that there will be some bleed-over in
the Split mode, particularly on adjacent
frequencies. PS Engineering makes no
warranty about the suitability of Split
Mode in all aircraft conditions.
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 tele-
phone’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.
Note: Split Mode does not turn off NAV, ADF, or AUX selected audio to pilot. How-
ever, the copilot will only hear the selected com receiver and unswitched inputs.
The crew intercom is inhibited in Split Mode, but can be turned back on by pressing
the Mute button.
