Common Problems and Solutions
These guidelines provide tips to deal with problems you may encounter while using the
Qumi. If the problem remains unresolved, contact your dealer for assistance.
The problem sometimes can be as simple as a wire that is not completely connected.
Review the following possible issues before proceeding to the problem-specific solutions.
• Use another electrical device to confirm that the electrical outlet is properly working.
• Make sure that the Qumi is turned on.
• Make sure all connections are securely connected.
• Make sure that the connected device is turned on.
• Make sure that the connected PC is not in suspend or sleep mode.
• Make sure the connected notebook computer is properly configured for an external
display.
Tips for Troubleshooting
In each problem-specific section, perform the steps in the order suggested. Doing so may
help solve the problem more quickly.
In order to avoid replacing non-defective parts, try to find and isolate the problem.
For example, if you replace batteries and the problem remains, put the original batteries
back and move to the next step.
Keep a record of the steps you take when troubleshooting. The information may be useful
for reference when calling technical support or for bringing the Qumi to service personnel.
