Installed DC power connector
An optional installed connector is available for pilots who want to use
their plane’s DC power, instead of the battery pack, with the portable
adapter cable. The connector’s small size allows it to be installed in a
convenient location in the control panel, for example, near the head-
phone and mic jacks.
Installing the DC power connector

This installation must be done by mechanics qualified to
perform this type of avionics installation for the aircraft in which the
installed connector will be used.
