COMMUNICATIONS SYSTEM

Procedural Steps:

1. If one or more of the control boxes becomes inoperable but the AM-1780 is still

operational, install TA-312 or TA-1 field telephones at the station(s) where the bad

control boxes are located and run field telephone wire back to the AM-1780. The WD-

l/TT should be hooked upon the “line” jacks of the AM-1780.

2.

If the AM-1780 is not operational, replace the entire intercom system with TA-312

or TA-1 telephones and field telephone wire.

Run the wire in a circle throughout the

vehicle so that all telephones are connected to the same wire.

3.

Record the BDAR action taken.

When the mission is completed, as soon as

practicable, repair vehicle using standard maintenance procedures.
