Precautions with regard to safety WARNING If you notice smoke, strange smells or noise coming from the projector, disconnect the power cord plug from the wall outlet. B Do not continue to use the projector in such cases, otherwise fire or electric shocks could result. B Check that no more smoke is coming out, and then contact an Authorized Service Center for repairs. B Do not attempt to repair the projector yourself, as this can be dangerous.
ENGLISH-7 Preparation B If the power cord is used while damaged, electric shocks, short-circuits or fire may result. B Ask an Authorized Service Center to carry out any repairs to the power cord that might be necessary. Do not handle the power cord plug with wet hands. B Failure to observe this may result in electric shocks. Insert the power cord plug securely into the wall outlet. B If the plug is not inserted correctly, electric shocks or overheating could result.
Do not look into the lens while the projector is being used. B Strong light is emitted from the projector’s lens. If you look directly into this light, it can hurt and damage your eyes. B Be especially careful not to let young children look into the lens. In addition, disconnect the power cord when you are away from the projector. Do not place your hands or other objects close to the air outlet port. B Heated air comes out of the air outlet port.
ENGLISH-9 Preparation Do not short-circuit, heat or disassemble the batteries or place them into water or fire. B Failure to observe this may cause the batteries to overheat, leak, explode or catch fire, and burns or other injury may result. When inserting the batteries, make sure the polarities (+ and -) are correct. B If the batteries are inserted incorrectly, they may explode or leak, and fire, injury or contamination of the battery compartment and surrounding area may result.
NOTICE: B This product has a High Intensity Discharge (HID) lamp that contains a small amount of mercury. It also contains lead in some components. Disposal of these materials may be regulated in your community due to environmental considerations. For disposal or recycling information please contact your local authorities, or the Electronics Industries Alliance: Accessories Check that all of the accessories shown below have been included with your projector.
Caution when moving the projector Be sure to attach the lens cover before moving the projector. The projection lens is extremely susceptible to vibration and shocks. When moving the projector, use the accessory carrying bag. When placing the projector inside the carrying bag, position it so that the lens is facing upward. Do not put anything else in the bag other than the projector and the cables. Cautions regarding setting-up Avoid setting up in places which are subject to vibration or shocks.
Notes on use In order to get the best picture quality Draw curtains or blinds over any windows and turn off any lights near the screen to prevent outside light or light from indoor lamps from shining onto the screen. Do not touch the surfaces of the lens with your bare hands. If the surface of the lens becomes dirty from fingerprints or anything else, this will be magnified and projected onto the screen. Moreover, when not using the projector, retract the lens and then cover it with the lens cover.

NOTES IMPORTANTES CONCERNANT LA SECURITE AVERTISSEMENT: POUR REDUIRE LES RISQUES DE FEU OU DE CHOC ÉLECTRIQUE, NE PAS EXPOSER CE PRODUIT À L’EAU OU À L’HUMIDITÉ Alimentation: Ce projecteur LCD est conçu pour fonctionner sur secteur de 100 V - 240 V, 50 Hz/60 Hz seulement. ATTENTION: Le cordon d’alimentation secteur fourni avec le projecteur peut être utilisé uniquement pour une alimentation électrique de 125 V, 7 A maximum.
AVERTISSEMENT: B Ne peut être utilisé dans une salle d’ordinateurs telle que définie dans la norme ANSI/NFPA 75 Standard for Protection of Electronic Computer/Data Processing Equipment. B Pour l’équipement branché en permanence, un dispositif de disconnexion d’accès facile doit être incorporé dans le câble d’installation du bâtiment; B Pour l’équipement branchable, une prise secteur d’accès facile doit être installée près de l’équipement.
FRANÇAIS-69 Others B Pour toute inspection, réglage ou réparation, s’adresser à un centre technique agréé. Nettoyer la fiche du cordon d’alimentation régulièrement afin d’éviter toute accumulation de poussière. B Si de la poussière s’accumule sur la fiche du cordon d’alimentation, l’humidité peut endommager l’isolant et entraîner un incendie. Débrancher la fiche du cordon d’alimentation de la prise de courant et l’essuyer avec un tissu sec.
Garder les piles hors de portée des enfants. B Si les piles sont ingérées, il y aura risque de décès par étouffement. En cas d’ingestion des piles, consulter immédiatement un médecin. Veiller à ce que les bornes + et - des piles n’entrent pas en contact avec des objets métalliques tels que colliers ou épingles à cheveux. B Sinon, les piles risquent de fuir, de surchauffer, d’exploser ou de prendre feu. B Ranger les piles dans un sac en plastique, et ne pas les ranger à proximité d’objets métalliques.
FRANÇAIS-71 Others B Ne pas installer le projecteur dans des endroits étroits, mal ventilés tels que des placards ou des étagères. B Ne pas placer le projecteur sur des tissus ou du papier, ces matériaux peuvent être aspirés dans l’orifice d’entrée d’air. Ne pas installer le projecteur dans des endroits humides ou poussiéreux ou dans des endroits où le projecteur peut entrer en contact avec de la fumée ou la vapeur.
B Ce projecteur continue de consommer environ 4 W de courant, même lorsque l’alimentation électrique est coupée. Débrancher la fiche du cordon d’alimentation de la prise de courant comme mesure de sécurité avant d’effectuer tout nettoyage. B Sinon cela peut causer des chocs électriques. Demander à un centre technique agréé de nettoyer l’intérieur du projecteur au moins une fois par an.
Si le projecteur est installé au plafond, demander à un technicien qualifié de faire tous les travaux d’installation. Il faut acheter le kit d’installation séparé (numéro de modèle: ET-PKB30). En outre, tous les travaux d’installation doivent être exécutés uniquement par un technicien qualifié. Si l’on utilise ce projecteur à un endroit élevé (au-dessus de 1 400 m), régler le “VENTILATEUR” sur “FORT” (se référer à la page 45). Sinon, des anomalies pourront se produire.
