The Proxima LX2 (referred to as "projector" for the remainder of this document) is designed with the most advanced technology for portability, durability, and eash of use. The projector utilizes built-in multimedia features, a palette of 16.77 million colors, and matrix liquid crystal display (LCD) technology. This projector is compatible with many different types of personal computers and video devices including IBM-compatible, Apple Macintosh and PowerBook computers at video resolutions up to 1280 x 1024 and VCR, Laserdisc and DVD players, video camera or any other device using any of the world wide video standards. The picture image resolution is 1024 x 768. Screen resolutions between 1024 x 768 and 1280 x 1024 are compressed to 1024 x 768. This projector cannot display resolutions above 1280 x 1024. This projector automatically tunes to most personal computers currently distributed by simply connecting.

This document assumes the reader is familiar with the information presented in the "Display Systems General Information" document.

The projector has two VGA connectors (see Figure 1). The top connector "computer IN" should be connected to the computer external video port. The bottom connector "monitor OUT" won't normally be used but could be connected to an external video monitor.

If you intend to use the remote control's mouse function, the "PC control" port (see Figure 1) should be connected to the computer mouse port. There are three different PC control cables provided: PS/2, Serial and ADB. Which cable you use depends on your computer. If you have a Macintosh computer you will use the ADB cable. If you have a PC you can use either the PS/2 or Serial cable. If your PC is configured to use an external mouse you should choose the cable that matches the type of mouse you use. If you are using an external keyboard with the PC and the PC has a combo PS/2-Keyboard port, you will have to use the serial mouse cable. Whichever cable you choose, you will need to make sure the computer is configured and has the necessary software drivers installed to use the matching external mouse port.

Figure 1

The PS/2 mouse cable has a round PS/2 port plug on one end and the round PC control port plug on the other end. Close examination will show the two plugs are different and cannot be interchanged. The cable end labeled "PS/2" plugs into the computer PS/2 mouse port. The Serial mouse cable has a nine pin serial port connector on one end and the round PC control port plug on the other end. The cable end labeled "Serial" plugs into a computer serial port (also known as a COM port). The ADB mouse cable has a round ADB port plug on one end and the round PC control port plug on the other end. Close examination will show the two plugs are different and cannot be interchanged. The cable end labeled "ADB" plugs into the Macintosh ADB port.

If your presentation includes video from an external video device such as a VCR, Laserdisc or DVD Player, video camera or other, you will need to connect the Audio/Video or S-VIDEO cables. The projector can switch back and forth from computer to video display.

The audio capabilities of the projector are very limited. For this reason we discourage using the built in monaural speaker.

The projector has adjustable feet at the front corners. To release the feet, lift the front of the projector and pull the feet latches on both sides of the projector. Release the feet lock latches to lock the adjustable feet. Screw the feet in or out to fine tune their adjustment.

The projector can focus as close as 4.6 feet and as far away as 35.4 feet. The focusing distance will determine where you will have to set up the projector. The size of the projection surface will also be a determining factor. Move the projector closer to the projection surface for a smaller picture and move the projector farther from the projection surface for a larger picture.

The projector controls and indicators are shown in Figure 2. The red "lamp" indicator shines bright when the projector is in stand-by mode and shines dim when the projector is turned on. The green "ready" indicator comes on when the projector is ready to be turned on. The red "warning temp." indicator flashes when the internal projector temperature is too high. The yellow "lamp replace" indicator comes on when the projection lamp is near needing to be replaced.

Figure 2

Confirm the ready indicator is on then press the "power" button to turn on the projector. You will see the preparation display and observe a 30 second countdown while the projector warms up. To turn off the projector press the power button. You will see a "Power off?" message on the projector display. Press the power button again to confirm you want to turn off the projector. The lamp indicator will shine bright and the ready indicator will turn off. The cooling fan will run for 90 seconds after the projector is turned off. During this cooling period the projector cannot be turned on. When the cooling period finishes the ready indicator comes on. At this time the projector can be turned on or you can safely unplug the power cable. Allow the projector to cool as long as possible before packing or transporting.

The "zoom" buttons increase or decrease the size of the image on the projection surface. Moving the projector closer to or farther away from the projection surface should be used as a gross adjustment to fit the projection image on the projection surface. Use the zoom feature to fine tune the size of the projection image on the projection surface. Adjust the focus with the "focus" buttons. If you're using the projectors built-in monaural speaker the "volume" buttons will increase or decrease the volume. The "mode" button switches between the computer or video input source. The "auto image" button can be used to automatically adjust the projector settings that control the projection image. If a portion of the display is not being shown or the projection image appears jaggedy or grainy the auto image button may improve the projection image. The "normal" button returns the projector settings the factory defaults. Try the normal button if the projector seems to be display abnormally or not at all.

The "menu", "select", and "point" buttons are used with the on-screen menu. Refer to the projector user's guide for more information about the on-screen menu. The select and point buttons are also used in digital zoom mode. Refer to the projector user's guide for more information about the digital zoom mode.

The remote control provides easy access to the most commonly used features. All the features found on the remote control, with the exception of mouse control, are available either with buttons on the projector or by accessing the projector on-screen menu.

Two functions that are only accessible through the projector on-screen menu, "d.zoom" (digital zoom) and "keystone", are easily accessed with buttons on the remote control (See Figure 4). Digital zoom feature allows the projector display to be magnified or reduced. The point button can be used to pan the projector display when using the digital zoom function. The normal button exits the digital zoom mode. You should experiment with the digital zoom mode before using it during a live presentation. It can be difficult to control without practice. The keystone feature adjusts the video display to cancel out vertical distortion (display is wider at the top or bottom of the projector display).

The projector remote control has a power switch on its left side (see Figure 3a). The power switch prevents battery drain when the remote control is put into a carrying case and something inadvertently presses one of its buttons. Activating the built-in laser pointer is a good method of determining if the batteries are OK. There is a remote receiver window at the front and rear of the projector (see Figure 3b). Sometimes it is possible to bounce the remote control signal off the projection surface and into the receiver window at the front of the projector.

The projector PC control port can be connected to a notebook computer mouse port. This allows the projector remote control to function as a computer mouse. The round Point Button (see Figure 4) functions similarly to a joystick. Press upwards on the button to move the mouse pointer up, press downwards to move the mouse pointer down and so on. Below the Point Button are two mouse buttons (see Figure 4) for left (Select Button) and right (Right Click Button) mouse clicks. You can also depress the Point Button for a left mouse click. This is a very convenient way to advance to the next slide in a presentation.
