16. Do not look straight at the projector lens during operation. The intense light beam may damage your

eyes.

17. Refer servicing to qualified service personnel.

18. Always remove the lens cap when the projector lamp is on.

19. In some countries, the line voltage is NOT stable. This projector is designed to operate safely within a

mains voltage between 100 to 240 volts AC, but could fail if power cuts or surges of ±10 volts occur. In areas where the voltage may fluctuate or cut out, it is recommended that you connect your projector through a power stabilizer, surge protector or uninterruptible power supply (UPS).

20. Do not block the projection lens with any objects when the projector is under operation as this could

cause the objects to become heated and deformed or even cause a fire. To temporarily turn off the lamp, press BLANK on the projector or remote control.

21. The lamp becomes extremely hot during operation. Allow the projector to cool for approximately 45

minutes prior to removing the lamp assembly for replacement.

22. Do not operate lamps beyond the rated lamp life. Excessive operation of lamps beyond the rated life

could cause them to break on rare occasions.

23. Never replace the lamp assembly or any electronic components unless the projector is unplugged.

24. Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining serious

damage.

25. Do not attempt to disassemble this projector. There are dangerous high voltages inside which may

cause death if you should come into contact with live parts. The only user serviceable part is the lamp which has its own removable cover. Under no circumstances should you ever undo or remove any other covers. Refer servicing only to suitably qualified professional service personnel.

26. Do not place this projector in any of the following environments.

- Space that is poorly ventilated or confined. Allow at least 50 cm clearance from walls and free flow of air around the projector.

- Locations where temperatures may become excessively high, such as the inside of a car with all windows rolled up.

- Locations where excessive humidity, dust, or cigarette smoke may contaminate optical components, shortening the projector’s life span and darkening the picture.

- Locations near fire alarms.

- Locations with an ambient temperature above 40°C / 104°F

- Locations where the altitudes are higher than 3000 m (10000 feet).

27. Do not block the ventilation holes. If the ventilation holes are seriously obstructed, overheating inside the projector may result in a fire.

- Do not place this projector on a blanket, bedding or any other soft surface.

- Do not cover this projector with a cloth or any other item.

- Do not place inflammables near the projector.

28. Always place the projector on a level, horizontal surface during operation. - Do not use if tilted at an

angle of more than 10 degrees left to right, nor at angle of more than 15 degrees front to back. Using the projector when it is not fully horizontal may cause a malfunction of, or damage to, the lamp.

29. Do not stand the projector on end vertically. Doing so may cause the projector to fall over, causing

injury or resulting in damage to the projector.

30. Do not step on the projector or place any objects upon it. Besides probable physical damage to the projector, doing so may result in accidents and possible injury.

31. Do not place liquids near or on the projector. Liquids spilled into the projector may cause it to fail. If

the projector does become wet, disconnect it from the power supply’s wall socket and call your local service center to have the projector serviced.

32. When the projector is under operation, you may sense some heated air and odor from its ventilation

grill. It is a normal phenomenon and not a product defect.

33. Do not use the Security bar for transporting or installation. It should be used with a commercially

available theft prevention cable.

Introduction

Projector features

The projector integrates high-performance optical engine projection and a user-friendly design to deliver high reliability and ease of use. The projector offers the following features.

• Short throw projection.

• Screen Color correction allowing projection on surfaces of several predefined colors

• Quick auto search speeding up the signal detecting process

• Digital keystone correction to correct distorted images

• Ability to display 16.7 million colors

• Multi-language On-Screen Display (OSD) menus

• Component HDTV compatibility (YPbPr) (optional)

• The apparent brightness of the projected image will vary depending on the ambient lighting conditions,

selected input signal contrast/brightness settings, and is directly proportional to projection distance.

• The lamp brightness will decline over time and may vary within the lamp manufacturers’ specifications.

This is normal and expected behavior.

Positioning your projector

Choosing a location

Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment. Your projector is designed to be installed in the following installation locations:

1. Front Table

Select this location with the projector placed near the floor in front of the screen. This is the most common way to position the projector for quick setup and portability.

Projection dimensions

Refer to "Dimensions" on page 35 for the center of lens dimensions of this projector before calculating the appropriate position.  4:3 image on a 4:3 screen

There is 3% tolerance among these numbers due to optical component variations. It is recommended that if you intend to

permanently install the projector, you should physically test the projection size and distance using the actual projector in situ

before you permanently install it, so as to make allowance for this projector's optical characteristics. This will help you

determine the exact mounting position so that it best suits your installation location.
