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 headphones. 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. 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 and the mini-headphone jacks are located behind the video screen on the overhead console. The RCA jacks allow you to hook up an auxiliary device such as a camcorder or a video game unit. The yellow RCA jack is used for video and the red and white RCA jacks are used for audio. You may require adapter connectors or cables to connect your auxiliary device to the RCA jacks. Refer to the manufacturer's instructions for proper usage. The mini-headphone jacks allow you to hook up two customer provided wired headphones. To use the auxiliary audio and video inputs on the RSE, connect an external auxiliary device such as a camcorder to the RCA jacks and turn on both the auxiliary device power and the power on the front of the RSE player. If a disc is not present in the player, the auxiliary signal will immediately be displayed on the RSE. If a disc is present when the RSE power is turned on, the player will automatically begin playing the disc and the user will need to press the AUX button on the remote control to display and/or hear the auxiliary input signals. Each press of the AUX button on the remote control will switch the system between disc and auxiliary input. The wired headphone volume control will only operate when the DVD player power is turned on and it controls both wired headphone jacks at the same time. See Remote Control later in this section for more information. Audio Speakers Audio from the DVD player can only be heard either through the IR headphones or wired headphones (not included). The sound will not come through the vehicle's speakers. 3-93
