APPENDIX C - MINIMUM PERFORMANCE CHECK
C-1
GENERAL
This section contains a quick, qualitative, step-by-step check for
assessing the performance of the FM/AM-1200S/A.
This check should be
used when the operating condition of the set is in question.
The check
contained in this section is performed using the FM/AM-1200S/A front
panel controls and does not require the removal of the exterior case.
This check can be performed within 4 to 6 minutes, while the set is
operating on its own internal battery power.
Only a two foot length of
5011 coaxial cable (with BNC connectors on each end) is required as
accessory equipment to perform this check.
!NOTE\
If a determination is made that the FM/AM-
1200S/A is not performing properly as a result
of this performance check, the operator/
technician should perform a thorough laboratory
or bench check before taking any corrective
maintenance action.
