Some laptop computers deactivate their screens when you connect a secondary display. Refer to

your computer’s manual for details on reactivating the computer's display screen.

Unaligned projected image

Alignment errors occur when the projected image isn’t perpendicular to the screen. Alignment

errors can occur when if the interactive whiteboard system is mounted on an uneven surface or a

wall that has obstructions, or if the projector is swiveled too far from the interactive whiteboard’s

vertical center.

Adjust the projected image using the instructions in the included

SMART Board 800ix3 interactive

whiteboard system installation guide (

The projector image can slip if the projector is moved often or installed in a location prone to

vibration, such as next to a heavy door. Follow these precautions to help prevent the image from

becoming unaligned:

Make sure that the installation wall is plumb and square and doesn’t move or vibrate

excessively.

Make sure that there are no obstructions behind the projector’s wall-mounting bracket, and

that the bracket is firmly secured to the wall according to the installation instructions.

Adjust the projected image. See the included

Resolving audio issues

The projector includes an integrated speaker. You can also connect an external audio system to

the audio output connector in the projector’s connection panel. If sound isn’t coming from either

the internal speaker or the external audio system, perform the following procedures.

NOTE

You might need to configure your computer to pass audio through HDMI if it isn’t configured

automatically.

To resolve audio issues

1. Ensure that the speakers’ or audio system’s cables are properly connected to the audio

output plug on the projector’s connection panel.
