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.
