Troubleshooting—Continued

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

Playback jumps.

• The CD receiver is being subjected to vibration or the disc is scratched or dirty (see page 16).

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 16).

•If condensation is suspected, turn on the CD receiver and leave it for 1 hour before playing any discs.

•Some CD-R/RW discs may not be playable (see page 15).

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 discs

•Use only ISO 9660 Level 1 or Level 2 format discs (see page 15).

•The disc has not been finalized. Finalize the disc.

•MP3 files without a “.mp3” or “.MP3” filename extension are not recognized.

Tuner

Reception is noisy, stereo FM reception suffers from hiss, the Auto Preset function doesn’t preset all stations, or the ST indicator doesn’t light up when tuned to a stereo FM station.

•Check the antenna connections (see page 17).

•Change the position of the antenna (see page 41).

•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 41).

•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 (see page 18).

If a power outage occurs or the power cable is disconnected:

•If the preset stations are lost, preset them again (see pages 46, 47).

•The clock and timer settings will be lost. Set the clock and timers again (see pages 52, 53).

Can’t adjust the frequency of the radio.

• Use the Rewind and Fast Forward [5]/[4] buttons to change the frequency of the radio (see page 41).

RDS doesn’t work.

•The FM station you are tuned to doesn’t support RDS.

•Install an outdoor FM antenna (see page 18).

•Change the position or direction of your outdoor FM antenna (see pages 18, 41).

•Move the FM antenna as far away as possible from fluorescent lights (see page 41).

Remote Controller

The remote controller doesn’t work properly.

•Make sure the batteries have been installed with the correct polarity (+/–) (see page 6).

•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 6).

•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.
