Important Operating Considerations for Safety

• Place the projector in a horizontal position
with no greater than 8-degrees forward or
backwards tilt.

• Locate the projector in a well-ventilated
area without any obstructions to intake or
exhaust vents. Do not place the projector on
a tablecloth or other soft covering that may
block the vents.

• Locate the projector at least 4' (1.2 m) away
from any heating or cooling vents.

• Use only Knoll-approved ceiling mounts.
The minimum distance between the ceiling
and a ceiling-mounted projector is 11.8”/30
cm.

• Use only the power cord provided. A surge­protected power strip is recommended.

• Refer to this manual for proper startup and
shutdown procedures.

• In the unlikely event of the lamp rupturing, discard any edible items placed in the surrounding
area and thoroughly clean the area along all sides of the projector.

•Wash hands after cleaning the area and handling the ruptured lamp. This product has a lamp
that contains a very small amount of mercury. Dispose of it as required by local, state or federal
ordinances and regulations. For more information see www.eiae.org.

Follow these instructions to help ensure image quality and lamp life over the life of the projector.
Failure to follow these instructions may affect the warranty. For complete details of the warranty,
see the Warranty section at the end of this User's Guide.

Introduction

Your new Knoll HD225 projector from
Knoll Systems is specifically designed
for home cinema applications. It has
native 1280x720 resolution. The
projector is easy to connect, easy-to­use, and easy to maintain.

*The lens cap tether ships in the Documentation Pack. Attach it to the lens cap and
the projector if desired.

Connector Panel

The projector provides two computer and
four video connectors:

• one M1-D/A (HD, DVI, and computer)

• one VESA (HD, HD component, and
computer)

• one S-video

• one composite RCA

• one component video

It also has an RS-232 serial connector for
serial control. The Command Line
Interface (CLI) specifications and
commands are on our website.

A 3.5mm mini-jack trigger provides 12­volt current. This provides a constant
output while the projector is on. For
example, if you connect your projection
screen to the trigger, when you turn on
the projector the screen will move down;
when you turn the projector off, the
screen will return to the storage position.

You must turn the trigger on in the
System menu, see page 21.

Positioning the projector

There are a number of factors to consider when determining where to set up
the projector, including the size and
shape of your screen, the location of
your power outlets, and the distance
between the projector and the rest of
your equipment. Here are some
general guidelines.

1 Position the projector on a flat
surface at a right angle to the screen.
The projector must be within 10 feet
(3 m) of your power source. To
ensure adequate cable access, place
the projector at least six inches
(0.15m) from a wall or other objects.
Place the projector at least 5.6 feet
(1.7 m) from the projection screen.

If you install the projector on the
ceiling, refer to the installation guide
that comes with the Ceiling Mount Kit
for more information. To turn
the image upside down, see page 21.
Knoll recommends use of an
authorized Knoll ceiling mount. The
Ceiling Mount Kit is sold separately.

2 Position the projector the desired
distance from the screen.

The distance from the lens of the projector to the screen, the zoom setting, and the video format
determines the size of the projected image. For more information about projected image sizes,
see page 26.

The image exits the projector at a given angle. This image offset is 105%. This means that if you
have an image 10’ high, the bottom of the image will be 0.5’ above the center of the lens.

Video connections

You can connect VCRs,
DVD players, camcorders,
digital cameras, video
games, HDTV receivers,
and TV tuners to the
projector. (You cannot
directly connect the coaxial
cable that enters your
house from a cable or
satellite company; the
signal must pass through a
tuner first. Examples of
tuners are digital cable
boxes, VCRs, digital video
recorders, and satellite TV
boxes.

Basically, any device that
can change channels is
considered a tuner.) If there
is more than one output,
select the highest quality
one. DVI, Component video
and RGB (M1, HD15) have
the best quality, followed by
S-video, and then
composite video.

Connecting a video device

If your video device has more than one output, select the highest quality one. DVI video has the
best quality, followed by component video, S-video, and then composite video. If the video device
uses component cable connectors, plug the cable’s green connectors into the green component­out connector on the video device and into the green component connector (labeled “Y”
Component 3) on the
projector. Plug the component
cable’s blue connectors into the
blue component-out connector
on the video device and into the
blue component connector
(labeled “Pb”) on the projector.
Plug the component cable’s
red connectors into the red
component-out connector on
the video device and into the
red component connector
(labeled “Pr”) on the projector.
If you are using RGB input, plug
the additional connector into the
Video 5 connector and turn on
the RGB Video option in the
Sources menu. See page 21. If
the video device uses a round,
four-prong S-video connector,
plug the S-video cable into the
S-video connector on the video
device and into the S-video 4 connector on the projector. Connect the red and white audio
connectors from the A/V cable to your source and Audio In connector on the projector, if desired.

If the video device uses a
yellow composite video
connector, plug the A/V
cable’s yellow connector into
the video-out connector on the
video device. Plug the other
yellow connector into the yellow Video 5 connector on the projector. Connect the red and white
audio connectors from the A/V cable to your source and the projector. If the video device uses a
DVI connector, plug the computer cable into the video-out connector on the video device. Plug
the other connector into the DVI 2 connector on the projector. If the video device uses a VESA
connector, plug a VESA cable into the video-out connector on the video device. Plug the other
connector into the VESA 1 connector on the projector.

Connecting the power cable

Connect the power cable to the
connector on the back of the
projector and to your electrical
outlet. The Power button on the
keypad lights up and the LED on the keypad turns solid green.

NOTE: Always use the power cable that shipped with the projector.

Displaying a video image

Remove the lens cap.

Press the Power button on
the top of the projector or

The fans start to run. When
the lamp comes on, the
startup screen is displayed.
It can take a minute for the
image to achieve full
brightness.

? No startup screen? Get help on page 11.

Plug in and turn on the video
device.

The video device’s image should appear on the projection screen. If it doesn’t, press the Source
button on the keypad or remote.

Adjust the height of the
projector by pressing the
release button to extend
the elevator foot. Rotate the
leveling foot, if necessary.

Position the projector the desired
distance from the screen at a 90-degree
angle to the screen. See 26 for a table
listing screen sizes and distances to the
screen.
