4-10 Troubleshooting Procedures: ASTRO Spectra Plus Procedures
4.2 ASTRO Spectra Plus Procedures
This section will aid you in troubleshooting a malfunctioning ASTRO Digital Spectra Plus radio. It is
intended to be detailed enough to localize the malfunctioning circuit and isolate the defective
component.
Please review Section 4.1.1 on page 4-1 and Section 4.1.2 on page 4-2 before continuing. Also, for
information on troubleshooting the RF board, refer to Section 4.1.4 on page 4-5.
4.2.1 ASTRO Spectra Plus Power-Up Self-Check Errors
Each time the radio is turned on the MCU and DSP perform some internal diagnostics. These
diagnostics consist of checking the programmable devices such as the FLASH ROMs and SRAM
devices. At the end of the power-up self-check routines any errors produced are recorded. If an error
exists, use the Customer Programming Software (CPS) from the RS232 bus on front and rear of the
radio to read the error code. Table 4-5 lists self-check error codes, describes the codes, and gives
the recommended corrective action.
Most of the ICs are static-sensitive devices. Do not attempt to
troubleshoot or disassemble a board without first referring to
the following Handling Precautions section.
