cause of a problem. The event log number, date and time of the event, and a
description of the event are shown.
Press ENTER to review the event log. The most recent log is shown first. Use the

PROBLEM SOLVING
Most radio system problems are due to the failure of components
outside
of the transceiver—such as a poor or broken feedline or antenna connec-
tion. This section will help you determine whether the problem is out-
side or inside the radio and, if in the radio, how to restore operation as
quickly as possible.
GE MDS does not recommend component-level repairs in the field.
However, you can replace the radio’s major assemblies without using
tools or test equipment.
Section 8.0,
REPLACING ASSEMBLIES,
beginning on Page 86
covers this in detail.
If you cannot solve a system problem with the information provided
here, technical assistance is also available from the factory. Refer to the
inside back cover of this guide for contact information.
NOTE:
Before starting any detailed troubleshooting, check the basic
requirements at both ends of the link: primary power, secure
cable connections, and proper antenna heading. In many cases,
one of these cause poor operation or a complete loss of link
service.
