From a UNIX shell, enter:
apanel
2. Select "Presenter Audio" from the Options menu. The Presenter Audio
Panel shown in Figure 1-18 appears.
3. Click Mute on the Presenter Audio panel to mute the Presenter 1280
speakers. This also mutes the Dukane 28A682 overhead projector
speaker.
Do not disable your workstation's screen saver program when using
Presenter 1280. As with any CRT monitor, leaving an image up without a
screen saver for a long time may burn the image into the display.
If you are not planning to use Presenter 1280 for a few hours, it's a good idea
to turn it off. For further information, see "Turning Off the Presenter 1280
Monitor" on page 9. Leaving the display on for a long time shortens the life
of the display's backlight lamps.
