NOTE: We recommend that you select a time value of 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 computer
shutdown.
6 Click the Apply button and then click OK.
When the period of inactivity specified in step 4 is reached, the RGB input signal from
the computer ceases. If no other source is active, the projector itself will go into a five-
minute shutdown mode, during which time the screen will turn blue. After five minutes
have elapsed, the projector will shut down completely and the screen will turn black.
During this five-minute projector shutdown period, touching the screen (or pressing a
keyboard key) will immediately restore the input signal from the computer. This method
of quickly restoring the computer's video signal is especially handy when you're a
passive participant in a lengthy data conference.
Adjusting the Projected Image
You may need to make a few final adjustments to the projector to ensure a focused image
that fits on the interactive whiteboard screen. While making these adjustments, check both
the reflection in the small mirror and the actual image on the screen. For an optimal image,
the reflection must be in the center of the small mirror and each side must be symmetrical.
To adjust roll
Using the wrench provided in the Accessory Kit, loosen the Locking Screw below the projector.
Tighten and loosen the large, round knob beside the Locking Screw until the image is correctly
rotated. Finally, tighten the Locking Screw with the wrench until it's snug against the projector
plate, and then give the screw a gentle quarter-turn.
WARNING: If you tighten the security screw too much, you run the risk of distorting the
projector plate.
To adjust the image laterally
Loosen the two large, black T-knobs located below the projector plate. Slide the projector
plate laterally, and then tighten the two T-knobs.
