intercom from muting this input, disable the “Mute” function.
3.9.3.1 Smart Jack Function
When the PMA9000EX has a signal on music #1 input coming in from the rear connector, the front panel
jack automatically becomes a Priority Advisory input, and is heard in the crew headphones.
NOTE
The front jack is no substitute for the certified installation of alerts such as the GPS waypoint or autopilot
tones. These still must be hard wired into the back by your installer.
3.10 Telephone Mode
3.10.1 Bluetooth Telephone Connection
Before the PMA9000EX can be used in TELEPHONE mode with a wireless Bluetooth connection, the
unit must be associated with a specific phone. This must be done after each power cycle of the
PMA89000EX.
Activate the “seek device” function on the cell phone, and then enter the access code “0000” when the
phone detects the “PMA9000EX” on the list of available devices.
This process will be necessary for any phone to be used, and only one cell phone can be associated with
the audio panel at a time. If the additional phones are associated with the PMA9000EX at the same time,
only the first phone will transfer audio to the panel.
3.10.2 Telephone (TEL) Operation
The TEL mode serves as a full duplex interface and distribution for tel ephone systems such as AirCell or
portable cellular phones with earpiece jacks. Select TEL -> ON to activate the telephone mode.
From the main display, select TEL to ON to make an outgoing call.
When the Bluetooth-enabled phone receives an incoming call, the PMA9000EX display will show
“Telephone Ringing” and play a ring tone. Pressing the encoder knob will connect the call, if desired. The
PMA9000EX exits the telephone mode automatically wh en the cellular phone hangs up.
In TELEPHONE mode, the pilot microphone and headphones are connected to the cell phone. The pilot
PTT will switch the pilot mic to the selected com transceiver, and allow continued aircraft
communications to continue.
The copilot will also be able to transmit on the other selected radio with his PTT as well.
Entering the TEL mode 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 communic a-
tions, and vice versa.
In CREW mode, only the pilot and copilot are connected to the telephone. Passengers will not hear the
telephone. The pilot and copilot will also have transmit capability on the other selected transceiver.
In ISO intercom mode, when the PMA9000EX is in the TEL mode, the pilot position is in the "Phone
Booth." 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. All selected audio is provided to the pilot.
NOTE
Because the cell-phone uses an intercom circuit, all stations on that circuit will lose intercom capabi lity
when the cell phone is in use.
WARNING
Federal Communications Commission regulation 47 CFR 22.925 prohibits the use of 800MHz Cellular
handsets in any aircraft that is airborne. Violation of this rule could result in suspension of service and/or
