3.9.1 Cellular telephone sidetone
As shipped from PS Engineering, the PMA8000B 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 W04748, Telephone sidetone can be enabled by pressing the
TEL and ADF buttons for more than one second. For units with serial number W04747 and below, an
internal modification can be made that will allow the PMA8000B to provide sidetone. Contact PS Eng i-
neering for more information.
3.10 Utility Jack
The 2.5-millimeter (3/32”) jack on the front of the PMA8000B has three distinct functions:

Cell phone input
 Advisory audio input
 Music input
The use of this jack is controlled by three Smart Function Keys (SFK) controlled from the front panel. See
Section 3.11 — Smart Function Keys.
3.10.1 Cellular phone
When a cellular telephone is connected to this jack using a 2.5 mm
to 2.5 mm adapter cord (PS Part Number 425-006-7026), the
PMA8000B audio panel will connect the intercom to the cell phone
when the “TEL button is pressed (9), and behave as described in
section 3.7. The telephone ringer, if present, will be heard unless the input is muted by other radio or
intercom.
3.10.2 Audio Advisory Input
Serial J01861 and above: The front jack can be used as a priority advisory input for auxiliary systems
such as a GPS terrain advisory or portable traffic watch system. To prevent radio or intercom from muting
this input, press the “Mute” button.
3.10.2.1 Smart Jack Function
When the PMA8000B 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.
[Before Serial Number J01861 The front jack can be configured to be a priority advisory input for auxi l-
iary systems such as a GPS terrain advisory or portable traffic watch system. When configured as priority,
the audio is presented to the pilot and copilot only, and is NOT muted by radio or intercom activity. Co n-
nect the jack (J) to the output of the device with the advisory audio. The jack priority mode is activated by
pressing the Function Control F (TEL) and Function A (AUX) buttons at the same time. To disable the
jack as priority, select any other function. NOTE: This function not present in serial number J01861 and
above]
