
2)La distance de projection est-elle adaptée pour cet objectif ? (Vérifiez la distance de projection.)
Precautions de manipulation:
•Ne démontez pas cet appareil.
•Veuillez vous adresser à votre revendeur agréé pour toutes les vérifications et opérations d’entretien.
Entretien:
•L’installation des nouveaux objectifs de rechange devrait être effectuée dans un environnement sans poussière pour éviter que des particules de poussière entrent dans la voie d’accès optique entre l’objectif et le projecteur.
•Lorsque vous nettoyez la lentille, utilisez une bombe d’air comprimé et un papier spécialement prévus pour le nettoyage des lunettes et des lentilles photographiques.
•Evitez de nettoyer avec un tissu abrasif ou tout autre matériel rugueux qui pourraient endommager la surface de la lentille.
•N’utilisez pas les décapants ou les pulvérisateurs liquides d’aérosol. Utilisez un tissu humide pour le nettoyage.
