 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
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.
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).
3.11 Smart Function Keys (SFK)
With Virtual Tech Support, the configuration process is self-directed. SFK annunciations are heard by the
pilot and copilot positions only. SFK annunciations will be heard by the copilot, even when the audio
panel is in pilot isolate mode. These annunciations will be stopped by any audio received on the com radio
selected for transmit.
