3-16 Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen to and
control any of the music sources, including AM FM,
cassette tapes and CDs, through the Rear Seat Audio
(RSA) controller. However, the rear seat passengers
can only control the music sources that the front seat
passengers are not listening to. For example, rear seat
passengers may listen to a cassette tape through
headphones and have control over the cassette tape
playing while the driver listens to the radio through the
front speakers. If rear seat passengers choose to listen
to the radio while the driver is listening to the radio they
will not be able to control the radio.The rear seat passengers have control of the volume for
each set of headphones. Be aware that 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 play
the same remote source. The rear speakers will be muted
when the RSA power is turned on. You may operate the
RSA functions even when the main radio is off.
The following function is controlled by the knob on the
main radio:
PWR VOL: Push this knob twice to turn RSA off.
The following functions are controlled by the RSA
system buttons:
PWR: Press this button to turn RSA on or off.
VOL: Press this knob lightly so it extends. Turn
the knob clockwise to increase volume and
counterclockwise to decrease volume. Push the knob
back into its stored position when you're not using it.
The upper VOL knob controls the upper headphone and
the lower VOL knob controls the lower headphone.
