Chapter 9 Basic Troubleshooting

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 circuit board replacement.

Component-level service information can be found in the “ASTRO APX 3000 Portable Radios

Detailed Service Manual,” Motorola publication number 68012007045.

9.1 Power-Up Error Codes

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 9-1 to aid in understanding particular power-up error code

displays.
