Troubleshooting: Operational Error Codes 8-3
8.4 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
Table 8-3 to aid in understanding particular operational error codes.
8.5 Receiver Troubleshooting
Table 8-4 lists the possible causes of, and corrections for, receiver problems.
