Select either of the com XMT buttons to exit the split mode. It is not possible
to have the pilot on Com 2 and copilot on COM 1 in split mode.
NOTE: 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 transferred 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.
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)
Cellular phone
When a cellular telephone is connected to this jack using an adapter cord (PS
Part Number 425-006-7026), the PMA8000BT audio panel will connect the
intercom to the cell phone when the “TEL” button is pressed (9). When the
TEL mode is off, the telephone ringer audio will be heard if it is present on
the telephone’s output (ringer may be muted by radio and intercom).
