Basic Troubleshooting

Introduction
to This Section
Power-Up
Error Codes
This section of the manual contains troubleshooting charts and error codes
that will help you to isolate a problem. Level one and two troubleshooting will
support only radio alignment, programming, battery replacement, and knob
replacement, and circuit board replacement.
Component-level service information can be found in the "ASTRO Digital
XTS 5000 Portable Radios Detailed Service Manual," Motorola publication
number 68P81094C31.
When the radio is turned on (power-up), the radio performs self-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 will be presented at power-up by a single,
low-frequency tone. The radio should be sent to the depot if cycling power
and reprogramming the code plug do not solve the problem. 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. Use Table 17 on page 64 to aid in
understanding particular power-up error code displays.
