Safety Instructions (Continued)

7. The lamp becomes extremely hot during operation. Allow the projector to cool for approximately 45 minutes prior to removing the lamp assembly for replacement.

8. 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.

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

11. 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.

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

Important safety instructions4

12. 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.

Safety Instructions (Continued)

13. 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, shorten the projector's life span and darken the image.

- 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).

14. Do not block the ventilation holes.

- 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.

If the ventilation holes are seriously obstructed, overheating inside the projector may result in a fire.

15. 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.

17. 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.

18. 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 power outlet and call BenQ to have the projector serviced.

19. This product is capable of displaying inverted images for ceiling mount installation.

Use only BenQ's Ceiling Mount Kit for mounting the projector and ensure it is securely installed.

Ceiling mounting the projector

Ceiling mounting the projectorCeiling mounting the projector

We want you to have a pleasant experience using your BenQ projector, so we need to bring this safety matter to your attention to prevent possible damage to person and property.

If you intend to mount your projector on the ceiling, we strongly recommend that you use a proper fitting BenQ projector ceiling mount kit and that you ensure it is securely and safely installed.

If you use a non-BenQ brand projector ceiling mount kit, there is a safety risk that the projector may fall from the ceiling due to an improper attachment through the use of the wrong gauge or length screws.

You can purchase a BenQ projector ceiling mount kit from the place you purchased your BenQ projector. BenQ recommends that you also purchase a separate Kensington lock compatible security cable and attach it securely to both the Kensington lock slot on the projector and the base of the ceiling mount bracket. This will perform the secondary role of restraining the projector should its attachment to the mounting bracket become loose.

1. To open the battery cover, turn the remote control over to view its back, push on the finger grip on the cover and slide it up in the direction of the arrow as illustrated. The cover will slide off.

2. Remove any existing batteries (if necessary) and install two AAA batteries observing the battery polarities as indicated in the base of the battery compartment. Positive (+) goes to positive and negative (-) goes to negative.

3. Refit the cover by aligning it with the base and sliding it back down into position. Stop when it clicks into place.

• Avoid leaving the remote control and batteries in an excessive heat or humid environment

like the kitchen, bathroom, sauna, sunroom or in a closed car.

• Replace only with the same or equivalent type recommended by the battery manufacturer.

• Dispose of the used batteries according to the manufacturer's instructions and local

environment regulations for your region.

• Never throw the batteries into a fire. There may be danger of an explosion.

• If the batteries are dead or if you will not be using the remote control for an extended

period of time, remove the batteries to avoid damage to the remote control from possible battery leakage.

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.

Positioning your projector14

Obtaining a preferred projected image size

Obtaining a preferred projected image sizeObtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the projected image size.

4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9 (widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the projector's native aspect width. This will result in a proportionally smaller height equivalent to 75% of the projector's native aspect height.

Darkened bar

(12.5% height)

Darkened bar

(12.5% height)

4:3 aspect image in a 4:3

aspect display area

The projector should always be placed horizontally level (like flat on a table), and positioned directly perpendicular (90° right-angle square) to the horizontal center of the screen. This prevents image distortion caused by angled projections (or projecting onto angled surfaces).

If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects at a slightly downward angle.

You can see from the diagrams on page 17, that this type of projection causes the bottom edge of the projected image to be vertically offset from the horizontal plane of the projector. When ceiling mounted, this refers to the top edge of the projected image.

If the projector is positioned further away from the screen, the projected image size increases, and the vertical offset also increases proportionately.

When determining the position of the screen and projector, you will need to account for both the projected image size and the vertical offset dimension, which are directly proportional to the projection distance.

BenQ has provided a table of 4:3-aspect-ratio screen sizes to assist you in determining the ideal location for your projector. There are two dimensions to consider, the perpendicular horizontal distance from the center of the screen (projection distance), and the vertical offset height of the projector from the horizontal edge of the screen (offset).

How to determine the position of the projector for a given How to determine the position of the projector for a given screen size

screen size

screen sizescreen size

1. Select your screen size.

2. Refer to the table on page 17 and find the closest match to your screen size in the left columns labelled "Screen Size". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled

"Distance from Screen in mm". This is the projection distance.

3. On that same row, look across to the right column and make note of the "Vertical

offset in mm" value. This will determine the final vertical offset placement of the

projector in relation to the edge of the screen.

4. The recommended position for the projector is aligned perpendicular to the horizontal center of the screen, at the distance from the screen determined in step 2 above, and offset by the value determined in step 3 above.

Positioning your projector 15

For example, if you are using an 120-inch screen, the recommended projection distance is 1481 mm and the vertical offset is 137 mm.

How to determine the recommended screen size for a How to determine the recommended screen size for a given distance

given distance

given distancegiven distance

This method can be used for situations where you have purchased this projector and would like to know what screen size will fit in your room.

The maximum screen size is limited by the physical space available in your room.

1. Measure the distance between the projector and where you want to position the screen. This is the projection distance.

2. Refer to the table on page 17 and find the closest match to your measurement in the average distance from screen column labelled "Distance from Screen in mm". This is the projection distance.

3. Using this value, look across that row to the left to find the corresponding "Screen

Size" listed in that row. That is the projected image size of the projector at that

projection distance.

4. On that same row, look across to the right column and make note of the "Vertical

offset in mm" value. This will determine the final placement of the screen in relation to

the horizontal plane of the projector.

For example, if your measured projection distance is 1.5 m (1500 mm), the closest match in the "Distance from Screen in mm" column is 1481 mm. Looking across this row shows that a 120'' (about 3.0 m) screen is required.

If you place the projector in a different position (to that recommended), you will have to tilt it down or up to center the image on the screen. In these situations, some image distortion will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on

page 28 for details.

There is 3% tolerance among these numbers due to optical component variations. BenQ recommends 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.

The projector has two built-in mono speakers which are designed to provide basic audio functionality accompanying data presentations for business purposes only. They are not designed for, nor intended for stereo audio reproduction use as might be expected in home theater or home cinema applications. Any stereo audio input (if provided), is mixed into a common mono audio output through the projector speakers.

If you have a separate sound system, you will most likely want to connect the audio output of your video source device to that sound system, instead of to the mono audio projector. The audio connections illustrated on page 18 are provided for informational purposes only. You need not connect audio to the projector if there is an alternate sound system available, or if audio is not required.
