Lenses that can be used are a 3 : 1 ~ 7 : 1 zoom lens and a 1.5 : 1 fixed-focus lens. With a zoom lens used, you have a wider
latitude in selecting projection distance and installation space than with a fixed lens.
For how to install the lens, consult the dealer who installed and adjusted your projector or service center.
Relationship of screen width vs. projection distance
In the shaded areas in the above graph, the projected image may be partially distorted or
missed out depending on the distance between the projector and the screen. To project an image
with no image distortion or missing, we recommend you to use the projector in the areas defined
with solid lines in the graph.
The numbers in ( ) represent the minimum to maximum adjustable range.

Connecting to Various Devices
The following signals can be input to the projector:
■ Video signals
(1) Response to color systems
*
1
: Responds if Y/C output is available.
*
2
: Signifies that component signals (“Y, PB, PR ” / “ Y, B-Y, R-Y” / “G, B, R, H/CS, V”) conform to the signal timing (synchroniza-
tion and video period) of each color system. The color systems are used for convenience only.
*
3
:To use these terminals, a video board (separately sold) is required.
(2) Response to double density (*1), high-vision signals

: Signals whose density of scanning lines/field is twice as high.
*
2
: Responds to signals whose horizontal scanning frequency is 31.5 kHz. NTSC can be made twice as dense by a line doubler
(separately available: recommended article). Also, possible to respond to fully-specified, decoded 525P progressive sig-
nals.

: Responds to signals whose horizontal scanning frequency is 33.5 kHz. PAL can be made twice as dense by a line doubler
(separately available: recommended article).

Signals that Can Be Input to the Projector
*Before connection, be sure to turn off the projector and connected devices.
*Read the manual which comes with each device thoroughly.
Notes
• Interlace signals are not handled.
• Some signals other than listed above can be displayed. But they require adjustment. Even some of the signals listed above may require
adjustment depending on the video board used.
• When a signal other than listed above is input, the screen could be partially erased or an unneeded fold-over screen could appear.
• Even signals in the frequency range that can be input may not be displayed normally depending on the type of the signal.
• Composite sync.(Cs) and G on sync. signals can not handled depending on the devices connected.
