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

Audio Advisory Input
The front jack can be
used as a priority ad-
visory input for auxil-
iary systems such as a
GPS terrain advisory
or portable traffic
watch system. To pre-
vent radio or intercom from muting this input, press the “Mute” but-
ton.
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 has a signal on music #1 input coming in from
the rear connector, the front panel jack automatically becomes a Pri-
ority Advisory input, and is heard in the crew headphones. This input
will NOT be muted by radio or intercom provided that music 1 on the
rear connector has an active audio signal. If this signal is not present,
this input may be muted, unless the Mute is deselected.
Music Input
When used as a music input, the front panel jack is treated as Music
#1. However, thanks to the function controls, it can be distributed to
all users, depending on the intercom mode.
Smart Function Keys (SFK)
With Virtual Tech Support, the configuration process is self-directed.
Once you’ve set up your system, you don’t need to change it again,
unless you want to. The unit will always remember your settings.
Note: VTS annunciations will be stopped by any audio received on
the com radio selected for transmit.
These functions are non-essential and non-required and as such are
only an accessory capability. They don’t affect the audio panel’s pri-
