Check that all of the accessories shown below have been included with your projector.

Before use

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. In order to get the best picture quality Draw curtains or blinds over any windows and turn off any fluorescent 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 accessory lens cover. About the screen Do not apply any volatile substances which may cause discolouration to the screen, and do not let it become dirty or damaged. About the lamp The lamp may need to be replaced earlier due to variables such as individual lamp characteristics, usage conditions and the installation environment, especially when the projector is subjected to continuous use for more than 10 hours or the power is frequently turned on and off.
Cautions regarding setting-up

Avoid setting up in places which are subject to vibration or shocks. The internal parts can be damaged, which may cause malfunctions or accidents. Do not set up the projector near high-voltage power lines or near motors. The projector may be subject to electromagnetic interference. If installing the projector to the ceiling, ask a qualified technician to carry out all installation work. You will need to purchase the separate installation kit (Model No.ET-PKC80). Furthermore, all installation work should only be carried out by a qualified technician. If using this projector at high elevations (above 1400 m), set the FAN CONTROL to HIGH. (Refer to page 43.)

Lamp indicator warning light
Lamp unit replacement period
The lamp is a consumable product. Even when the full life of the bulb has not been exhausted, the brightness of the light will gradually decline. Therefore periodic replacement of the lamp is necessary. The intended lamp replacement interval is 2000 hours, but it is possible that the lamp may need to be replaced earlier due to variables such as a particular lamps characteristics, usage conditions and the installation environment. Early preparation for lamp replacement is encouraged. A lamp that has exceeded 2000 hours of use has a much greater chance of exploding. In order to prevent the lamp from exploding, the lamp will be automatically shut off when 2000 hours of use have been reached. NOTE: B The usage hours explained above are for use when the HIGH setting has been selected for LAMP POWER in the OPTION2 menu. If the LOW setting is selected, the brightness of the lamp will be less and life of the lamp can be extended. B While 2000 hours is the intended replacement interval, it is not a period of time covered by warranty. More than 1800 hours Displayed for 30 seconds. Pressing any button will clear the display. This display cannot be cleared at all, no matter which button is pressed. The projector will enter Standby Mode and the red indicator lamp will illuminate.
