Wireless Headphones
The RSE system might include two sets of
wireless headphones. Each headphone has an
L marked on the left-side, for the left ear and an
R marked on the right-side, for the right ear. The
L and R marks are to show how the headphones
should be worn.
OFF/ON (Power):The wireless headphones have
an OFF/ON power switch located on the
earpiece. To use the headphones, turn the switch
to ON. An indicator light on the earpiece of the
headphones illuminates. If the light does not
illuminate, the batteries might need to be replaced.
See “Battery Replacement” later in this section.
Switch the headphones to OFF when not in use.
The headphones shut off automatically to save the
battery power if the RSE system is shut off or if
the headphones are out of range of the transmitter
window for more than three minutes. The
transmitter window is located on the bottom edge
of the monitor. If you move too far forward or
step out of the vehicle, the headphones could lose
the audio signal.Channel Selector:The wireless headphones
have a channel selector switch located on the right
earpiece. The channel selector switches between
Channel A and Channel B. Since each monitor
can function as two independent sources through
auxiliary input, it is necessary to transmit audio
signals on separate channels. The driver’s
side monitor is designated as Channel A, and the
passenger’s side as Channel B. The Headphone
channel selector switch must be set to the
correct channel according to the monitor being
viewed. When the head restraint monitor is initially
turned on, the message, “To listen to this
monitor tune your headphones to channel A
(or B)” displays for ve seconds then disappears.
VOL
0(Volume):To adjust the volume
on the wireless headphones, use the volume
control.
Notice:Do not store the headphones in heat
or direct sunlight. This could damage the
headphones and repairs will not be covered by
your warranty. Keep the headphones stored
in a cool, dry place.

If there is a decreased audio signal during CD,
MP3, or DVD play, there could be a soft hissing
noise through the speakers and/or headphones.
If the hissing sound in the wireless headphones
seem excessive, make sure the headphone
batteries are fully charged. A small amount of
hissing is normal.
Battery Replacement
To change the batteries, do the following:
1. Press down on the left earpiece and slide the
battery compartment panel down to expose
the battery compartment.
2. Replace the two AAA batteries in the
compartment. Make sure they are installed
correctly using the diagram on the inside
of the battery compartment.
3. Slide the battery compartment panel back and
then down until the panel closes into the
headphone ear piece.
If the headphones are to be stored for a long
period of time, remove the batteries, and keep
them in a cool, dry place.

Audio Output
Audio from the DVD player or auxiliary devices
can be heard through the vehicle speakers or the
wireless/wired headphones. The FM Modulator
control has to be set to one of eight frequencies in
order for these devices to be heard through the
vehicle’s speakers. See “FM Modulator Control”
later in this section.
273

Vehicle Speakers
Only one audio source can be heard through the
vehicle’s speakers at a time. The audio source
being used is specied by the A/V (audio/video)
source selected on the driver’s side head restraint
monitor.
The RSE system or an auxiliary device can be
heard through all of the vehicle’s speakers when a
DVD or auxiliary device is playing and the radio
is tuned to one of eight frequencies selected
on the FM Modulator portion of the system’s
remote control. See “FM Modulator Control” later
in this section.
To turn the RSE system audio output to the
vehicle’s speakers, on or off, press the power
button on the FM Modulator portion of the system’s
remote control. The audio from the RSE system
can be heard through the wireless/wired
headphones and the vehicle’s speakers at the
same time. The volume on the radio can
vary when switching between the radio, CD, DVD,
MP3, or an auxiliary device.
Video Screens
The video screens are located on the backside of

The infrared LED window sends audio signals
to the wireless headphones. The infrared
LED window is located on the lower front
monitor, surrounding the monitor’s faceplate
buttons. In order for the infrared LED window
to work properly, it must remain unobstructed
at all times.
X(Wired Headphone Jack):This type of
headphone jack is used with universal wired
headphones (not included). The wired headphone
volume is adjusted using the up and down
arrow buttons. See “Wired Headphones” earlier in
this section.AUX (Auxiliary):The auxiliary input jack is an
AV 3 input jack. The auxiliary input jack is located
on the left lower side of the monitor, next to the
wired headphone jack. This auxiliary input jack lets
you view auxiliary sources such as portable
DVD units, game stations, video cameras, etc., on
each individual monitor. The sources connected
to these inputs cannot be shared between
the monitors.
Press the SOURCE soft key button on either
monitor, or the SOURCE button on the system’s
remote control to select the desired auxiliary
source. See “SOURCE” under Video Screens
earlier in this section.

Cleaning the Video Screens
The video display screens are made of a specially
coated glass and can be scratched or damaged
by abrasive products, solvents, or ammonia-based
window cleaners. Occasionally take a soft,
lint-free, cotton cloth that has been slightly
dampened with warm water and wrung out
completely. Dry the screens by wiping with a clean
dry cotton cloth.
293

Cleaning the Components
Use care when directly touching or cleaning the
components such as the DVD player and the discs
that are used for your viewing entertainment, as
damage may result. SeeCare of the CD and
DVD Player on page 300andCare of Your CDs
and DVDs on page 299in this manual for
more information.
Rear Seat Audio (RSA)
This feature allows rear seat passengers to listen
to any of the sources: radio, cassette tapes, or
CDs. 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 or CDs 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 tape, or CD.

Radio Reception
You may experience frequency interference and
static during normal radio reception if items
such as cellphone chargers, vehicle convenience
accessories, and external electronic devices
are plugged into the accessory power outlet. If
there is interference or static, unplug the item from
the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can cause
station frequencies to interfere with each other.
For better radio reception, most AM radio stations
boosts the power levels during the day, and then
reduce these levels during the night. Static can also
occur when things like storms and power lines
interfere with radio reception. When this happens,
try reducing the treble on your radio.
FM Stereo
FM stereo gives the best sound, but FM signals
reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals,
causing the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels can cause
loss of the XM™ signal for a period of time.
The radio could display NO SIGNAL to indicate
interference.
Care of the Cassette Tape Player
A tape player that is not cleaned regularly
can cause reduced sound quality, ruined
cassettes, or a damaged mechanism. Cassette
tapes should be stored in their cases away
from contaminants, direct sunlight, and extreme
heat. If they are not, they may not operate properly
or may cause failure of the tape player.
