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. How to Change the Video Format when in the Auxiliary Mode The auxiliary input video format is preset to NTSC. In some countries, the video format may be in PAL system. To change the video format, perform the following: 1. Press the display menu button. 2. Press the down arrow button to highlight the Video Format option. 3. Press the enter button to select Video Format. 4. Press the right or left arrow button to select the desired video format. 5. Press the enter button to accept the change. 3-108
