Power Up Self-Test

Error Codes - Privacy Plus
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, non-fatal errors will not. Use Table 6-2: Power-up Display Codes to
aid in understanding particular power-up error code displays.

NOTE: Due to the nature of fatal ROM and RAM error, 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.
