							Introduction 12
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 or wall, we strongly 
recommend that you use a proper fitting BenQ projector ceiling mount kit or 
wall mount kit and that you ensure it is securely and safely installed.
If you use a non-BenQ brand projector mounting kit, there is a safety risk that 
the projector may fall from the ceiling or wall due to an improper attachment 
through the use of the wrong gauge or length screws.
You can purchase a BenQ projector ceiling mount or wall 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 
mounting bracket. This will perform the secondary role of restraining the 
projector should its attachment to the mounting bracket become loose.

Operating the laser pointer
The Laser Pointer is a

professionals. It emits red 
colored light when you press it 
and the indicator lights up red.
The laser beam is visible. It is 
necessary to press and hold 
LASER for continuous output.
Do not look into the laser light 
window or shine the laser light 
beam on yourself or others. 
See the warning messages on 
the back of the remote control 
prior to using it.
The laser pointer is not a toy. Parents 
should be mindful of the dangers of laser 
energy and keep this remote control out of 
the reach of children.

							Introduction 15 Infra-Red (IR) remote control sensor is located on the front of the projector. The 
remote control must be held at an angle within 30 degrees perpendicular to the 
projectors IR remote control sensor to function correctly. The distance between the 
remote control and the sensor should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensor 
on the projector that might obstruct the infra-red beam.

Replacing the remote control battery
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 
comparent. 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 excessive heat and humidity. 
• There may be battery damage if the battery is incorrectly replaced. 
• Replace only with the same or equivalent type recommended by the 
battery manufacturer.
• Dispose of the used battery according to the battery manufacturer’s 
instructions.
• Never throw a battery into a fire. There may be danger of an explosion. 
• If the battery is dead or if you will not be using the remote control for a 
long time, remove the battery to prevent damage to the remote 
control from possible battery leakage.

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 one of four possible 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.
2. Front Ceiling
Select this location with the projector suspended 
upside-down from the ceiling in front of the screen.
Purchase the BenQ Projector Ceiling Mounting Kit 
from your dealer to mount your projector on the 
ceiling.
Set Front Ceiling in the SYSTEM SETUP: Basic 
> Projector Installation menu after you turn the projector on.
3. Rear Table
Select this location with the projector placed near the 
floor behind the screen.
Note that a special rear projection screen is required.
Set Rear Table in the SYSTEM SETUP: Basic > 
Projector Installation menu after you turn the 
projector on.
4. Rear Ceiling
Select this location with the projector suspended 
upside-down from the ceiling behind the screen.
Note that a special rear projection screen and the 
BenQ Projector Ceiling Mounting Kit are required for 
this installation location.
Set Rear Ceiling in the SYSTEM SETUP: Basic > 
Projector Installation menu after you turn the projector on.
You can also use QUICK INSTALL key on the remote 
control to select projector’s location. 
						

							Positioning your projector 18
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting (if available), and 
the video format each factors in the projected image size.
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 diagram on page 19, 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 
proportional to the projection distance.
BenQ has provided a table of 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). 
						

							Positioning your projector 19
Projection dimensions
Refer to Dimensions on page 78 for the center of lens dimensions of this projector 
before calculating the appropriate position.
All measurements are approximate and may vary from the actual sizes. 
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 projectors optical characteristics. This will help you determine 
the exact mounting position so that it best suits your installation location.

							Positioning your projector 20
Shifting the projection lens vertically
The vertical lens shift control provides flexibility for installing your projector. It allows 
the projector to be positioned slightly above or below the top level of the projected 
images.
The lens shift (offset) is expressed as a percentage of the projected image height. It is 
measured as an offset from the projected images vertical center. You can use the 
lever to shift the projection lens upwards or downwards within the allowable range 
depending on your desired image position.
To use the lens shift lever:
1. Release the lever by turning it counterclockwise.
2. Move the lever to adjust the projected image position.
3. Lock the lever by turning it clockwise.
• Please do not over-tighten the lever.
• Lens shift adjustment will not result in a degraded picture quality. In the 
unlikely event that the image distortion is produced, see Adjusting the 
projected image on page 29 for details.
