Introduction12

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 of the projector’s IR remote
control sensors to function correctly. The distance between the remote control and the
sensors should not exceed 6 meters (~ 20 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 battery

1. Pull out the battery holder.

2. Insert the new battery in the holder. Note
the positive polarity should face outward.

3. Push the holder into the remote control
until 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 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 13

Positioning your projector

Choosing a location

Your projector is designed to be installed in one of four possible installation locations:

1. Floor in front of screen;

2. Ceiling in front of screen;

3. Floor at rear of screen;

4. Ceiling at rear of screen.
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.

If you use the projector with wireless function, there's no need to worry about data cable
connections.This gives you the flexibility to site the projector anywhere in the room up to a
range of 20m away from your notebook, and switch between presentations on different
notebooks instantly without fiddling with cables

To use the wireless function, you need to install a BenQ wireless module to the projector and
enable your notebook/desktop PC with wireless connection. For more information, refer to

"Wireless connection (optional)" on page 18.

Positioning your projector14

I. Floor 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.

II. Ceiling front

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 in the Advance > Mirror menu after you turn
the projector on.

III. Floor rear

Select this location with the projector placed near the
floor behind the screen.

Note that a special rear projection screen is required.

Set in the Advance > Mirror menu after you turn

the projector on.

IV. Ceiling rear

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 in the Advance > Mirror 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 maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3
aspect ratio (expressed as 4:3). 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.

Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed
by this projector. This will be seen as darkened (unlit) bars along the top and bottom
(vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a
scaled 16:9 aspect image in the vertical centre of the 4:3 projection display area.

When determining the position of your projector, you should consider its intended use and
input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect
signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height
than that of the scaled 16:9 aspect image projection area).

IMPORT ANT: Do not select a permanent projector position based upon a 16:9 projection if you
will ever need to select an input (other than composite Video being fed a 16:9 aspect signal).

The projector should always be placed horizontally level (like flat on a table), and positioned
directly perpendicular (90° right-angle square) to the horizontal centre 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 diagram 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 centre of the screen (projection distance), and the vertical
offset height of the projector from the horizontal edge of the screen (offset).

Positioning your projector16

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

1. Select your screen size.

2. Refer to the table and find the closest match to your screen size in the left columns
labelled 'Screen Diameter' 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. 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.

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

For example, if you are using a 120 inch screen, the average projection distance is 4691 mm
and with a vertical offset of 46 mm.

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 keystone correction.

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

2. 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.

3. Using this value, look across that row to the left to find the corresponding screen
diameter 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
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 was 4.5m (4500mm), the closest match in
the Average column is 4617mm. Looking across this row shows that a 3000mm (3m) screen
is required. If you can only obtain imperial sized screens, the listed screen sizes on either side
of the 3m screen are the 9' and 10' screens.

Checking the min and max projection distance values for these screen sizes, indicates that
the 4.5m measured projection distance will fit these screens too. The projector can be
adjusted (using the zoom control) to display on these different screen sizes at that projection
distance. Be aware that these different screens have different vertical offset values.

Positioning your projector 17

There is 3%-5% tolerance among these numbers due to optical component variations.

projector (see "Shipping contents" on page 6). They are commercially available
from electronics stores.

Wireless connection (optional)

The Wireless module allows for simultaneous wireless connectivity to multiple computers
which are Wi-Fi enabled. This saves you from having to swap data cables between the
projector and different computers during a presentation. Wi-Fi connectivity is most suitable
for situations where multiple presenters with separate notebooks are required to seamlessly
present individual presentations, like in meetings, conferences, lectures and, classrooms.

The Wireless module connects and attaches to the rear of the projector through the DVI-I
socket.

Whilst the Wireless module is attached to the projector, you cannot use the DVI-I socket for
DVI cable connections.

Even though the projector may be using a wireless data connection, it still requires physical
connection to a power outlet using its power cable.

You can purchase a BenQ wireless module from
BenQ retailers. You should attach the wireless
module to the projector before you connect any
other cables. Refer to the user’s manual
enclosed with the wireless module for
connection and operation details.

Connecting Video source devices

This section describes how to connect the projector to Video source devices using video
cables. Video cable connections are recommended for Video presentations.

This projector also supports data (graphic) "PC" connection using Wi-Fi. Wi-Fi connection is
not recommended for Video presentations. See "Wireless connection (optional)" on page 18.

You can connect your projector to various Video source devices that provide any one of the
following output sockets:

• Component Video

•S-Video

•Video (composite)
You need only connect the projector to a Video source device using just one of the above

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:

Best video quality

The best available video connection method is Component Video (not to be confused with
composite Video). Digital TV tuner and DVD players output Component Video natively, so
if available on your devices, this should be your connection method of choice in preference
to (composite) Video.

See "Connecting a Component Video source device" on page 22 for how to connect the
projector to a component video device.

Better video quality

The S-Video method provides a better quality analog video than standard composite Video.
If you have both composite Video and S-Video output terminals on your Video source
device, you should elect to use the S-Video option.

See "Connecting an S-Video source device" on page 23 for how to connect the projector to
an S-Video device.

Least video quality

Composite Video is an analog video and will result in a perfectly acceptable, but less than
optimal result from your projector, being the least video quality of the available methods
described here.

See "Connecting a composite Video source device" on page 24 for how to connect the
projector to a composite Video device.

Connecting Audio

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

If you wish, you can make use of the projector (mixed mono) speaker in your presentations,
and also connect separate amplified speakers to the Audio Out socket of the projector. The
audio output is a mixed mono signal and controlled by the projector Volume and Mute
settings.

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.

Connection22

The audio connections illustrated in the following sections 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.

Connecting a Component Video source device

Examine your Video source device to determine if it has a set of unused Component Video
output sockets available:

• If so, you can continue with this procedure.

• If not, you will need to reassess which method you can use to connect to the device.

To connect the projector to a Component Video source device (either through
a Component Video to VGA adaptor cable or DVI cable):

The final connection path should be like that shown in the following diagram:

•With a Component Video to VGA
(D-Sub) adaptor cable:

•With a DVI cable:

1. Take the (optional accessory)

Component Video to VGA (D-Sub)
adaptor cable and connect the end
with 3 RCA type connectors to the
Component Video output sockets of
the Video source device. Match the
color of the plugs to the color of the
sockets; green to green, blue to blue;
and red to red.

2. Connect the other end of the

Component Video to VGA (D-Sub)
adaptor cable (with a D-Sub type
connector) to the D-SUB/COMP IN
socket on the projector.

1. Take a DVI cable and connect one
end of the cable to the DVI output
socket of the Video source device.

2. Connect the other end of the cable
to the DVI-I socket on the projector.

3. If you wish, you can use another suitable audio cable and connect one end of the
cable to the AUDIO OUT socket of the projector, and the other end to your
external speakers (not supplied).

On: The pixel resolution of the input signal is converted to the native

resolution of the projector (1024 x 768). For input signals with lower

resolutions, gaps in the pixels are automatically interpolated into the image
before being projected. This may distort the image clarity.

Off: The image is projected as its original resolution, with no pixel conversion.
For input signals with lower resolutions, the projected image will display
smaller than if resized to full screen. You could adjust the zoom setting or move
the projector towards the screen to increase the image size if necessary. You
may also need to refocus the projector after making these adjustments.

Maintenance

Care of the projector

Your projector needs little maintenance. The only thing you need to do on a regular basis is
to keep the lens clean.

Never remove any parts of the projector except the lamp. Contact your dealer if other parts
need replacing.

Cleaning the lens

Clean the lens whenever you notice dirt or dust on the surface.

• Use a canister of compressed air to remove dust.

• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens
cleaner and gently wipe the lens surface.

Never rub the lens with abrasive materials.

Cleaning the projector case

Before you clean the case, turn the projector off using the proper shutdown procedure as
described in "Shutdown" on page 30 and unplug the power cord.

• To remove dirt or dust, wipe the case with the supplied cleaning cloth.

• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH
detergent. Then wipe the case.

Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the
case.

Storing the projector

If you need to store the projector for an extended time, please follow the instructions below:

• Make sure the temperature and humidity of the storage area are within the
recommended range for the projector. Please refer to "Specifications" on page 51 or
consult your dealer about the range.

• Retract the adjuster feet.

• Remove the batteries from the remote control.

• Pack the projector in its original packing or equivalent.

Transporting the projector

It is recommended that you ship the projector with its original packing or equivalent. When
you carry the projector yourself, please use the original box or provided soft carry case.

Cleaning and replacing the dust filter

It is necessary to clean the dust filter periodically. If the filter is not cleaned, it can become
clogged with dust and prevent proper ventilation. This can cause overheating and a
malfunction of the projector.

Maintenance 41

A warning message like the one pictured to
the right will be displayed for 10 seconds
every 500 hours to remind you to clean the
filter. To leave the message, press the Exit
button on the projector or remote control.

To clean the filter:

1. Turn the projector off and wait until the fans stop running.

2. Disconnect the projector from any cables.

3. Locate the filter case on the back of the
projector.

4. Release the filter case from the projector by
pressing the filter case into the slot slightly. The filter case
springs out of the slot.

5. Pull out the filter case.

6. Use a small vacuum cleaner designed for
computers and other office equipment to clean the
filter sponge. Or use a soft brush (such as a clean
artist’s paintbrush) to gently sweep the dust on the
filter away.

If the dirt is difficult to remove or the filter is
broken, replace it with the supplied spare filter
sponge. See "How to replace the filter sponge:"
below.

Please check if the filter is clean

Clean the filter or replace with a new one

Press “Exit” to leave

filter case

Maintenance42

7. Refit the filter case by aligning and inserting it into
the projector slot.

8. Press the case back until it clicks into place.

9. Turn the projector back on.

If the case is not correctly seated in place, the
projector will display an on-screen message as
pictured to the right every three minutes.

The message will display 3 times for a 10-second
duration each, if no further action is taken.

Then a second message as pictured below displays to warn of shutdown in 1 minute.

You can re-attach the case correctly anytime before the projector shuts down. (That
means you have 10-11 minutes to get the re-attachment done from the time the first
warning message was displayed.) The projector will return to normal operation.

How to replace the filter sponge:

If you find the dirt is hard to remove from the filter sponge or the sponge is broken, replace
it.

1. Carefully peel the filter sponge away from the filter case.
See that there are small plastic pins along the edges to
position and retain the sponge into place. Lift the sponge
up off these pins taking care to prevent them from
breaking off.

2. Attach the supplied new filter sponge to the filter case.
Make sure that the tiny holes securely fit onto the case’s
pins.

Please check

Lamp information

Calculation of lamp hour

When the projector is in operation, the duration (in hours) of lamp usage is automatically
calculated by the built-in timer. The method of calculating the equivalent lamp hour is as
follows:

Total (equivalent) lamp hour = 3/4 (hours used in Economic mode) + 1 (hours used in

normal mode)

See "Economic Mode (off)" on page 38 for more information on Economic mode.

The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That is, using
the projector in Economic mode helps to extend the lamp hour by 1/3.

Warning message

When the Lamp indicator lights up red or a message appears suggesting it is time to replace
the lamp, please install a new lamp or consult your dealer. An old lamp may cause a
malfunction in the projector and in some instances the lamp may explode.

For more detailed information on projector warnings, please refer to "Indicators" on page

47.

The Lamp indicator light and Temperature warning light will light up if the lamp becomes too
hot. T urn the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator
still lights up after turning the power back on, please contact your dealer.

The following Lamp warning displays will remind you to change the lamp.

Message Status

The lamp has been in operation for 2800 hours.
Install a new lamp for optimal performance. If the
projector is normally run with "Economic Mode"
selected (See "Economic Mode (off)" on page 38),
you may continue to operate the projector until the
2950 hour lamp warning appears.

The lamp has been in operation for 2950 hours. A
new lamp should be fitted to avoid the
inconvenience of shutdown when the projector runs
out of lamp time.

The lamp has been in operation for over 3000 hours.
This message will flash in the center of the screen for
about 30 seconds together with the Lamp indicator
lighting up red for 40 seconds.

It is strongly recommended that you replace the
lamp at this age. The lamp is a consumable item.
With the usage time increase, the lamp brightness
diminished gradually. You can replace the lamp
whenever you notice that the brightness level has
significantly diminished. If the lamp is not replaced
beforehand, it must be replaced after 3000 hours
usage.

Safety instructions for ceiling mounting of your BenQ
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 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.
