Radio-Level Troubleshooting

Introduction to
This Section
This section of the manual contains troubleshooting charts and error codes that will help
you to isolate problems. Level one troubleshooting will support only radio alignment,
programming, battery replacement, and knob replacement. If the radio needs further
troubleshooting, it must be sent to the depot.
Board-level, component-level, and service information can be found in the ASTRO Digital
XTS 2500 Portable Radios Detailed Service Manual, Motorola publication number
68P81094C10.
Power-Up Error
Codes
When the radio is turned on (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’s display. For non-display radios, the problem is
indicated at power-up by a single, low-frequency tone. If cycling power and code plug
reprogramming do not fix the error, the radio should be sent to the depot for repair. 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. Table 23. lists their descriptions and suggested
corrective action.
