Important safety instructions
13. Never attempt to replace the lamp assembly until
the projector has cooled down and is unplugged
from the power supply.
Moisture condensation
Never operate the projector immediately after
moving it from a cold location to a hot location.
When the projector is exposed to such a change
in temperature, moisture may condense on the
crucial internal parts. To prevent the projector
from possible damage, do not use the projector
for at least 2 hours when there is a sudden change
in temperature.
14. When you think service or repair is required,
take the projector only to a suitably qualified
technician.
15. 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. See
page 61.
Under no circumstances should you ever undo or
remove any other covers. Refer servicing only to
suitably qualified professional service personnel.
Avoid volatile liquids
Do not use volatile liquids, such as insecticide or
certain types of cleaner, near the projector. Do
not have rubber or plastic products touching the
projector for a long time. They will leave marks on
the finish. If cleaning with a chemically treated
cloth, be sure to follow the cleaning product’s
safety instructions.

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.

Important safety instructions
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:
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
from the ceiling in front of the screen.
Purchase the BenQ Projector Ceiling Mount Kit
from your dealer to mount your projector on the
ceiling.
*Set Front Ceiling after you turn the projector
on.
3. Rear:
Select this location with the projector placed near
the floor behind the screen.
Note that a special rear projection screen is
required.
*Set Rear after you turn the projector on.
4. Rear Ceiling:
Select this location with the projector suspended
from the ceiling behind the screen.
Note that a special rear projection screen and the
BenQ Projector Ceiling Mount Kit are required for
this installation location.
*Set Rear Ceiling after you turn the projector
on.
*To set the projector position:
1. Press MENU/EXIT on the projector or remote control and then press / until the System Setup menu is highlighted.
2. Press / to highlight Projector Position and press / until the correct position is selected.
Important safety instructions
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 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.
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 positions 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.
This projector is equipped with a movable lens. See "Shifting the projection lens vertically" on page 20 for
details. You can see the diagrams on pages 18 and 19 for the vertical offset values in the dimension tables
that are measured when the lens is shifted fully up or down.
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?
2. 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.
3. Decide the exact position of your projector according to the position of your screen and the
adjustable lens shift range.
<Example>
If you are using a 120-inch, 4:3-aspect-ratio screen, please refer to "The screen aspect ratio is 4:3 and the
projected picture is 16:9". The average projection distance is 3409 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 your screen, 16:9 or 4:3?
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 diagonal listed in
that row. That is the projected image size of the projector at that projection distance.
<Example>
If you have a 16:9-aspect-ratio screen and your measured projection distance was 4000 mm, please refer
to "The screen aspect ratio is 16:9 and the projected picture is 16:9". The closest match in the "Average"
column is 4024 mm. Looking across this row shows that a 130-inch screen is required.
Checking the min. and max. projection distance values in the columns of "Projection distance <D> [mm]"
on page 18 indicates that the 4000 mm measured projection distance will also fit the 120 and 140-inch
size screens. The projector can be adjusted (using the zoom control) to display on these different screen
sizes at the projection distance. Be aware that these different screens have different vertical offset values.
16
Important safety instructions
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 picture distortion" on page 34 for details.

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 image's 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.
• When the screen position is fixed
• When the projector position is fixed
• 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 34 for details.

Connecting with video equipment
You can connect the projector to any type of video equipment, such as a VCR, DVD player, Blu-ray player,
digital tuner, cable or satellite decoder, video game console or digital camera. You can also connect it to a
desktop or laptop PC or Apple Macintosh system. You need only connect the projector to a source
device using just one of the connecting methods, however each provides a different level of video quality.
The method you choose will most likely depend upon the availability of matching terminals on both the
projector and the Video source device as described below:

Connecting HDMI devices
HDMI cable
HDMI device: DVD player, digital tuner, etc.
To make sure you select a correct input source
type for the HDMI signal, see "HDMI Settings" on
page 55 for details.
HDMI device: DVD player, digital tuner, etc.
Wireless HDMI transmitter
To connect the HDMI signal, select "Wireless"
from the source selection bar. See "Selecting an
input source" on page 30 for details.
Transmitter USB adapter
• Connecting HDMI devices to the projector with HDMI cables
HDMI (High-Definition Multimedia Interface) supports uncompressed video data transmission
between compatible devices like DTV tuners, DVD players, Blu-ray players and displays over a single
cable. It provides pure digital viewing and listening experience. You should use an HDMI cable when
making connection between the projector and HDMI devices.
• Connecting HDMI devices to the projector wirelessly
You may also make a wireless connection between the projector and HDMI devices. As your
projector is equipped with the built-in HDMI receiver, when you plug the supplied wireless HDMI
transmitter into any HDMI devices, the projector will display the contents from the connected HDMI
source. See "Using the Wireless Transmitter" on page 25 for details.
To prevent signal interference with the projected image, while using this projector, please make sure
that there are no other devices which support 5GHz wireless signals within 3 meters from the
projector, such as access points/routers, wireless cards/dongles, 5.8GHz wireless mouses, 5.8GHz
digital phones, some Wimax products, some Autopass cards, or devices with 802.11AC Wi-Fi.
Since different power of your wireless/radiation devices which operate in the 5GHz frequency band (e.g.
industrial routers or home digital phones, etc.) will potentially impact projected image, the suggested
distance could be over 3 meters away from the projector.
