This paragraph provides the unit maintainer with four general use schematics (Short Range FIT-A; Short Range
FIT-B; Long Range RT-A; and Long Range RT-B) plus 22 Troubleshooting Charts. The unit maintainer is
directed to one or more specific Troubleshooting Chart from the Operational Check. Use of Troubleshooting
Charts prior to application of the Operational Check, represents poor use of unit maintainer time, can result in
false pulls, and is strongly discouraged.
After application of the Operational Check and one or more Troubleshooting Charts, if required, the unit
maintainer will perform the prescribed LRU replacement or repair. To ensure that the system is completely
operational following such maintenance action, the unit maintainer again applies the complete Operational
Check. If the system then passes all steps of the Operational Check, the system may be declared fully
operational and returned to service.
