Page 161: Chapter 5 Troubleshooting Procedures
Chapter 5 Troubleshooting Procedures Introduction The purpose of this chapter is to aid in troubleshooting problems with the ASTRO XTS 2500/ XTS 2500 digital portable radio. It is intended to have enough detail to localize the malfunctioning circuit and isolate the defective component.
Page 162: Standard Bias Table
Troubleshooting Procedures: Standard Bias Table In most situations, the problem circuit may be identified using a multimeter, RF millivoltmeter, oscilloscope (preferably with 100 MHz bandwidth or more), and a spectrum analyzer. When checking a transistor or module, either in or out of circuit, do not use an ohmmeter having more than 1.5 volts dc appearing across the test leads, or use an ohms scale of less than x100.
Page 163: Power-Up Self-Check Errors
Troubleshooting Procedures: Power-Up Self-Check Errors Power-Up Self-Check Errors Each time the radio is turned on, the microcontroller unit (MCU) and the digital signal processor (DSP) perform some internal diagnostics. These diagnostics consist of checking the programmable devices such as the FLASH ROMs, internal and external EEPROMs, and SRAM devices. At the end of the power-up self-check routines, if an error exists, the appropriate error codes may be read using the Customer Programming Software (CPS) from the RS232/USB bus on the universal (side) connector.
Page 164: Operational Error Codes
Troubleshooting Procedures: Operational Error Codes Operational Error Codes During radio operation, the radio performs dynamic tests to determine if the radio is working properly. Problems detected during these tests are presented as error codes on the radio’s display. The presence of an error code should prompt a user that a problem exists and that a service technician should be contacted.

If this does not fix the problem, then the radio should be sent to the depot for re-flashing of the DSP code. Continued failure requires examination and/or replacement of the SRAM (U804).
