3-1. TROUBLESHOOTING GUIDELINES
The simple and rugged construction of ANTENNA GROUP OE-303/GRC reduces troubleshooting and
maintenance procedures.
The following table covers the troubleshooting steps you should take if there is a communications failure. If
your trouble cannot be corrected, notify C-E ORG MAINTENANCE.
The table does not cover troubleshooting the radio set. Before troubleshooting the antenna, make sure that
the radio is not the cause of the trouble by using the radio set troubleshooting guidance in the Radio Set
Technical Manual.
