GENERAL INFORMATION

1.1.

SCOPE

This technical manual contains instructions for troubleshooting and corrective maintenance for the

AN/VIC-3, Vehicular Intercommunication Set, commonly known as the Vehicular Intercommunication Set

(VIS), as well as a "Repair Parts and Special Tools List' Appendix listing the parts required to maintain the

equipment.

a. Type of manual: Unit Maintenance Manual (Including Repair Parts and Special Tools List).

b. Model Number and Equipment Name: The official nomenclature is the AN/VIC-3(V)

Intercommunication Set, Vehicular, with its common name being the Vehicular

Intercommunication Set (VIS). There are many current and future variations of this system

designed for specific vehicles and/or platforms, each with its own unique technical bulletin for

installation. Refer to Table 1 -1 (at the end of this section) for the VIS version, vehicle /platform

it's installed in, and the corresponding installation technical bulletin. These vehicle/platform

specific variations have meaning only to the installation team as the system loses its identity

when installed. Any vehicle/platform that has this system installed is referred to as having the VIS

or "VIC-3"(AN/VIC-3(V)).

Purpose of Equipment: The AN/VIC-3(V) is an intercommunication and radio-control system

designed for ground mobile combat vehicles. Digital audio enhances speech quality and

intelligibility. Headsets that incorporate active noise reduction (ANR) circuitry increase the

effectiveness of vehicle communications. They offer increased hearing protection in the noisy

environment of combat vehicles.

d. Equipment Components. The AN/VIC-3(V) or VIS is a variety of installation kits designed for

specific vehicles and/or platforms. The VIS is designed to replace the AN/VIC-1, in some cases

utilizing the existing mounting hardware and brackets used by the AN/VIC-1. Kits consist of the

following components, the type and quantity of which vary depending upon the specific vehicle

and/or platform: Line Replaceable Units (LRUs (Boxes)) (Figure 1-1); cables (highway, power,

alarm, etc.); headsets; brackets; and mounting hardware for securing LRUs and brackets. The

RPSTL (Appendix C) of this manual only identifies the mounting hardware that is removed and

replaced as part of the maintenance procedures associated with the VIS. If the bracket, and/or

mounting hardware used to secure it, need replacing, refer to the appropriate installation

technical bulletin, Table 1-1, to identify the correct Part Number (PN) / National Stock Number

(NSN).
