Certain PMA450C’s have an additional Bluetooth Module that can be used as an audio input (useful for EFB
such as ForeFlight or music & entertainment).
As shipped, the BT2 module is configured as a music input. It can be reconfigured in the User Setup as an

Communications Antenna Installation Notes
For best results while in Split Mode, it is recommended that the one VHF communications antenna is located
on top of the aircraft while the other communications antenna is installed on the bottom. Any antenna relo-
cation must be accomplished in accordance with AC 43.13-2B, aircraft manufacturers’ recommendations and
FAA-approved technical data.
WARNING
It is probable that radio interference will occur in the split mode when the frequencies of the two air-
craft radios are adjacent, and/or the antennas are physically close together.
PS Engineering makes no
expressed or implied warranties regarding the suitability of the PMA450C in Split Mode.
