Troubleshooting is done on a faulty PA mount. The steps to determine if a PA mount is faulty and how to
troubleshoot it are as follows:
a. When a PA mount is received from unit maintenance, inspect it for damage. Repair any damage
before proceeding with testing. See section IV if repairs are necessary.
b. Verify the symptom. Perform the operational check in paragraph 9-8. This will direct you to the correct
troubleshooting flowchart or identify the fault.
Troubleshoot the PA mount using the fIowchart. It will identify the defective module or component.
d. Replace the defective module or component.
Follow the procedures in section IV.
Verify the repair. Repeat the operational check in paragraph 9-8 that failed. If it passes, then continue
with the rest of the operational check. When the operational check is passed, the PA mount can be
returned for use.
