Normal Operation
The radio antenna receives AM and FM radio waves. The radio waves are sent to the audio unit through the radio antenna lead-in cable. The radio suppression equipment reduces engine ignition and electrical systems interference transmitted through the speakers.

When installing any new radio suppression equipment components, make sure that a good contact is made at all connections. Remove any paint or dirt from between a component and its ground. Tighten all connectors and screws securely according to torque specifications.

Possible Causes
- antenna
- antenna cable(s)
- radio frequency interference suppression equipment
- audio unit
