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 and the enclosed 
User Information 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 13
Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the back of the projector. 
The remote control must be held at an angle within 30 degrees perpendicular to the 
projectors IR remote control sensors to function correctly. The distance between the remote 
control and the sensors should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensors on the 
projector that might obstruct the infra-red beam. 
Replacing the remote control batteries
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 manufacturers 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.

Positioning your projector
Choosing a location
Your projector is designed to be installed in one of four possible installation locations: 
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.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 Position 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 Position 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 Position menu after you turn the projector on. 
						

							Positioning your projector 15
Obtaining 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.
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).
The modern digital projector does not project directly forward (like older style reel-to-reel 
film projectors did). Instead, digital projectors are designed to project at a slightly upward 
angle above the horizontal plane of the projector. This is so that they can be readily placed 
on a table and will project forward and upwards onto a screen positioned so that the bottom 
edge of the screen is above the level of the table (and everyone in the room can see the 
screen).
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 pages 17-20, 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 tables of 16:9-aspect-ratio and 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 
screen size
1. Determine the aspect ratio of your screen, 16:9 or 4:3? If you have a 16:9 screen, refer 
to page 17 or 18. If you have a 4:3 screen, refer to page 19 or 20 depending on the 
projected picture aspect ratio you’ve got.
2. Select your screen size.
3. Refer to the table and find the closest match to your screen size in the left columns 
labelled Screen Dimensions. Using this value, look across this row to the right to find 
the corresponding average distance from screen value in the column labelled 
Average. This is the projection distance.
4. On that same row, look across to the right column and make note of the Vertical 
Offset value. This will determine the final vertical offset placement of the projector in 
relation to the edge of the screen.
5. 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 3 
above, and offset by the value determined in step 4 above.
For example, if you are using an 120-inch, 4:3-aspect-ratio screen and the projected picture 
is 16:10, please refer to Table B2
 on page 20. The average projection distance is 4180 mm and 
with a vertical offset of 61 mm.

How to determine the recommended screen size for a 
given 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. Determine the aspect ratio of the screen you need, 16:9 or 4:3? If you need a 16:9 
screen, refer to Table A1
 (page 17) or Table A2 (page 18). If you need a 4:3 screen, refer 
to Table B1
 (page 19) or Table B2 (page 20) depending on the projected picture aspect 
ratio you’ve got.
2. Measure the distance between the projector and where you want to position the 
screen. This is the projection distance.
3. Refer to the table and find the closest match to your measurement in the average 
distance from screen column labelled Average. Check that your measured distance is 
between the min and max distances listed on either side of the average distance value.
4. Using this value, look across that row to the left to find the corresponding Screen 
Dimensions listed in that row. That is the projected image size of the projector at that 
projection distance.
5. On that same row, look across to the right column and make note of the Vertical 
Offset value. This will determine the final placement of the screen in relation to the 
horizontal plane of the projector. 
For example, if you need a 16:9 screen to project a 16:9 picture and your measured 
projection distance was 4.8 m (4800 mm), please refer to Table A1
 on page 17. The closest 
match in the Average column is 4554 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 34 for details.

There is 3% tolerance among these numbers in Table A1, Table A2, Table B1, and Table B2 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 projectors optical characteristics. This 
will help you determine the exact mounting position so that it best suits your installation 
location.
