Troubleshooting

Refer to the Troubleshooting Chart as needed.

1. Most vehicle-radio interaction is avoided by following the Installation Guidelines outlined above.

2. If vehicle-radio interaction is evident following radio installation, the source of the problem should be determined prior to further vehicle/radio operation.

The EMC Troubleshooting Chart should help in determining the source of the vehicle-radio interaction.
