Troubleshooting—Continued
CD Playback
Playback jumps.
• The CD receiver is being subjected to vibration or the disc is scratched or dirty (see page 12).
Can't add tracks to the playlist for memory playback.
• Make sure there's a disc in the CD receiver. Also, you can only add valid track numbers. For example, if the CD
contains 11 tracks, you cannot add track #12.
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).
• 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.
Can't Play MP3/WMA/AAC discs.
• Use only ISO 9660 Level 1 or Level 2 format discs (see page 12).
• The disc has not been finalized. Finalize the disc.
• MP3/WMA/AAC files without a ".MP3/.WMA/.AAC" or ".mp3/.wma/.aac" filename extension are not recognized.
Tuner
Reception is noisy, stereo FM reception suffers from hiss, the Auto Preset function doesn't preset all
stations, when tuned to a stereo FM station.
• Check the antenna connections (see page 14).
• Change the position of the antenna.
• Move the CD receiver away from a nearby TV or computer.
• Cars or airplanes can cause noisy interference.
• The radio signal will be weakened if it has to pass through a concrete wall before reaching the antenna.
• Try setting FM mode to mono (see page 31).
• Move power cords and speaker cables as far away as possible from the tuner's antenna.
• When listening to an AM station, noise may be heard when you operate the remote controller.
• If none of the above improves the reception, install an outdoor antenna.
If a power outage occurs or the power cable is disconnected.
• If the preset stations are lost, preset them again (see pages 31, 32).
Can't adjust the frequency of the radio.
• Use the Fast Reverse and Fast Forward [
RDS doesn't work.
• The FM station you are tuned to doesn't support RDS.
• Install an outdoor FM antenna.
• Change the position or direction of your outdoor FM antenna.
• Move the FM antenna as far away as possible from fluorescent lights.
Remote Controller
The remote controller doesn't work properly.
• Make sure the batteries have been installed with the correct polarity (+/–) (see page 7).
• Replace both batteries with new ones. (Do not mix different types of batteries or new and old batteries.)
• The remote controller is too far away from the CD receiver, or there's an obstacle between them (see page 7).
• The CD receiver's remote control sensor is being subjected to bright light (inverter-type fluorescent light or sunlight).
• The CD receiver is located behind the glass doors of a audio rack or cabinet.
