Split Mode; Bluetooth Telephone; Stuck Microphone Protection - PS Engineering PMA8000C Operation Manual

Split Mode

The split mode can be activated at any time by pressing the COM 1 and
COM 2 COM 3 XMT buttons at the same time. This places the pilot on
OR
COM 1 and the Copilot on COM 2 or COM 3. If COM 2 and COM 3 XMT
buttons are pushed, the pilot will be on COM 2, and the Copilot will be on
COM 3.
Pilot on COM 2 or COM 3, and Copilot on COM 1 is not possible.
NO 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.
Bluetooth ® Telephone
The Bluetooth telephone mode serves as a full duplex interface and distribu-
tion for portable cellular phones Bluetooth connectivity. Calls can be made
and answered from the telephone only. The telephone connects 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, 2 or 3, 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 COM 3 and ADF buttons for more
than one second, to create sidetone for you.

Stuck Microphone Protection

The PMA8000C will sense if the pilot or copilot radio PTT remains keyed
for more than 32 seconds. When a stuck mic is detected, the key input is
ignored, and the other crewmember can transmit normally. If the stuck be-
comes ungrounded, normal operation is restored.
