PMA8000B Pilot Guide Rev. 7
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.
