Requirements
Instructional ·The instructor prepares for this lesson by studying this instructor's guide and the reference materials.
Guidance
·The instructor should ensure the students train on a BFV-ODS to reinforce their newly-learned skills.
Safety Soldiers should exercise extreme caution to prevent noise-induced hearing loss when listening to the
Requirements VIS radio. Prolonged exposure to the full-on volume control setting requires the use of a hearing
protection device in each ear. The volume control in the green area is safe; the headset receiver should
be adjusted to the minimum level required for operation.

SECTION II. INTRODUCTION
Motivation Use the following points to motivate the students:
·The Vehicular Intercommunications System (VIS) is a reliable and modern system for combat vehicles.
·The VIS uses digital transmission of audio signals to enhance speech quality and intelligibility.
·The students have been introduced to some of the BFV-ODS improvements; during this lesson they will learn to operate the VIS. While not an ODS improvement, the VIS is introduced to the Bradley with the ODS version.
·Knowing the VIS components and their functions will permit the students to use the VIS effectively.

GOOD MORNING. I AM _______________________________________.
AS YOU HAVE ALREADY LEARNED, SEVERAL IMPROVEMENTS HAVE BEEN MADE TO THE BRADLEY FIGHTING VEHICLE AS A RESULT OF LESSONS LEARNED DURING OPERATION DESERT STORM. ANOTHER IMPROVEMENT INTRODUCED WITH THE BRADLEY ODS IS AN IMPROVED COMMUNICATIONS CAPABILITY KNOWN AS THE VEHICULAR INTERCOMMUNICATIONS SYSTEM, OR "VIS."
THE VIS IS A MODERN, RELIABLE COMMUNICATIONS SYSTEM FOR GROUND COMBAT VEHICLES. ITS STATE-OF-THE-ART DESIGN USES DIGITAL TRANSMISSION OF AUDIO SIGNALS AMONG CREW STATIONS. DIGITAL AUDIO DATA SIGNIFICANTLY ENHANCE SPEECH QUALITY AND
VGT VIS-1
Instructional INTELLIGIBILITY. THE HEADSETS INCORPORATE ACTIVE NOISE REDUCTION
