Chapter 6 Troubleshooting

There are simple ways to diagnose and resolve problems. In many cases, the issue can be resolved within a few
minutes, avoiding the inconvenience and loss of productivity that results from having to return the receiver for
repair. This section discusses troubleshooting issues and includes cross-references to other sections of the
manual that may help resolve problems.
If unsure of the symptoms or if the symptoms do not match any of those listed, use the RXSTATUS log to check
the receiver status and error words. See Examining the RXSTATUS Log on the next page.
