The playback will stop whenever there is more incoming selected
com audio, and the message can be replayed from the beginning.
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 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 MP3 audio panel
will connect the intercom to
the cell phone when the
“TEL” button is pressed (9).
When the TEL mode is off,
the telephone 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 way-
point or autopilot
tones. These still must
be hard wired into the
back by your installer.
