Both sets of rear seat headphones may include foam ear pads that can be replaced. Foam ear pads on these headphones may become worn or damaged. The headphone foam ear pads can become damaged if they are not handled or stored properly. If the foam ear pads do become damaged or worn out, the pads can be replaced separately from the headphone set. It is not necessary to replace the complete headphone set. The headphone replacement foam ear pads can be ordered in pairs. See your dealer for more information. 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 will switch 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, 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. 3-126
