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 Page 11—Smart Function Keys. 
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). When 
the TEL mode is off, the tele-
phone ringer audio will be 
heard if it is present on the telephone’s output (ringer may be muted 
by radio and intercom). 
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 sys-
tem. To prevent radio or intercom from muting this input, press the 
“Mute” button. 
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. 
We’ve built some intelligence into the PMA8000B, too.
