If you move too far forward, step out of the vehicle or break the "line of sight" between the headphones and the display above the video screen, the sound in the headphones will be degraded or will cut out entirely. If the system is shut off, or the headphones are out of the "line of sight" for more than three minutes, the headphones will shut off automatically to preserve battery life. If the channel switch located on the right side is on A, the headphones will play the DVD or auxiliary device. See "Stereo RCA Jacks" later in this section for more information. If the channel switch is on B, the headphones will play the rear seat audio system. See Rear Seat Audio (RSA) (Without Entertainment System) on page 3-94 or Rear Seat Audio (RSA) (With Enterfainment System) on page 3-96 for more information. To adjust the volume on the headphones, use the volume control located on the right side. Battery Replacement To change the batteries, do the following: 1. Slide open the battery 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. Slide the battery door shut. If the headphones are to be stored for a long period of time, remove the batteries and keep them in a cool, dry place. 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. 3-88
