Other considerations and tips which can help you improve your installation:
• Ventilation is an important factor when preparing a projection room. The ambient
temperature should be kept constant and below 35°C (95°F). Keep the projector
away from heating and/or air conditioning vents. Changes in temperature can
cause drifts in the projector circuitry which may affect performance.
• Keep the projector away from devices which radiate electromagnetic...

Installation type, screen type, and lighting all affect where the projector is positioned.
In addition, both throw distance (the distance between the projector and screen) and
vertical position (the height of the projector in relation to the screen) must be
determined for every new installation. Both depend on the screen size and lens type
you are using. Make sure that the room can accommodate the required position of the
projector for the chosen...

with any lens/projector combination. In addition, keep in mind that long throw
distances significantly reduce offset ranges.

NOTES: 1) For any projector, if you cannot raise or lower the image enough using
mechanical vertical offsets, try adjusting V-Position in the Size and Position menu
(see 3.6, Adjusting the Image) when displaying at less than the maximum size. 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

horizontal and vertical offset can limit the adjustment range of each.
THE HORIZONTAL POSITION of the image can be offset—that is, shifted left or right
of lens center—by using the 
Lens key. This displays the Lens Control menu, where
offsets can be adjusted with

You must use the proper ceiling mount fixture or stacking kit for your projector. For
more information, contact your dealer.
In rear screen applications where space behind
the projector is limited, a mirror may be used to
fold the optical path (see right). The position of
the projector and mirror must be accurately set—
if considering this type of installation, call your
dealer for assistance. Folded O...

The front panel of the projector provides standard input panels to which you may
connect a variety of sources. See Figure 2.17–the lower left area (
INPUT 1) typically
accepts an RGB signal from an external RGB source, or it can also be used for YPbPr
signals or additional video sources. The upper right panel–the Video Decoder
Module–accepts only composite video at 
INPUT 3 or S-video at INPUT 4 from devices
such as VCRs, laser disk players or DVD...

INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources. The typical
connection would be to an RGB source such as VGA, SVGA, XGA, Mac,
PowerMac, DEC, Sun, SGI and others. This projector supports multiple sync types
with RGB signals: sync-on-green, composite sync, and separate H & V syncs.
NOTE: Depending on the source, you may need a custom adapter cable with BNC
connectors at the projector end and a different type of connector at the...

Connect a YPbPr signal (component video) to INPUT 1 as shown in Figure 2.19.
Figure 2.19. Connecting YPbPr Signal
NOTES: 1) If, for some reason, the projector fails to recognize a YPbPr signal,
specify this Color Space option within the Image Settings menu. See 3.6, Adjusting
the Image. 2) Do not connect digital component signals (known as YCbCr) to 
INPUT

The video decoder input panel provides simultaneous connection of both a composite
video source (
INPUT 3) and an S-Video source (INPUT 4).
If connecting an S-Video source, use the 4-pin mini DIN connector or the Y and C
BNC connectors (luma and chroma) at 
INPUT 4–do not use both as inputs. See Figure
2.21.

device, see Video Loop...
