HOW TO USE THE STEREO SOUND SYSTEM
To play music or audio books through the console's
stereo speakers, you must connect your iPod, MP3
player, CD player, or other personal audio player to the
console through the audio jack.
Plug one end of your audio cable into the audio jack
on the console. Plug the other end into a jack on your
MP3 player, CD player, or other personal audio player.
Make sure that your audio cable is fully plugged in.
Next, press the play button
on your iPod, MP3 player,
CD player, or other personal
audio player. Adjust the vol-
ume on your personal audio
player or press the volume
increase and decrease buttons on the console.
If you are using a personal CD player and the CD
skips, set the CD player on the floor or another flat
surface and not on the console.
