The aerocom III has a ⅛” jack for
Stereo Music, a power jack for
aircraft power, which disconnects
the battery.
The aerocom III is expandable to
4-place intercom using the 2717A
expansion unit and the expansion
jack.
Appendix A,
PTT Modifications
When received from the manufac-
turer, an after-market PTT switch
opens the mic audio path to the "ring"
connection of the PTT mic plug. When
the PTT is between the intercom and
the headset, the intercom audio path
will not work until the PTT switch is
depressed. A simple modification can
be performed to allow proper intercom
operation.
NOTE: This modification does not
alter normal radio operation.
Due to the variety of different PTT
manufacturers, we can’t provide all of
the specific instructions. Contact the
PTT manufacturer if you require more
information, or purchase a modified
PTT from PS Engineering for $24.95.
