Select either of the com XMT buttons to exit the split mode. It is not possi-
ble to have the pilot on Com 2 and copilot on COM 1 in split mode.
N O T E : Due to the nature of VHF communications signals, and the
size constraints in general aviation aircraft, it is probable that there
will be some bleed-over in the Split mode, particularly on adjacent
frequencies. PS Engineering makes no warranty about the suitability
of Split Mode in all aircraft conditions.
Telephone (TEL) (10)
The TEL mode serves as a full duplex interface and distribu-
tion for telephone systems such as portable cellular phones
with earpiece jacks or Bluetooth connectivity. Pressing the
button connects the telephone to the users as follows:
In ALL intercom mode, all crew and passengers will be heard on the phone
when they speak. Com and other selected radio audio is also heard in the
headsets. If the pilot or copilot pushes the radio PTT, their mic will be trans-
ferred to the selected Com radio. The telephone party will not hear ATC
communications, and vice versa.
In CREW mode, only the pilot and copilot are connected to the telephone.
Passengers will not hear the telephone.
In ISO intercom mode, only the pilot will hear the telephone, and only he
will be heard. He will also have access to Com 1 or 2, and will transmit on
that radio using the PTT. Selected radio audio is provided to the pilot.
In cases where the cellular telephone doesn’t provide sidetone, the audio
panel can be configured, by holding the TEL and ADF buttons for more than
one second, to create sidetone for you.
Warning:
United States FCC Regulations contained in 47 CFR § 22.925 contain prohi-
bition on airborne operation of cellular telephones. “Cellular telephones in-
stalled in or carried aboard airplanes, balloons or any other type of aircraft
must not be operated while such aircraft are airborne (not touching the
ground). When any aircraft leaves the ground, all cellular telephones on
board that aircraft must be turned off.”
Utility Jack
The 2.5 millimeter (3/32”) jack on the front of the PMA8000BT has three
distinct functions:

Cell phone input (wired)

Advisory audio input

Music input (wired)
