It’s all right to move Presenter 1280 once the cables are attached, but do not extend the cables so much that you stress or loosen the connection. 8. If Presenter 1280 is not already on, turn it on or restart it in one of the following ways: If you have a CRT monitor attached, open the Monitor Panel.
This causes overheating, and will damage the display. 11. Place Presenter 1280 face down on the overhead projector so that only the back of the Presenter is visible, and slide it under the two clips on the projector to secure it.
RCA plug at each end. Choose the cable with the connector that matches the speaker connector on the Presenter 1280 base. The RCA plug on either cable always connects to the overhead projector. See Figure 1-12 for the speaker connector locations.
Chapter 1: Setting Up and Using the Presenter 1280 Monitor 1. Follow these steps to adjust the volume: From the Desktop menu in the Toolchest, choose “Audio Control.” The Audio Panel shown in Figure 1-13 appears. Adjust the volume by moving the sliders.
Presenter’s backlight panel, as shown in Figure 1-14. Caution: Make sure you turn the projector off before replacing the backlight panel. Leaving the Presenter 1280 with the backlight panel attached on an overhead projector that is on causes overheating, and can permanently damage the display.
Chapter 1: Setting Up and Using the Presenter 1280 Monitor 3. Rotate the base up and slide Presenter 1280 out from under the two projector clips. Presenter 1280 is now ready to be used as a desktop monitor. Adjusting the Brightness You can control the brightness on Presenter 1280 with the Monitor Panel.
2. Click the 24-bit mode button. Adjusting the Volume and Tone of the Speakers The Presenter 1280 stereo speakers and the monaural speaker on the Dukane 28A682 overhead projector are designed to work with the standard speaker on your workstation.

VCCI Class 1 Statement for Japan Electrostatic Discharge Silicon Graphics designs and tests its products to be immune to effects of electrostatic discharge (ESD). ESD is a source of electromagnetic interference and can cause problems ranging from data errors and lockups to permanent component damage.
Silicon Graphics have shielded cables. Shielded cables reduce the possibility of interference with radio, television, and other devices. If you use any cables that are not from Silicon Graphics, make sure they are shielded. Telephone cables do not need to be shielded.
About Liquid Crystal Display (LCD) Technology Display The key component in the Presenter 1280 is the active-matrix display module. It is composed of twisted nematic liquid crystal material, sandwiched between two sheets of glass, activated by electronic switches deposited on the inner surface of the glass. The electronic switches vary the voltage applied to the liquid crystal and thus change its transparency.
CRT. A third difference is the lack of flicker on the Presenter 1280’s flat panel. CRTs flicker because the electron beam can be in only one place at a time. Thus each pixel on a CRT is being driven only about a millionth of the time.
Quality The resolution of the Presenter 1280 monitor is 1280 x 1024 pixels. Therefore there are 1280 x RGB x 1024, or 3,932,160 sub-pixels in your display—all in an area equivalent to 2.5 times that of a 6-inch silicon wafer. Current technology is not capable of producing a 100% defect-free active matrix display at reasonable costs, although yields are improving steadily.
