WARNING
 Make sure the lens cap is on
before removing or installing a lens assembly.
Grasp the lens assembly near the point where it enters the projector and slowly
unscrew (counter-clockwise) until the assembly is free from the projector. Use
both hands and take care not to touch the lens surface, which is easily damaged.
Set aside.
Make sure the new lens is protected by the lens cap. Install the new lens in the
projector by carefully screwing the assembly into the projector just until snug. If
the lens assembly seems difficult to turn, it may be cross-threaded. Carefully
remove and try again. Use both hands and do not force or over-tighten.
Remove lens cap and reposition the projector closer to or further from the screen
as necessary for the screen and new lens type. For example, if using a 1.2:1 lens,
throw distance should be roughly equal to 1.2 
x the screen width. Adjust vertical
offset as necessary so that display is rectangular.
If the projector is not operating properly, note the symptoms of the problem and
use the following guide to assist you. If you cannot resolve the problem yourself,
contact your dealer for assistance.
The power cord will not fit into the power socket...
1.  A standard power cord is inadequate for the power requirements of the
VistaPro 2000 and will not fit into the projectors power socket. Use only the
notched power cord that came with the projector.
The projector will not turn on when 
 is pressed...
1.  Make sure that 
 is held down for approximately one second and that
the projector has been off for at least 2 minutes.
2.  Are both LEDs OFF on at the back of the projector? Check that the power
cord is properly connected at the both the wall outlet and the projector.
3.  Does the green Status LED flash with each key press? If not, VistaPro
2000 is not receiving the keypads IR signals. Ensure the keypad is directed
at either the front or rear of the projector, or at the screen. Also make sure
that the path between the IR keypad and the projector (or screen) is not
blocked.
4.  The batteries in the IR remote keypad may be weak. Refer to 4.3, Replacing
Keypad Batteries for instructions.
5.  The IR keypad may have been disabled by a change in protocol. See 2.10,
Keypad Protocols and 3.6, Controlling System Parameters.
6. Use the 
 key on the built-in keypad to turn the projector on.
The projector is on but there is no display of source input...
1.  Is an active source connected properly? Check the cable connections. Is that
source selected? Press  
, ,  ,
 or   to select a source. Or
use 
 to switch to other sources. See 2.4, Source Connections and 3.5,

2.  The room lighting may be too bright. Lower the intensity of the room
lighting. Reduce light reflections as much as possible.
3.  Increase contrast and/or brightness of image.
4.  The projector may be too far from the screen. Move the projector closer to
the screen.
5.  Is the Status LED flashing a pattern of yellow and red lights while the
Power LED is steady red? This pattern indicates an internal system error.
If the problem persists contact a qualified Electrohome service technician.
6.  Was the lens cover accidentally left on? Remove lens cover.
The projector does not respond to the infrared remote keypad...
1.  Does the green Status LED flash each time a key is pressed? If not,
VistaPro is not receiving the keypads IR signals. Ensure the keypad is
pointed either at the front or rear of the projector, or at the screen.
2.  The viewing path between the IR keypad and the projector (or screen) may
be blocked. Ensure there is a clear line-of-sight between the keypad and the
projector (or screen).
3.  The batteries in the IR remote keypad may be weak. Refer to 4.3, Replacing
Keypad Batteries for instructions on how to replace the batteries.
4.  There may be unusual lighting conditions in the room affecting IR keypad
operation. Determine if such conditions exist and correct.
5.  The IR keypad may have been disabled for use with this projector(s). See
2.10, Keypad Protocols and 3.7, Controlling System Parameters.
The power is on but the lamp is not...
1.  The projector probably became overheated. Allow to cool and make sure that
nothing blocks projector vents. Do not operate in environments warmer than
35°C (95°F).
2.  The lamp may have reached the end of its 750-hour life. Replace the lamp
assembly as described in 4.4, Replacing the Lamp and Filter.
The display is jittery or unstable...
1.  If the display is jittery or if it disappears and reappears erratically, check that
the source is properly connected and that its signal is of adequate quality for
detection. For example, the projector scans the default input 
 for a
signal to display. If a poor quality or improperly connected source is
connected, the projector will briefly and repeatedly attempt to display an
image. If no source is connected, the No signal present error message
appears over a blank display. Correct the source connection.
2.  The horizontal or vertical scan frequency of the input signal may be out of
range of the projector. Refer to Section 5, Specifications for scan frequency
ranges.
3.  Sync signal may be inadequate. Correct the source problem.
4.  The input signal type may conflict with the input module. Install the correct
module to match that of the source.
5.  Pixel tracking and phase may need adjustment. Symptom

							Appendix A
Glossary
VistaPro 2000 Users Manual A-1
This appendix defines the specific terms used in this manual as they apply to VistaPro 2000. Also included are
other general terms commonly used in the projection industry.
The time, inside one horizontal scan line, during which video is generated.
The ability of a screen to reflect ambient light in a direction away from the line
of best viewing. Curved screens usually have good ambient light rejection. Flat
screens usually have less ambient light rejection.
The video output of most computers and video tape machines. Analog video can
generate a large number of colors.
The ratio of the width of an image to its height, such as the 4:3 aspect ratio
common in video output.
The ability of the projector to automatically synchronize to the horizontal and
vertical scan frequencies of an input signal.
The frequency range of the projectors video amplifier.
The speed at which serial communications travel from their origin. The VistaPro
2000 default baud rate of 9600 can be changed to match a controlling device.
The time inside one scan line during which video is not generated. The blanking
time of the input signal must be equal to or greater than the retrace time of the
projector.
In projection, brightness usually describes the amount of light emitted from a
surface such as a screen. It is measured in foot-lamberts or candelas per square
meter.
Unit of measure for measuring intensity of light.
A menu item that indicates whether an option is currently in effect (checked) or
not (unchecked).
A change in the tint of a white field across an image.
The coloration (reddish, white, bluish, greenish, etc.) of white in an image,
measured using the Kelvin (K) temperature scale. Higher temperatures output
more light. Active Line Time

The output of video tape players and some computers, characterized by
synchronization, luminance and color signals combined on one output cable.
The degree of difference between the lightest and darkest areas of the image.
The alignment of the red, green, and blue elements of a projected image.
The settings (stored in memory) used to display an image from the current
source.
A projection screen which is slightly concave for improved screen gain. Curved
screens usually have screen gains which are greater than 1 but viewing angles
much less than 180
°.
Digital Micro-mirror Devices
Ô used in the VistaPro 2000 for processing red,
green, and blue color data.
A device in the North American VistaPro 2000 that converts NTSC 3.58, NTSC
4.4, PAL, PAL-N, PAL-M, or SECAM to RGB video.
The sharpness of a display from a video source.
A type of rear-projection screen which spreads the light striking it. Screen gain is
less than 1 but audience viewing angles are increased.
An adjustment that affects the display of an image. Such display settings include
contrast, brightness, tint, blanking, focus, etc.
A very rapid variation in image brightness caused by a frame rate that is too
slow. (See Interlace.)
The frequency at which complete images are generated. For non-interlaced
signals, the frame rate is identical to the vertical frequency. For interlaced
signals, the frame rate is one half of vertical frequency.
The intensity of visible light per square foot.
The luminance (brightness) which results from one foot-candle of illumination
falling on a perfectly diffuse surface.
The ability of a screen to direct incident light to an audience. A flat matte white
wall has a gain of approximately 1. Screens with gain less than 1 attenuate
incident light; screens with gain more than 1 direct more incident light to the
audience but have a narrow viewing angle. For example: An image reflecting off
a 10 gain screen appears 10 times brighter than it would if reflected off a matte
white wall. Curved screens usually have larger gain than flat screens.
A display of help information on the projection screen.
The frequency at which scan lines are generated, which varies amongst sources.
Also called horizontal scan rate or line rate.
A circular area of a screen where the image appears brighter than elsewhere on
the screen. The hot spot always appears along the line of sight and moves with Composite Video

the line of sight. High gain screens and rear screens designed for slide or movie
projection usually have a hot spot.
A physical connection route for a source (input) signal.
Signal sent from a source to the projector.
A device that accepts an input signal for display by the projector.
A method used by video tape players and some computers to double the vertical
resolution without increasing the horizontal line rate. If the resulting frame rate
is too low, the image may flicker depending on the image content.
A small push-button device which allows the user to control projector settings
and operation. There are three different VistaPro 2000 keypads: built-in, IR
remote, and wired remote (optional). For more information, refer to 3.3, Using
the Keypads.
A distortion of the image which occurs when the top and bottom borders of the
image are of different lengths. Side borders slant in or out, producing a keystone
shaped image.
The reproduction of the horizontal and vertical size of characters and/or shapes
over the entire screen.
When light from a projector is incident on a screen, the light reflects from the
screen such that the angle of reflection equals the angle of incidence. The Line
of Best Viewing is along the line of reflection.
The method of feeding a series of high impedance inputs from a single video
source with a coaxial transmission line in such a manner that the line is
terminated with its characteristic impedance at the last input on the line.
The amount of visible light emitted by a light source is measured in lumens.
The amount of visible light per square meter incident on a surface.
1 lux = 1 lumen/square meter = 0.093 foot-candles
A list of selectable options displayed on the screen.
A video output format of some video tape and disk players. There are two types
of NTSC (National Television Standards Committee) video: NTSC 3.58 and
NTSC 4.43. NTSC 3.58 is used primarily in North America and Japan.
NTSC 4.43 is less commonly used.
A type of rear-projection screen which re-directs light through the screen to
increase image brightness in front of the screen. Screen gain is usually greater
than 1 but audience viewing angles are reduced.
PAL (Phase Alternating Line) video is a 50 Hz standard with 768 x 576
resolution. It is found on some video tape and disk players (used primarily in
Europe, China and some South American and African countries).
