The headphones will automatically turn off if they lose
the infrared signal from the system after approximately
four minutes in order to preserve their battery power.
The signal may be lost if the system is turned off or if the
headphones are out of range of the infrared signal
transmitters that are located below the video display
screen.
Battery Replacement
To change the batteries, do the following:
1. Loosen the screw on the battery compartment door
located on the left side of the headphone earpiece.
2. Replace the two AAA batteries in the compartment.
Make sure that they are installed correctly.
3. Tighten the screws to close the compartment door.
Notice: Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and would not be covered by your warranty.
Keep the headphones stored in a cool place.
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 on
the front of the DVD console. The RCA jacks allow
you to connect audio and video from an auxiliary device
such as a camcorder or a video game unit to your
RSE system just as you would to a standard television.
Standard RCA cables 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 stereo audio. Refer to the manufacturer's
instructions for proper connection of your 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, you will need
to press the SRCE button on the faceplate or the remote
control to change to the auxiliary mode. Pressing the
SRCE button will toggle the RSE system between
the auxiliary device and the DVD player.
