TROUBLESHOOTING
6.1 INTRODUCTION
6.1.1 General
This chapter provides troubleshooting data necessary for fault isolation to the LRU level.
6.1.2 Scope of this Chapter
See Figure 6-1. The procedures presented in this chapter assume that a Level I fault has led the maintainer to
suspect a fault with the RF-5800H 125-Watt Communication System. The maintainer begins the troubleshooting
process by using the maintenance turn-on procedure to find a fault indication that identifies the faulty LRU. If
there is a non-BIT fault, the maintainer will use the non-BIT troubleshooting procedures. If there is a BIT fault,
the maintainer will use the BIT troubleshooting procedures. TAPs are provided to help the maintainer isolate
faults using procedures other than simple unit swapping. When the problem is found and corrected, the radio
system is returned to operational readiness.
