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 con-
trolled by three Smart Func-
tion Keys (SFK) controlled
from the front panel. See Page
12—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 advi-
sory 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.
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.
Smart Jack Function
When the PMA8000B MP3 has an active audio signal on music #1
input coming in from the rear connector, or the MP3 player is active,
the front panel jack automatically becomes a Priority Advisory input,
