phones, scanners, CB radios, Global Position Systems
(GPS)*, two-way radios, mobile fax, or walkie talkies.
It might be necessary to turn off the DVD player when
operating one of these devices in or near the vehicle.

When cleaning the video screen, use only a clean cloth

touching or cleaning the screen, as damage could result.
Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to and
control any of the music sources: radio, CDs, DVDs, or
other auxiliary sources. However, the rear seat
passengers can only control the music sources the front
seat passengers are not listening to (except on some
radios where dual control is allowed). For example, rear
seat passengers can control and listen to a CD through
the headphones, while the driver listens to the radio
through the front speakers. The rear seat passengers
have control of the volume for each set of headphones.
You can operate the RSA functions even when the main
radio is off. The front audio system will display the
headphone icon when the RSA is on, and will disappear
from the display when it is off.
Audio can be heard through wired headphones (not
included) plugged into the jacks on the RSA. If
your vehicle has this feature, audio can also be heard
on Channel 2 of the wireless headphones.
