The Communication/Navigation/Surveillance (CNS) system includes the Audio Panel, communication radios, 

navigation radios, and Mode S transponder.  The System Overview Section provides a block diagram description 
of the Audio Panel and CNS system interconnection.

CNS operation in the Bell 407 is performed by the following Line Replaceable Units (LRUs):

• Primary Flight Display (PFD)

• Multi Function Display (MFD)

• Integrated Avionics Unit (2)

• Audio Panel

• Mode S Transponder

The MFD/PFD controls are used to tune the communication transceivers and navigation radios.

The Audio Panel provides the traditional audio selector functions of microphone and receiver audio selection.  

The Audio Panel includes an intercom system (ICS) between the pilot, copilot, and passengers, a marker beacon
receiver, and a COM clearance recorder. 

The Mode S transponder is controlled with softkeys and the FMS Knob located on the Primary Flight Display

(PFD). The Transponder Data Box is located to the left of the System Time Box. The data box displays the active
four-digit code, mode, and reply status (Figure 4-1).
