4. To avoid reduced image quality, do not touch projection lens or other internal

optical components.

5. Do not use detergents, chemicals, or any spray liquids for cleaning this unit, other

than those referred to in the “Operators Guide”.

Guide”.

8. Keep all ventilation openings free of any obstructions.

9. In some countries, the line voltage is NOT stable. This projector is designed to

operate safely within a bandwidth of 100 to 120 volts / 220 to 240 volts (50 to 60

Hz) ±10%, but could fail if power drops or surges of ±10 volts occur. In these high-

risk areas, it is recommended to install a power stabilizer unit.

10. Do not block intake or exhaust air vents. This will cause the projector to over heat

and shut down.

11. Do not place the projector in direct sunlight or near a hot object such as a heater.

12. To prevent damaging the projector, always hold the projector whenever using the

elevator buttons to adjust the elevator feet.

13. Use the accessory cable or a designated-type cable for the connection. Some

cables have to be used with core set. A too long cable may cause certain picture

degradation. Please consult with your dealer for details. For cables that have a

core only at one end, connect the core to the projector.

14. Make sure that you connect devices to the correct port. Incorrect connection may

result in malfunction and/or damage to the device and/or projector.

15. Do not place the projector in the side/front/rear-up position, except care of the air
