This section of the manual contains troubleshooting charts and error codes
that will help you to isolate a problem. 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- and component-level and service information can be found in the
"ASTRO Digital XTS 3500 Portable Radios Detailed Service Manual," Motorola
publication number 68P81089C81.
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 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 15 to aid in understanding
particular power-up error code displays.
