FORD 2011 Flex v.1 - Manual (Page 57)

Ensure that the headphones are turned off when not in use. After
approximately one minute of not being in use (no infrared signal is
received), the wireless headphones will automatically turn off. They will
also turn off after two hours of continuous use as a power save feature.
If this happens, simply turn the headphones on again and continue use.
Wired headphones
WARNING: Do not leave children unattended in the vehicle and
do not let children operate the system while unsupervised. If
wired headphones or auxiliary systems are used, children may become
entangled in the cords and seriously injure themselves.
WARNING: The driver should never use the headphones while
driving the vehicle. Using headphones may prevent the driver
from hearing audible warnings such as horns or emergency sirens,
which could result in a crash causing serious injury. Give your full
attention to driving and to the road.
Wired headphone jacks on the FES (Family Entertainment System) are
universal so you may purchase and use additional wired headphones for
your system. Plug them into the 3.5 mm headphone jack(s) located
behind the trim covers on the face of each monitor. These headphones
will be active when in Dual Play mode.
To listen to the audio on wired headphones (not included), connect the
wired headphones into the monitor headphone jacks. Available wired
headphone sources are limited to the sources available to whichever
monitor is being listened to. Adjust the volume using the volume control
on the DVD system remote control.
Operation
Single play/dual play
Your DVD and audio system work together with the infrared headphones
and wired headphones (not included) to allow the rear seat passengers
to listen to the radio (and other media sources) over the headphones.
This enables the front and rear seat passengers to listen to a variety of
sources a variety of ways.
Single Play: Single play consists of all occupants in the vehicle listening
to the same playing media over the front and rear speakers. When the
DVD system is on and in single play, the same source will play through
all vehicle speakers.
