INSTALLATION AND SETUP
STEP 4 Pull lens assembly out
zCarefully pull the lens assembly straight out of the projector
and set aside.
STEP 5Install new lens assembly
zIMPORTANT:Remove the rear (smallest) lens cap from the new
lens. Make sure the frontlens cap remains on during installation.
zAlign the large cut-out area on the lens flange to the bottomof the
lens mount (which has a matching cut-out). The 3 lens assembly slots
should align with the lens mount screws so that the screw heads will fit...

INSTALLATION AND SETUP
STEP 6Adjust Image
zZOOM:With the input image displayed, rotate the textured ring on the
lens barrel to increase or decrease the image size (this requires a zoom
lens). If you do not have a zoom lens or you can not adjust the image
enough, the projector may not be positioned at the proper throw distance
for your screen size. Power down, unplug the projector and move it
towards or away from the screen.
zFOCUS:At the lens opening, turn the focus tab to focus the image
clearly....

2.3 Installation Considerations
Although this projector delivers a high brightness quality output, final display quality could be
compromised if the projector is not properly installed. This subsection discusses issues you
should consider before proceeding with a final installation. Even if you do not intend to use the
projectors in a fixed and permanent installation, this subsection will help you to better understand
what you can do to enhance display performance.

TheVX-4c/VX-6c 720Psystem offers high definition resolution in a 16:9 format, while providing multiple
aspect ratio selection. Without the use of an anamorphic system. 
The VX-4c/VX-6c 960Psystem provides a 26% increase in brightness and resolution over the base 720P con-
figuration. (Using a 1.33 x Anamorphic lens)
The VX-4c/VX-6c 1024Psystem yields digital cinema resolution by employing every available pixel for a max-
imum picture clarity and brightness. (Using a 1.42 x Anamorphic lens)

Always consult this section when planning a projector installation. See also section 2.7 and 2.8, Projector
Position and Mounting.
Calculating Throw Distance
Correct throw distance depends on the screen size and lens present-the larger the image needed,
the greater the distance you must allow between the lens and screen. Once you know the screen
size and lens type present, you can calculate the precise throw distance you require by using the
appropriate formula as found in this appendix.

2.6 Vertical & Horizontal Position
THE VERTICAL POSITIONof the projector in relation to the screen also depends on the size
of the screen and the lens type. Correct vertical position helps ensure that the image will be rec-
tangular in shape rather than keystoned (having non-parallel sides) and that image focus and
brightness both remain optimized.
In addition, vertical position of the image can be manually offset-that is, moved up or down-by
turning the top screw on the front of...

INSTALLATION AND SETUP
Maximum Vertical Offsets (ZOOM LENSES)
NOTES: 1)If you cannot raise or lower the image enough using
mechanical vertical offsets, try adjusting V-Shiftin the Scaling
Parametersmenu (see 3.6, Adjusting the Image). 2)If the image
becomes keystoned or exhibits uneven brightness, the projector
may simply be too high or low in relation to the screen. 
3) Recommended offset ranges can be exceeded, however this may
affect image quality. 4)Simultaneous horizontal and vertical 
offset limits...

INSTALLATION AND SETUP
2.7 Mounting
For typical front or rear floor mounts, mount the projector on a secure table
or cart. Take care with a mobile cart-avoid sudden stops, excessive force and
uneven surfaces that may cause the projector and cart combination to over-
turn.
The table or cart should be reasonably level. Fine adjustments to the projec-
tor level can be made by adjusting the height of the projector legs.
Special Mounting
Note that projector can be rotated and mounted at any vertical...

Folded Optics
In rear screen applications where space behind the pro-
jector is limited, a mirror may be used to fold the opti-
cal path. The position of the projector and mirror must
be accurately set-if considering this type of installation,
call your Runco dealer for assistance.
2.9 Source Connections
The rear panel of the projector provides standard input panels to which you may connect a vari-
ety of sources. See below - the lower left area (INPUT 1) typically accepts an RGB signalfrom
an external...

INSTALLATION AND SETUP
RGB Signals
INPUT 1provides 5 BNCs (connectors) for linking to a variety of sources. The typical connec-
tion would be to an RGB source such as the VHD Ultra Controller, computers or DTV decoders
with an RGB output. This projector supports multiple sync types with RGB signals: sync-on-
green, composite sync, and separate H & V syncs.
NOTES: Depending on the source, you may need a custom adapter cable that has BNC connec-
tors at the projector end and a different type of connector...
