x Lens Shift Adjustable Range
The top right diagram shows the location of the image position in the lens. The lens can be shifted within the shaded area as shown
using the normal projection position as a starting point.
Maximum Possible Range for GT12ZLB/GT20ZL/GT48ZLB:
Up: 0.5 V (V: height of projected image)
Down: 0.5 V
Right: 0.32 H (H: width of projected image)
Left: 0.32 H
NOTE: Lens shift is not available on the GT06RLB and the GT10RLB rear lens. The GT06RLB and the GT10RLB should be used only for“zero degree/no-offset” applica-tions.
NOTE: If lens is shifted in two directions combined, maximum range in either direction cannot be obtained due to rounded off area of lens. (example: shift up and right)See top right diagram.
2. Installation
WARNING
* Installing the projector on the ceiling must be done by a qualified tech-
nician.
• Tilting the front of the projector up or down by more than 45° from
level could reduce lamp life by up to 20%.
• Only use your projector on a solid, level surface. If the projector falls,
you could be injured and the projector severely damaged.
• Do not use the projector where temperatures vary greatly. The pro-
jector must be used at temperatures between 32°F (0°C) and 95°F
(35°C).
• Do not expose the projector to moisture, dust, or smoke. This will
reduce the quality of the image.
• Ensure that you have adequate ventilation around your projector so
heat can dissipate. Do not cover the vents on the projector.

Maximum Possible Range for GT13ZLB/GT19ZLB/GT24ZLB/GT34ZLB:
Values in parentheses for GT13ZLB.
Up: 0.39V (0.32V) (V: height of projected image)

c Optional Lens Installation
This section describes how to install the lens.
See page 2-8 for installing the GT12ZLB lens and page 2-10 for the GT06RLB lens.
Before installation
* Determine the optional lens to be used to obtain a desired projection distance. There are nine optional lenses available:
GT12ZLB, GT13ZLB, GT19ZLB, GT20ZL, GT24ZLB, GT34ZLB and GT48ZLB (Zoom lens)
GT06RLB and GT10RLB (Short throw fixed-focus lens)
* Press the power button (ON/STAND BY) on the projector or POWER OFF button on the remote control for a minimum of two seconds to turn off the
power, wait 90 seconds (2 minutes in the optional extended life lamp GT60LPS) for the cooling fan to stop, turn off the main power switch then
disconnect the power cable.
Check that the projector has cooled off sufficiently before proceeding.
CAUTION
* The projector and lens contain high-precision parts. Do not induce shock to the projector or the lens.
* Do not touch the lens surface. Doing so can degrade the optical performance.
For installing GT10RLB, GT13ZLB, GT19ZLB, GT20ZL, GT24ZLB, GT34ZLB and GT48ZLB
Preparation: Tools needed for installation:
A hexagonal driver and dust-protective sheets are supplied with the optional lens.
1. Remove the lens hood cap and lens hood.q Remove the lens hood cap.
w Loosen and remove the 2 screws on the lens hood using the hexagonal driver.
e Remove the lens hood by pushing down and pulling the top toward you.

To adjust the focus for the GT06RLB lens, rotate the three knobs on the lens unit.
 1. Rotate the knob (B) to adjust the center focus.
 2. Rotate the knob (C) to adjust the edge focus
 3. Rotate the knob (A) to correct image distortion. The image is slightly out of focus.
 4. Rotate the knobs (B) and (C) again to adjust the center and edge focus.

v Making Connections
NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the power to the notebook PC. In most cases
signal cannot be output from the RGB output unless the notebook PC is turned on after connecting with the projector.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power management software.
* If you accidentally hit the POWER button on the remote control, wait 90 seconds (2 minutes in the optional extended life lampGT60LPS) and then press the POWER
button again to resume.
When Viewing a DVI Digital Signal:
To project a DVI digital signal, be sure to connect the PC and the projector using a DVI-D signal cable (not supplied) before turning on your PC or
projector. Turn on the projector first and select DVI (DIGITAL) from the source menu before turning on your PC.
Failure to do so may not activate the digital output of the graphics card resulting in no picture being displayed. Should this happen, restart your PC.
Do not disconnect the DVI-D signal cable while the projector is running. If the signal cable has been disconnected and then re-connected, an image may
not be correctly displayed. Should this happen, restart your PC.
NOTE:
• Use a DVI-D cable compliant with DDWG (Digital Display Working Group) DVI (Digital Visual Interface) revision 1.0 standard. The DVI-D cable should be within 5 m
(196") long.
• The DVI (DIGITAL) connector accepts VGA (640x480), SVGA (800x600), 1152x864, XGA (1024x768) and SXGA (1280x1024 @ up to 60Hz).

NOTE: For older
Macintosh, use a com-
mercially available pin
adapter (not supplied)
to connect to your
Mac's video port.
Connecting your PC or Macintosh computer to your projector will en-
able you to project your computer's screen image for an impressive pre-
sentation.
To connect to a PC or Macintosh, simply:
1. Turn off the power to your projector and computer.
2. Use a commercially available signal cable to connect your
PC or Macintosh to the projector.
3. Turn on the projector and the computer.
4. If the projector goes blank after a period of inactivity, it may
be caused by a screen saver installed on the computer you've
connected to the projector.
Connecting to RGB 1 IN connectors (BNC)
Use a BNC
5 cable (not supplied) to connect your PC and the RGB 1
IN connectors on your projector.
Connecting to RGB2 IN connector (D-Sub 15 Pin)
Use an RGB signal cable (not supplied) to connect your PC and the
RGB2 IN connector on your projector.
Connecting Your PC with a DVI Connector
Use a DVI-D signal cable (not supplied) to connect a DVI connector of
your PC to the projector.
NOTE: The GT6000/GT5000 is not compatible with video decoded outputs ofeither the NEC ISS-6020 and ISS-6010 switchers.
