Battery Replacement
To change the batteries on the headphones:
1. Loosen the screw to the battery door on the left
side of the headphones and slide open.
2. Replace the two batteries in the compartment.
Install 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.
Stereo RCA Jacks
The RCA jacks are located behind the video screen.
The RCA jacks allow audio and video signals to be
connected from an auxiliary device such as a camcorder
or a video game unit to the RSE system. Standard RCA
cables, not included, are needed to connect the auxiliary
device to the RCA jacks. The yellow connector inputs
video and the red and white connectors input right and
left audio. Refer to the manufacturer’s instructions for
proper connection of the auxiliary device.
To use the auxiliary inputs on the RSE system, connect
an external auxiliary device to the color-coded RCA jacks
and turn both the auxiliary device and the RSE system
power on. If the RSE system had been previously in the
DVD player mode, pressing the SRCE button on the
faceplate or the remote control switches the RSE system
between the auxiliary device and the DVD player.
