Troubleshooting
Incorrect operations are often mistaken for trouble and malfunctions. If you think that there is
something wrong with this component, check the points below. Sometimes the trouble may lie in
another component. Investigate the other components and electrical appliances being used. If the
trouble cannot be rectified even after exercising the checks listed below, ask your nearest Pioneer
authorized service center or your dealer to carry out repair work.
• If the system does not operate normally due to external effects such as static electricity,
disconnect the plug from the outlet and insert again to return to normal operating conditions.
