NOTE
Because the cell phone uses an intercom circuit, all stations on that circuit will lose intercom capability
when the cell phone is in use. Intercom conversations will still be present if the cell phone provides
sidetone, or if the audio panel is modified for telephone sidetone.
PS Engineering does not guarantee compatibility with personal cellular telephones.

3.9.1 Cellular telephone sidetone
As shipped from PS Engineering, the PMA8000BT does NOT provide cellular telephone sidetone (the us-
er’s voice fed back to the headset). Some cell phones do not provide sidetone. In PMA8000BT Telephone
sidetone can be enabled by pressing the TEL and ADF buttons for more than one second.
3.10 Utility Jack
The 2.5-millimeter (3/32”) jack on the front of the PMA8000BT 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
PMA8000BT 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
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 PMA8000BT has a signal on music #1
input coming in from the rear connector, the front
panel jack automatically becomes a Priority Adviso-
ry 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. The front jack input will be muted by
radio or intercom unless music is actively playing in the rear connector. Consequently, it is possible that an
alert may be missed unless the mute mode is deselected.
3.10.3
Music Input
When used as a music input, the front panel jack is treated as Music #1. However, thanks to the function
controls, it can be distributed to all users, depending on the intercom mode. A patch cord is available with
2.5 mm to 3.5 mm (3/32 to 1/8”) adapter cord (PS Part Number 425-006-2535).
