level  for  the  pilot  and  copilot,  while  the  outer  knob  controls  the  passenger  intercom  volume.  Intercom
squelch is automatic.

An “Alternate Intercom Mode” is incorporated in

the PMA7000BT. This allows the passengers and crew to

converse, but removes radio traffic from the passengers’ headphones, and blocks passeng

er mics from the

crew during radio receptions.

A Bluetooth® module is included that adds music (as Music 1) connectivity as well as telephone interface
with Bluetooth-enabled smart phones.

A  3-light  Marker  Beacon  receiver  is  integrated  in  the PMA7000BT.  This  provides  the  necessary  Marker
Beacon lights and audio indications necessary for an Instrument Landing System (ILS) approach.

1.4
