EVALUATE THE OPERATION OF
INTERCOMMUNICATIONS SET AN/VIC-1(V)
Upon completion of this lesson, you will be able to accurately evaluate the performance of an
intercommunication set AN/VIC-1(V) and accurately record the results of the evaluation on a DA Form
2404 (Equipment Inspection Maintenance Worksheet).
This lesson is based on performance measures outlined in STP 11-31V12, dated May 1987; information
in TM 11-5830-340-12, Chapters 1, 2, and 4, dated January 1986; and GTA 11-3-49, dated December
1986. However, development and progress render the text continually subject to change; therefore, base
your examination answers on material presented in this subcourse rather than on individual or unit
An operational check (op check) is normally done with the
intercommunication set AN/VIC-1(V) installed in a vehicle. As a minimum, the op check is done as
part of the PMCS. At the discretion of the maintenance supervisor, the op check could be done more
often than the scheduled PMCS. After every repair of an item of equipment, the portion of the op check
that applies to that item of equipment should be done again to ensure that the fault found has been
corrected and that no other faults exist.
INTERCOMMUNICATION SET AN/VIC-1(V).
a. The intercommunication set AN/VIC-1(V) provides voice communications between crew
members and also allows crew members to control and use the radio set that is installed with some
b. The intercom may be installed in various types of combat (tracked) vehicles. The intercom is
part of the installed electronic installation harness of combat vehicles and part of the installation kit
when installed in tactical (wheeled) vehicles.
c. Accessory kits for the intercom consist of items such as audio accessories, installation
instructions, technical manuals, and other miscellaneous parts. Accessory kits are readily installed in
and removed from combat (tracked) vehicles only.
d. The basic components of the intercom set are the amplifier, audio frequency AM-1780
(which is the heart of the intercom); the crew member control box C-2298; the crew member
interconnect cable CX-4723; and a power cable CX-4720 or CX-13089.
e. See Figure 1. The intercom set AN/VIC-1(V) is a highly versatile piece of equipment that
can be used alone or with FM radios.
