Adjusting the Power Settings
For greater ease of use, you should keep the computer on all the time. However, to help preserve
the computer's hard drive(s), and the life of the projector lamp, you should also set the monitor and
hard drive(s) to turn off automatically after a specified period of inactivity. You can do this by
configuring the Windows operating system Power Management Feature. If you do keep the
computer on all the time, reboot the computer occasionally to reload the operating system.
NOTE: You may prefer to shut the computer down at the end of the day. In this case, power up the
computer every day.
On shipment, the projector is configured to shut down five minutes after no new input signal is
received, so if the monitor shuts off after a period of inactivity, so will the projector lamp. However,
if anyone changes the projector settings, the projector settings we've configured for you may be
inadvertently toggled off. If this happens, follow the procedure on page 41 to restore the optimal
settings.
If both the computer and projector are configured properly, a five-minute projector shutdown period
follows the designated period of computer inactivity. During the shutdown period, the interactive
whiteboard screen turns blue. If you change your mind and want to use the system again, you can
restore the computer display by simply touching the screen. At the end of the shutdown period, the
projector lamp shuts down completely and the screen turns black.
You should avoid using a screen saver, regardless of whether you power the computer down daily
or not. The benefit of a screen saver – to avoid image burn-in, either on monitors or plasma
displays – has no bearing on a projected system.
NOTE: You can't adjust the power settings on Windows NT 4.0 systems, so the computer must be
left on with full power, or shut down at the end of the day and started up again.
To adjust the computer's default power settings
1. Click the Start button on the Windows taskbar, point to Settings and select Control Panel.
2. Double-click Display and click the Screen Saver tab.
3. Under Energy saving features of monitor, click the Settings button.
The Power Management Properties dialog box appears.
4. Select After 1 hour from the Turn off monitor list.
NOTE: This is a recommended setting. You can select any duration you want.
5. In the Turn off hard disks list, select the period of inactivity that must elapse before hard disk
shutdown.
NOTE: For the above step, we recommend that you select After 2 hours. This extended time
period ensures that guest laptop presenters − or participants in lengthy meetings characterized
by large gaps in activity − do not experience an unexpected hard disk shutdown.
6. Click the Apply button and then click OK.
When the system reaches the period of inactivity specified in step 4, the computer stops
sending an RGB signal. If no other source is active, the projector goes into a five-minute
shutdown mode, during which time the screen turns blue. After five minutes, the projector
shuts down completely and the screen turns black.
NOTE: To immediately restore the input signal from the computer during this five-minute
projector shutdown period, touch the screen (or press a keyboard key). This function is
especially handy when you're a passive participant in a lengthy data conference.
