This Component Maintenance Manual (CMM) documents the operation of and suggested
maintenance for the Model FA2100 Cockpit Voice Recorder, herein after referred to as the
FA2100CVR.
The FA2100CVR meets the performance requirements of ED-56A, while complying with
the interface requirements of ARINC 557/757 cockpit voice input data including Rotor
Speed and GMT interfaces. The only exception is P/N: 2100

voice and area microphone channels are lowpass filtered, sampled, digitized, com-
pressed, and stored in solid-state, crash protected memory. This CMM covers both the
