							IMPORTANT SAFEGUARDS 
These safety instructions are to ensure the long life of your projector and to prevent fire and 
shock.  Please read them carefully and heed all warnings. 
 
Installation 
• For best results, use your projector in a darkened room. 
• Place the projector on a flat, level surface in a dry area away from dust and moisture or hang it 
from the ceiling with an approved mount kit. 
• Do not place your projector in direct sunlight, near heaters or heat radiating applian\
ces. 
• Exposure to direct sunlight, smoke or steam can harm internal components. 
• Handle your projector carefully.  Dropping or jarring can damage internal components. 
• Do not place heavy objects on top of the projector. 
• If installing the projector in the ceiling: 
− The ceiling must be strong enough to support the projector.  
− The installation must be in accordance with any local building codes. 
− The projector must be installed by qualified Knöll dealer personnel. 
 
Power Supply 
• The Projector is designed to operate on a power supply of 100-120 or 220-240 V 50/60 Hz 
AC.  Ensure the mains power fits this requirement before attempting to use your Projector. 
• Handle the power cable carefully and avoid excessive bending.  A damaged cord can cause 
electric shock or fire. 
• If the projector is not to be used for an extended period of time, disconnect the plug from the 
power outlet. 
 
Cleaning 
• Unplug the projector before cleaning. 
• Clean the cabinet periodically with a damp cloth.  If heavily soiled, use a mild detergent.  
Never use strong detergents or solvents such as alcohol or thinner. 
• Use a blower or lens cloth to clean the lens and be careful not to scrat\
ch the lens. 
 
Lamp Replacement 
• Be sure to replace the lamp when the Status light comes on.  If you continue to use the lamp 
after 1000 hours of use, the lamp will turn off. 
• Allow a minimum of one minute to elapse between turning the lamp off and on.  High 
voltage is applied to the lamp immediately when the power is turned on. Turning the power 
off and quickly back on may shorten the lamp life lamp and result in damage to the projector. 
 
Fire and Shock Precautions 
• Ensure there is sufficient ventilation and the vents are unobstructed to prevent heat buildup 
inside the Projector. Allow at least 10cm (3”) of space between your projector and a wall. 
• Prevent foreign objects such as paper clips and bits of paper from falling into your projector.  
Do not attempt to retrieve any objects that might fall into your projector.  Do not insert any 
metal objects such as a wire or screwdriver into your projector.  If something should fall into 
your projector, disconnect it immediately and have the object removed by a qualified Knöll 
service person. 
• Do not place any liquids on top of your projector. 
• Do not look into the lens while the projector is on.  Serious eye damage\
 could result.

							Basic HT221 Information 
 
Congratulations On Your Purchase of the HT221 Projector! 
 
The HT221 is one of the very best Projectors available today.  The HT221 enables you to project 
precise images up to 300 inches across (measured diagonally) from your PC or Macintosh 
computer (desktop or notebook), VCR, document camera, laser disc player, DVD player, etc. 
The Projector can be placed on a tabletop or cart, or permanently mounted on the ceiling.  You 
may use the Projector to project images from behind the screen.  The supplied remote control can 
be used as wireless control and with the supplied mouse receiver to operate the mouse functions 
on your PC or Macintosh. 
 
The features youll enjoy… 
 
• Compatible with following various color systems: 
− NTSC (U.S. and Canada standard) 
− PAL (Western Europe and Australia/New Zealand standard) 
− SECAM (France and Eastern Europe standard) 
− NTSC4.43 (Middle East country standard) 
• Superior brightness of 1300 ANSI lumens with small size and 2.6 kilograms 
The DMD and our own optical design interact in a geometric effect to increase the light usage 
efficiency.  Now you can reproduce the 3 basic colors (RGB) required for color reproduction 
on a single DMD.  That means superior brightness, smaller size and lighter weight. 
• Sharp, clear images 
There is no RGB color separation, and the spaces between the individual \
pixels are not 
noticeable.  That means sharp and clear reproduction of small characters and figures.  Take a 
closer look and notice the difference in quality! 
• Outstanding beauty when reproducing DVDs and other high picture-quality \
information 
sources 
Faithful gray scale reproduction makes for more natural image displays.  DVD and other high 
quality image sources bring out the true display capacity of the Projector. 
• Screen not distorted to a trapezoid (keystoning) when projecting to the height of the line 
of vision 
Because the projection position is already set to the height of the line of vision, there is no 
distortion of the screen to a trapezoid. Keystone is 13 °, which can be varied. 
• Fully compatible with true XGA using advanced intelligent compression te\
chnology 
The advanced intelligent compression technology of the HT221 enables it to present clear 
XGA images without any line omission. 
• The remote control can be used to operate your PC or Macintosh when the \
supplied 
remote mouse receiver is connected.

							Remote Control 
 
Inserting the batteries 
1) Press firmly and slide 
the battery cover off. 
2) Insert the supplied two 
batteries (size AA/R6).  
Ensure that the 
polarities (+ and -_) of 
the batteries are 
aligned correctly. 
Always replace 
batteries with fresh 
alkaline type. 
3) Slip the cover back 
over the batteries until 
it snaps into place. 
 
Notes 
• If the remote control 
gets wet, wipe it dry 
immediately. 
• Avoid excessive heat 
and humidity. 
• If you will not be using 
the remote control for a 
long time, remove the 
batteries. 
• Do not mix new and 
old or different types of 
batteries. 
• There are operations that 
can only be carried out by 
remote control. Handle 
the remote control 
carefully. 
 
Remote control effective 
range 
Each side of the projector 
has a remote sensor.  The controllable range is 50 degrees horizontally and 30 degrees vertically 
relative to a line that is at a right angle to the remote sensor.  And the distance between the point 
of the remote control and remote sensor must be no more than four to five meters (about 15’).

Projector Part Identification 
  
 
 
 
 
 
Installation 
The distance from the projector lens to the screen determines to the size of the projected 
image, therefore, you need to consider the place where you set up the proj\
ector and 
screen before making connections.  You also need to consider the screen size and height \
of the unit and screen as other important factors. 
 
Tip: Although not advised, a non-glossy wall may be used as a substitute for a screen.

WARNING 
• Carrying The Projector 
Ensure that the power cord and any other cables connecting to video sour\
ces are 
disconnected before moving the projector.  When moving the projector or when it is 
not in use, cover the lens with the lens cap. 
• Only use your Projector on a solid flat level surface.  If the projector\
 falls to the 
ground, you can be injured and the projector severely damaged. 
• Do not use the Projector where temperatures vary greatly.  The projector must be used 
at temperatures between 5 degree Celsius (41 degree Fahrenheit) and 35 degree\
 
Celsius (95 degree Fahrenheit). 
• Do not expose the Projector to moisture, dust, or smoke.  This may harm the image. 
• Ensure that you have adequate ventilation around your Projector to allow\
 heat 
dissipation.  Do not cover the vents on the bottom or the side of the projector. 
 
Projector Positioning 
The projected image becomes larger as the distance between the unit and screen 
increases.  The minimum image size is about 25 inches (0.64m) diagonally at a distance 
of about 1.2m (3.9 feet) and the maximum size is about 300 inches (7.6m) at a distance of 
12.3m (40.4 feet) from the screen.
