Basic Information
Congratulations On Your Purchase of the Knöll Projector!
The Knöll DLP is one of the very best projectors available today. It enables you to project
precise images up to 200 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 you'll 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 800 ANSI lumens with small size and 1.3 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 variable, centered at 17.3 degrees.
• Fully compatible with true XGA using advanced intelligent compression technology
The advanced intelligent compression technology of the HT211 enables it to present clear
XGA images without any line omission. The HT201 presents clear S-VGA images.
• The remote control can be used to operate your PC or Macintosh when the supplied
remote mouse receiver is connected.

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 projector 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 all cables connecting to the projector are disconnected before moving the
projector. When moving the projector, cover the lens with the sliding cap.
• Only use your Projector on a solid flat level surface. If the projector falls to the
floor, 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 will harm the
screen 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.
