Power-Up Self-Check Errors
Each time the radio is turned on, the MCU and DSP perform a series of internal diagnostics. These
diagnostics consist of checking such programmable devices as the FLASH ROMs, the EEPROM,
and SRAM devices.
Problems detected during the power-up self-check routines are presented as error codes on the
radio’s display. For non-display radios, the problem is presented at power up by a single, low-
frequency tone.
Table 4-4
lists possible error codes, a description of each error code, and a
recommended corrective action.
