Battery Replacement
To change the batteries on the
headphones:
1. Turn the screw to loosen the
battery door located on the
left side of the headphones.
Slide the battery door open.
2. Replace the two batteries in the
compartment. Make sure that
they are installed correctly, using
the diagram on the inside of the
battery compartment.
3. Replace the battery door and
tighten the door screw.
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/Video (A/V) Jacks
The A/V jacks, located on the rear
of the floor console, allow audio or
video signals to be connected from
an auxiliary device such as a
camcorder or a video game unit to
the RSE system. Adapter
connectors or cables (not included)
may be required to connect the
auxiliary device to the A/V jacks.
Refer to the manufacturer s
instructions for proper usage.
The A/V jacks are color coded to
match typical home entertainment
system equipment. The yellow
jack (A) is for the video input.
The white jack (B) is for the left
audio input. The red jack (C) is for
the right audio input.
Power for auxiliary devices is not
supplied by the radio system.
To use the auxiliary inputs of the
RSE system, connect an external
auxiliary device to the color-coded
A/V jacks and turn both the auxiliary
device and the video screen power
on. If the video screen is in the DVD
player mode, pressing the AUX
(auxiliary) button on the remote
control switches the video screen
from the DVD player mode to the
auxiliary device. The audio of the
connected source can be listened to
over the speakers by sourcing the
radio to the auxiliary device or by
sourcing the RSA to the Rear Aux
and listening with the wireless
headphones on Channel 2 or
with the wired headphones.
