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, unless the cellular phone provides it’s own sidetone.
PS Engineering does not guarantee compatibility with personal cellular telephones.

3.10 Utility Jack
The 2.5-millimeter (3/32”) jack on the front of the PMA8000B-MP3 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-MP3 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 oth er
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 PMA8000B-MP3 has a signal on music
#1 input coming in from the rear connector (or
MP3 internal playing), the front panel jack
automatically becomes a Priority Advisory input,
and is heard in the crew headphones.
We’ve built some intelligence into the PMA8000B-MP3, too. If you have Music 1 connected to the rear
pins, and there is music playing, the PMA8000B-MP3 “knows” that what you put into the front jack must
be a priority. So the unit will automatically switch the j ack to the priority mode.
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 con-
nector. 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).
3.10.4 Smart Function Keys (SFK)
With Virtual Tech Support, the configuration process is self-directed. Once you’ve set up your system, you
don’t need to change it again, unless you want to. The unit will always remember your settings.
