Precautions with regard to safety WARNING If you notice smoke, strange smells or noise coming from the projector, disconnect the mains plug from the mains socket. 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 Authorised Service Centre for repairs. B Do not attempt to repair the projector yourself, as this can be dangerous.
ENGLISH-7 Preparation Do not do anything that might damage the mains lead or the mains plug. B Do not damage the mains lead, make any modifications to it, place it near any hot objects, bend it excessively, twist it, pull it, place heavy objects on top of it or wrap it into a bundle. B If the mains lead is used while damaged, electric shocks, short-circuits or fire may result. B Ask an Authorised Service Centre to carry out any repairs to the mains lead that might be necessary.
During a thunderstorm, do not touch the projector or the cable. B Electric shocks can result. Do not use the projector in a bath or shower. B Fire or electric shocks can 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 mains plug when you are away from the projector.
ENGLISH-9 Preparation Always disconnect all cables before moving the projector. B Moving the projector with cables still attached can damage the cables, which could cause fire or electric shocks to occur. Do not place any heavy objects on top of the projector. B Failure to observe this may cause the projector to become unbalanced and fall, which could result in damage or injury. Do not short-circuit, heat or disassemble the batteries or place them into water or fire.
Accessories Check that all of the accessories shown below have been included with your projector. Card remote control unit Lithium battery for (N2QADC000008 x1) remote control unit (CR2025 x1) POWER RGB signal cable [1.8 m (5´10˝), K1HA15DA0002 x1] INPUT VIDEO AUTO SETUP RGB MENU ENTER FREEZE SHUTTER STD VOLUME D.
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.

Cleaning and replacing the air filter If the air filter becomes clogged with dust, the internal temperature of the projector will rise, the TEMP indicator will illuminate and the projector’s power will turn off (the TEMP indicator will flash after the power is turned off). The air filter should be cleaned every 100 hours of use. Cleaning Replacement procedure Use a vacuum cleaner to clean off any accumulated dust. # Turn off the power and disconnect the mains lead.
Replacing the lamp unit When replacing the lamp, allow it to cool for at least one hour before handling it. B The lamp cover gets very hot, and touching it can cause burns. Notes on replacing the lamp unit B The light generating lamp is made of glass, so dropping it or allowing it to hit hard objects may cause it to burst. Be careful when handling the lamp.
