4-4 Test Mode and Error Codes
Self-test errors are classified as either fatal or non-fatal. Fatal errors will inhibit
user operation, while non-fatal errors will not. Use Table 4-1 to aid in
understanding particular power-up error code displays.

Table 4-1 Power Up Display Codes
Due to the nature of fatal ROM & RAM errors, it may not be possible to present
an error code on the display. In these cases the radio will attempt to display
the appropriate error code, generate an illegal mode tone for one second and
then reset its microcontroller.
During operation, the radio performs dynamic tests to determine if it is
working properly. Problems detected during these tests are presented as error
codes on the radio 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 4-2 to aid in understanding particular operational error code displays.
