Remote Control Notes

• Use the remote control within a distance of about 7m (23feet) and at an angle of 30˚ 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 control 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.

INSTALLATION2

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.

Attaching the lens cap to the lens hood with the supplied string and rivet. (GT2000 only)

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 diagonally 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.

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 you'll 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 horizontally 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 10.5˚ 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 (0.2”).

7. Increase or reduce the size of the projected image by press-

ing the "Zoom" (+) or (–) buttons on the remote control or top of the cabinet. (The zoom buttons are not available on GT2000R.)

8. Adjust the f ocus 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 obtained, 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 obtained, 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.

Unit

address

* Command specification code: This code specifies whether the

command is a single control command or a multiple control command. A single control command (C0H) is valid for only the projector specified by the unit address. A multiple control command (C1H) is valid for all projectors which receive the command, regardless of the unit address. Note that only projectors in agreement with the unit address will return an ACK.

* Unit address: This code specifies the ID of the projector (0-64).

You can select the [Settings Menu]->[Projector ID] under the main menu and specify the ID of projector. For a single projector, the ID should be set at 0.

Command Communications Sequence

When a command sent from the personal computer has been correctly received by the projector, an "ACK" is returned for the command. When the command has not been received correctly, a "Receive Error" is sent back. An invalid command will cause a "Command Error".

Note: When an"ACK" from the projector is not confirmed and the next command is received by the projector, an error in communication can result.
