  Description of modification

  The CVR-120R system records 4 channels of audio. The channels are the pilot ICS, co-pilot ICS, area microphone and 3rd crew (jump seat) position ICS. The Universal Cockpit Voice Recorder consists of a CVR-120R recorder unit, 
  a cockpit control unit, an inertia switch, an area microphone, an audio mixing amplifier and three ELT circuit breakers. Also, the system includes an internal Recorder Independent Power Supply (RIPS). The RIPS powers the unit for approximately 10 minutes whenever the aircraft power is removed. 
  The CVR utilizes the Dukane Model DK120 underwater acoustic beacon which is attached to the recorder environmental shell for easy removal and 
  for easy viewing of the battery expiration date. For older aircraft intercom systems a summing amplifier is added to combine headphones and microphone signals for each channel.
