Error Code Displays

Power-up Display Codes

At power-up, the radio performs cursory tests to determine if its basic electronics and software are in
working order. Problems detected during these tests are presented as error codes on the radio
display. The presence of an error code should prompt the user that a problem exists and that a
service technician should be contacted.
Self-test errors are classified as either fatal or non-fatal. Fatal errors will inhibit user operation, while
non-fatal errors will not. Use
displays.
FAILURE TYPE OF
DISPLAY FAILURE
FAIL 01/81 FATAL
FAIL 01/82 FATAL
ERROR 01/02 NON-FATAL
FAIL 01/84 FATAL
FAIL 01/88 FATAL
FAIL 01/90 FATAL
FAIL 01/92 FATAL
FAIL 01/93 NON-FATAL
FAIL 01/94 FATAL
FAIL 01/98 FATAL
ERROR 01/12 NON-FATAL
ERROR 09/10 FATAL
NOTE: 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.
