Monitor Function (11)

The MON 1 and Mon 2 buttons allow

the pilot to listen to the standby fre-

quencies selected by the Entegra

ACD215 Control/Display Unit. Note: These audio sources are muted

during transmit to prevent bleed through.

Telephone (TEL) (9)

The TEL mode serves as a full duplex interface

and distribution for telephone systems such as

AirCell or portable cellular phones with ear-

piece jacks. Pressing the TEL button activates

the telephone mode.

This connects the telephone to the users as follows:

In ALL 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 tele-

phone. Passengers will not hear the telephone. The pilot and copilot

will also have transmit capability on the other selected transceiver.

In ISO mode, when the PMA8000B MP3 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 au-

dio is provided to the pilot.

Cockpit Speaker (6)

The SPR in the lower right section stands for

speaker. This button will place all selected audio

on the cockpit speaker when this switch is se-

Note: As shipped from PS Engineering, the PMA8000B-MP3 does not provide cellular telephone

sidetone (the user’s voice fed back to the headset). Some cell phones do not provide sidetone. In

PMA8000B MP3 Avidyne audio panels above serial number C10251, Telephone sidetone can be

enabled by pressing the Shift (MON 1) and TEL buttons for more than one second.

Because the cell-phone uses an intercom circuit, all stations on that circuit will lose intercom

capability when the cell phone is in use, unless sidetone is present.
