Remote Control Notes
¥ Use the remote control within a distance of about 7m (23feet)
and at an angle of 30û above, below, to the left and to the right of
the remote control sensor located at the front of the main unit.
¥ The remote control system may not function when direct
sunlight or strong illumination strikes the remote control sensor
of the main unit, or when there is an obstacle in the path.
¥ When remote control buttons are pressed and held, main unit
function keys may not operate.
¥ Do not subject to strong shock.
¥ Do not allow water or other liquid to splash on the remote
control. If the remote control gets wet, wipe it dry immediately.
¥ Avoid exposure to heat and steam.
¥ Remove the batteries from the remote control when the remote
control is not going to be used for a long period.
You cannot operate the projector using the remote con-
trol if:
¥ the remote ID is not set to [00].
¥ the remote ID is not the same as the projector ID.
See page E-43 for setting remote ID and page E-38 for setting
projector ID.
Attaching the supplied ferrite clamp
The ferrite clamp is provided with this projector in order to reduce
electromagnetic interference that may cause interference to radio
communication.
1. Push the catch and open the ferrite clamp.
2. Draw the remote cable through the hole and wind the remote
cable around the ferrite clamp two times, then close the ferrite
clamp. Place the ferrite clamp as closely to the end of the cable
that plugs into the projector as possible.

INSTALLATION 2
This section describes how to set up your MultiSync GT2000/
GT2000R LCD projector and how to connect video and audio
sources.
Setting Up Your MultiSync GT2000/
GT2000R LCD Projector
Your MultiSync GT2000/GT2000R LCD Projector is simple to
set up and use. But before you get started, you must first:
1. Determine the image size
2. Set up a screen or select a non-glossy white wall onto which
you can project your image.
Carrying The LCD Projector Ensure that the power cord and
any other cables connecting to video sources are disconnected
before moving the projector. When moving the projector or
when it is not in use, cover the lens with the lens cap.
Selecting A  Location  The further your LCD projector is from
the screen or wall, the larger the image. The minimum size the
image can be is approximately 0.5 m (20) measured diago-
nally when the projector is roughly 1.0 m from the wall or
screen. The largest the image can be is 7.6 m (300) when the
projector is about 12.0 m from the wall or screen.

							E-18
Using A Tabletop Or Cart
1. Place your LCD projector on a flat level surface at the
optimal distance from the screen or wall so you realize the
size image you want. (Avoid having bright room lighting or
sun light directly on the screen or wall where youll be
projecting the image.)
2. Connect the power cable, remove the lens cap and turn the
projector on. (If no input signal is available, the projector will
display a background image.)
3. Ensure that the projector is centered to the screen.
4. Move the projector left or right to center the image horizon-
tally on the screen. (A)
5. To center the image vertically (B), lift the front edge of the
projector and press the buttons on the front of the projector,
just above the feet, to release the one-touch tilt feet. (There is
approximately 10.5û of up and down adjustment for the front
of the projector. )
6. If a trapezoidal distortion appears on the screen, use the
Focus and CTL buttons on the remote control or select the
Keystone from the Settings Menu under the Main menu.
Note: The keystone function is not available if no input signal
is present.
If necessary, adjust the front or rear feet so that the lens
surface is parallel to the screen. If you use the projector with
the screen tilted, the picture will be distorted. Each of the rear
feet height can be changed up to 5mm (0.2Ó).
7. Increase or reduce the size of the projected image by press-
ing the Zoom (+) or (Ð) buttons on the remote control or
top of the cabinet. (The zoom buttons are not available on
GT2000R.)
8. Adjust the focus by pressing the Focus (+) or (-) buttons on
the remote control or top of the cabinet.
(The focus buttons are not available on GT2000R. Use the
Focus/Floating lock knob and Focus/Floating ring to adjust
the focus on GT2000R. See below.)
To adjust the focus on GT2000R
1. Make sure that the focus lock knob and the floating lock knob
are tightened.
2. Adjust the focus at the center of the screen.
1) Loosen the focus lock knob, then grasp the focus ring and
rotate it.
2) Rotate the focus ring until the best center focus is ob-
tained, and tighten the focus lock knob to lock it.
3. Adjust the focus at the edges of the screen.
1) Loosen the floating lock knob, then grasp the floating ring
and rotate it.
2) Rotate the floating ring until the best edge focus is ob-
tained, and tighten the floating lock knob to lock it.
4. Select the Projection and choose Rear-front or Rear
ceiling to project an image from the rear.
