Common Problems and Solutions

These guidelines provide tips to deal with problems you may encounter while using the projector. If the problem remains unsolved, contact your dealer for assistance.

Often after time spent troubleshooting, the problem is traced to something as simple as a loose con- nection. Check the following before proceeding to the problem-specific solutions.

•Use another electrical device to confirm that the electrical outlet is working.

•Ensure the projector is turned on.

•Ensure all connections are securely attached.

•Ensure the attached device is turned on.

•Ensure a connected PC is not in stand-by mode.

•Ensure a connected notebook computer is configured for an external display. (This is usually done by pressing a Fn-key combination on the notebook. Go to www.infocus.com/support and the Learn tab to review the Laptop Activation chart.)

Tips for Troubleshooting

In each problem-specific section, try the steps in the order suggested. This may help you to solve the problem more quickly.

Try to pinpoint the problem and avoid replacing non-defective parts.

For example, if you replace batteries and the problem remains, put the original batteries back and go to the next step.
