Maintenance65 Maintenance Care of the projector Your projector needs little maintenance. The only thing you need to do on a regular basis is to keep the lens clean. Never remove any parts of the projector except the lamp. Contact your dealer if other parts need replacing. Cleaning the Projector Mirror Remove the dust with a Bellows/Lens Blower readily available from camera shops to prevent scratching the mirror with subsequently wiped. Cleaning the lens Clean the lens whenever you notice dirt or dust on the surface. • Use a canister of compressed air to remove dust. • If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the lens surface. Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact with rubber or vinyl materials may result in damage to the projector surface and cabinet material. Cleaning the projector case Before you clean the case, turn the projector off using the proper shutdown procedure as described in Shutting down the projector on page 50 and unplug the power cord. • To remove dirt or dust, wipe the case with a soft, lint-free cloth. • To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH detergent. Then wipe the case. Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case. Storing the projector If you need to store the projector for an extended time, please follow the instructions below: • Make sure the temperature and humidity of the storage area are within the recommended range for the projector. Please refer to Specifications on page 76 or consult your dealer about the range. • Retract the adjuster feet. • Remove the battery from the remote control. • Pack the projector in its original packing or equivalent.
Maintenance 66 Transporting the projector It is recommended that you ship the projector with its original packing or equivalent. When you carry the projector yourself, please use the original box or a suitable soft carry case. Lamp information Getting to know the lamp hour When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows: See Setting Lamp mode as Economic or SmartEco below for more information on Economic mode. To obtain the lamp hour information: 1. Press MENU/EXIT and then press ◄/► until the SYSTEM SETUP: Advanced menu is highlighted. 2. Press ▼ to highlight Lamp Settings and press MODE/ENTER. The Lamp Settings page displays. 3. You will see the Equivalent lamp hour information displaying on the menu. 4. To leave the menu, press MENU/EXIT. You can also get the lamp hour information on the INFORMATION menu. Extending lamp life The projection lamp is a consumable item. To keep the lamp life as long as possible, you can do the following settings via the OSD menu. Setting Lamp mode as Economic or SmartEco Using Economic mode reduces system noise and power consumption by 15%. Using SmartEco mode reduces system noise and lamp power consumption by up to 30%. If the Economic or SmartEco mode is selected, the light output will be reduced and result in darker projected pictures. Setting the projector in Economic or SmartEco mode also extends the lamp operation life. To set Economic or SmartEco mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp mode menu and press ◄/► until your desired mode is selected.

Maintenance69 Replacing the lamp • If lamp replacement is performed while the projector is suspended upside-down from the ceiling, make sure that no one is underneath the lamp socket to avoid any possible injury or damage to the human eyes caused by fractured lamp. • To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before changing the lamp. • To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before replacing the lamp. • To reduce the risk of injuries to fingers and damage to internal components, use caution when removing lamp glass that has shattered into sharp pieces. • To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, do not touch the empty lamp compartment when the lamp is removed. • This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this lamp in a proper manner. • To assure optimal performance from the projector, it is recommended that you purchase a BenQ projector lamp for lamp replacement. • Ensure good ventilation when handling broken lamps. We recommend that you use respirators, safety glasses, goggles or face shield and wear protective clothing such as gloves. 1. Turn the power off and disconnect the projector from the wall socket. If the lamp is hot, avoid burns by waiting for approximately 45 minutes until the lamp has cooled. 2. Loosen the screw from the right side. 3. Remove the lamp compartment cover as shown.
Maintenance 70 4. Loosen the two captive screws that secure the lamp. • Do not turn the power on with the lamp cover removed. • Do not insert your fingers between the lamp and the projector. The sharp edges inside the projector may cause injuries. 5. Lift the handle so that it stands up. Use the handle to slowly pull the lamp out of the projector. • Pulling it too quickly may cause the lamp to break and scatter broken glass in the projector. • Do not place the lamp in locations where water might splash on it, children can reach it, or near flammable materials. • Do not insert your hands into the projector after the lamp is removed. If you touch the optical components inside, it could cause color unevenness and distortion of the projected images. 6. Insert the new lamp into the lamp compartment and make sure it fits in the projector. • Ensure the connectors are aligned. • If you experience resistance, lift the lamp and start again.
