The RSE system always transmits the audio
signal by infrared to the wireless headphones,
if there is audio available. See "Headphones"
previously for more information.
The RSE system is capable of outputting audio
to the vehicle speakers by using the radio.
The RSE system can be selected as an audio
source on the radio if the RSE system power is on.
Once the RSE system is selected as an audio
source on the radio, adjust the speaker volume on
the radio, if necessary. If the RSE system power
is not on, the RSE system is not an available
source on the radio. Refer to the radio information
for the radio that your vehicle has for more
information.
The RSE system is capable of outputting audio
to the wired headphone jacks on the rear
seat audio system (if equipped). The RSE system
can be selected as an audio source on the rear
seat audio system if the RSE system power is on.
Refer to Rear Seat Audio (RSA) on page 298
for more information.
Video Screen
The video screen is located in the overhead
console.
To use the video screen, do the following:
1. Push forward on the release button located
on the DVD display console.
2. Pull the screen down, away from you, and
adjust its position as desired.
When the video screen is not in use, push it up
into its locked position.
If a DVD is playing and the screen is raised to
its locked position, the screen shuts off, but
the DVD continues to play through the previous
audio or video source.
The video screen contains the IR transmitters for
the wireless headphones and the IR receivers
for the remote control. If the screen is in the closed
position, the signals are not available for the
operation of the headphones or the remote control.
Notice: Avoid directly touching the video
screen, as damage may occur. See "Cleaning
the Video Screen" later in this section for
more information.
