The AC power cord is not plugged in.

The CD is upside down.

The CD is dirty or scratched.

Small tabs on the back of the cassette are removed.

The built-in microprocessor has malfunctioned due to external electrical interference.

You are trying to play back a CD which cannot be played or there is a problem with the CD.

The CD tray does not open correctly because of the obstruction.

You are trying to play back a CD-R/RW which has not been “finalized” yet.

This unit automatically turns off and on during demonstration. If volume level is set high, you will hear this noise.

Action

•Remove the obstruction.

•Replace the batteries. (See page 6.)

•Signals cannot reach the remote sensor. Move closer to the unit.

•Reconnect the antenna securely.

•Change the position and direction of the AM loop antenna.

•Extend FM antenna to the best reception position.
