TROUBLESHOOTING

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 InFocus at www.infocus.com/support.

Often the problem is traced to something as simple as a loose connection. Check the following before

proceeding to 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 standby 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.

Keep a record of the steps you take when troubleshooting. The information may be useful when call-

ing Technical Support and obtaining service.
