This paragraph provides the unit maintainer with a general use schematic (Short Range Single Radio Mount)
plus 12 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.
