Headphones The RSE system includes two sets of wireless headphones. Each set of headphones has an ON/OFF control. An indicator light will illuminate on the headphones when they are on. If the light does not illuminate, the batteries may need to be replaced. See "Battery Replacement" following for more information. Each set of headphones has a volume knob. To adjust the volume, adjust this knob. The transmitters are located below the video display screen. The headphones will shut off automatically if they lose the signal from the system after about four minutes to save battery power. The signal may be lost if the system is turned off or if the headphones are out of range of the transmitters. When using the wired headphones, if the front seat passengers play a CD in the Radio with Six-Disc CD (if equipped) or use XM™ Satellite Radio Service (if equipped), you will hear the audio for these sources, instead of the DVD or CD that is currently playing through the RSE. Notice: Do not store the headphones in heat or direct sunlight. This could damage the headphones and repairs would not be covered by your warranty. Keep the headphones stored in a cool, dry place. 3-114 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, using the diagram on the inside of the battery compartment. 3. Tighten the screw to close the compartment door. 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.
