Headphones The RSE system includes two sets of wireless infrared 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" later in this section for more information. To turn the headphones OFF activate the ON/OFF control. Each set of headphones has a volume knob. To adjust the volume, adjust this knob. 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. 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. 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. 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 screw to close the compartment door. 3-118
