Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to any
of the sources: radio, cassette tapes, CDs, or DVDs.
However, the rear seat passengers can only control the
sources that the front seat passengers are not
listening to. For example, rear seat passengers may
listen to and control cassette tapes, CDs, or DVDs
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.
The front seat audio controls always have priority over
the RSA controls. If the front seat passengers switch the
source for the main radio to a remote source, the RSA will
not be able to control the source. You can operate the
rear seat audio when the main radio is off.
P(Power):Press this button to turn the system on or
off. The rear speakers will be muted when the power
is turned on unless your vehicle is equipped with
the Bose
®audio system.
u(Volume):Turn this knob to increase or to
decrease the volume. The left knob controls the left
headphones and the right knob controls the right
headphones.
SRC (Source):Press this button to select a source:
radio, cassette tapes, CDs, or DVDs.
