Power-Up Error Codes

When the radio is turned on (power-up), the radio performs self-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's display. For non-display radios, the problem will be presented at
power-up by a single, low-frequency tone. The radio should be sent to the depot if cycling power and
reprogramming the code plug do not solve the problem. The presence of an error 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;
non-fatal errors will not. Use
displays.
