Chapter 8 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
