Operation with an aftermarket audio system
(Headphone only mode)
When the Family Entertainment System (FES) detects that the original
radio supplied by Ford Motor Company has been removed from the

as “Headphone Only Mode”.
While operating in Headphone Only Mode, the system will have limited
functionality.
• The system will only output audio to the headphones. It will not be
capable of providing audio to the speakers.
• The available sources in FES Headphone Only Mode are DVD-DISC

• When a disc is inserted into the FES while in Headphone Only Mode,
both headphone channels (A&B) will be connected to FES-DISC.
