Troubleshooting
Audio performance.
• Audio performance will be at its best about 10 to 30 minutes after the CD receiver has been turned on and had time
to warm up.
• Using cable ties to bundle audio cables with speaker or power cables may degrade the sound quality, so don't do it.
CD Playback
The disc will not play.
• Make sure the disc has been loaded correctly, with the label-side facing up.
• Check to see if the surface of the disc is dirty (see page 12).
• If condensation is suspected, turn on the CD receiver and leave it for 2 to 3 hours before playing any discs.
• Some CD-R/RW discs may not be playable (see page 12).
It takes a long time for playback to start.
• It may take the CD receiver a while to read CDs that contain many tracks or files.
Playback jumps.
• The CD receiver is being subjected to vibration or the disc is scratched or dirty (see page 13).
• The volume may be too loud. Turn down the volume (see page 17).
Can't play MP3 Discs.
• Use only ISO 9660 Level 1 or Level 2 format discs (see page 12).
• The disc has not been finalized. Finalize the disc.
• Check whether the file format is supported (see page 12).
• MP3 files without a ".MP3" or ".mp3" filename extension are not recognized.
iPod/iPhone/iPad
There's no sound.
• Check if "iPod" appears on the display of the CD receiver. If "USB" appears, switch the connection mode to iPod

Can't control your iPod/iPhone/iPad with the CD receiver's remote controller.
• Your iPod/iPhone/iPad may not work soon after it is connected to the CD receiver with a USB cable. In this case, wait
a few moments until your iPod/iPhone/iPad wakes up.
• Depending on your iPod/iPhone/iPad model, its software version, or the content you're playing, some functions may
not work as expected (see page 22).
• The iPod/iPhone/iPad might not be connected if its power is turned off, or if it is insufficiently charged. Check the
state of your iPod/iPhone/iPad.

(see page 22).
