134 Audio System Wireless Headphones This unit includes a built-in dual channel infrared transmitter for use with your wireless headphones. You can change headphone volume using the individual controls on each headset. To use wireless headphones effectively, you must maintain line-of-sight between headphones and transmitter. Allowing obstructions to come between headphone and transmitter, or body motions that allow the user to conceal the headphone from the transmitter (like reaching or bending), adversely affect audio performance. Infrared transmission, like visible light, travels only in a straight line. Wired Headphones You can use any standard stereo headphones by plugging them into the 1/8-inch (3.5 millimeter) headphone jack on each of the headrest DVD systems. Remove and save the protective plastic cover to access the jacks. Remember to replace the cover when the jacks are not in use. A/V Input You can connect an external audio/video device that uses common RCA interface cables to the Ford DVD system, such as a video game device or VCR. Connect the device RCA cables to the AV RCA INPUT jacks according to color: yellow for video, red for right audio and white for left audio. The signal from the external audio/video source overrides other video sources for that monitor. Wireless FM Transmitter Your device has an internal FM transmitter. This allows you to listen to the DVD player audio signal by tuning your vehicle FM radio to a radio frequency that you select, then accessing the SOUND-AROUND feature by using the remote control. SOUND-AROUND allows the user to choose from a number of pre-programmed frequencies to play back the rear-seat entertainment system audio over the radio. When you engage SOUND-AROUND, as long as the DVD player is active, it adversely affects the FM radio reception of other stations, especially neighboring stations nearest to whichever station is in use for the DVD player. Performance of SOUND-AROUND varies based on geographic location. You may need to change the SOUND-AROUND frequency periodically when travelling long distances. This helps maintain the best performance when listening to DVD system content over the radio. Audio heard through wireless headphones remains unaffected by SOUND-AROUND. There may also be a reduction in AM radio performance as well. AM and FM radio performance can be expected to return to normal when the DVD system is turned off. 2013 Expedition (exd) Owners Guide gf, 3rd Printing, April 2013 USA (fus)
