Remove the 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
2.5:1 lens, throw distance should be roughly equal to 2.5 
[ the screen width. For
accuracy in a permanent installation, always use the appropriate throw distance
from Appendix E. Power up and test. Adjust vertical offset as necessary so that
display is rectangular.
NOTE: If you install one of the larger Vista lenses you may need to adjust the
lens mount tilt UP slightly to compensate for increased gravitational pull on
these heavier lenses.  On the front bezel of the projector, remove the very small
cap located near the top of the lens (at approximately 11 o’clock). Insert a 9/64”
Allen key until it seats on the internal hex screw—you may have to move the
horizontal offset for access. Turn the screw slightly to adjust the lens tilt UP as
necessary.
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.

4.4, Replacing the Lamp and Filter.
7KH#GLVSOD\#LV#MLWWHU\#RU#XQVWDEOH111
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 
,QSXW4d 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.

This appendix defines the specific terms used in this manual as they apply to VistaGRAPHX 10K. 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 recognize and synchronize to the
horizontal and vertical scan frequencies of an input signal for proper display.
The frequency range of the projectors video amplifier.
The speed at which serial communications travel from their origin. The
Vista
GRAPHX 10K 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 collection of measurements stored by the projector for a given input source,
including frequencies, pulse width, polarity, syncs, channel number and location,
user-adjustable display settings, etc. Use channels to switch between a variety of
inputs quickly, automatically recalling previous display setups.
A list/menu of previously-defined channels available in the projector. $FWLYH#/LQH#7LPH
