9-4 Basic Troubleshooting: Operational Error Codes
9.4 Operational Error Codes
During radio operation, the radio performs dynamic tests to determine if the radio is working properly. 
Problems detected during these tests are presented as error codes on the radio’s display. The 
presence of an error code should prompt a user that a problem exists and that a service technician 
should be contacted. Use the following tables to aid in understanding particular operational error 
codes.
