PARTS OR ASSEMBLIES.
2. Content Data
A. How to Use This Manual
(1) The instructions in this manual give the data necessary to do all recommended
maintenance functions to put the CAS-100 Collision Avoidance System (CAS-100) in
serviceable condition. Standard maintenance procedures that technicians are thought to
know are not given in this manual.
(2) Refer to the table of contents to see which subheadings are included in this manual. The
table of contents identifies those subheadings that are not applicable or require no
special instructions.
MAINTENANCE MANUAL
CAS-100 COLLISION AVOIDANCE SYSTEM
(3) We recommend that the tests in TESTING AND FAULT ISOLATION be done before the
unit is disassembled. These tests can tell the condition of the CAS-100 or most probable
cause of any malfunction. Should any malfunction occur, repair as necessary.
