PASSENGER HEADSET CONSIDERATIONS
The A711L has the ability to drive passenger ICS in both PTT or VOX modes, but you must consider
this: Loose passenger headsets lying in the cabin MUST be properly accounted for. If the
headsets are wired in directly, the loose headsets will be a continual source of intercom noise,
rattling around the cabin. They have to be un-plugged when not in use, or connected via a drop cord
that provides either PTT or continuous mic connection. This is VERY important, and must be
considered during installation and operation both. The industry default is to use a drop cord
of some type, but other methods are possible, just be certain this issue has been resolved to the
satisfaction of the flight crew BEFORE flight, as it cannot be corrected once airborne, without
impacting flight operations.
