Troubleshooting

Problems may be caused by any component connected to this unit. Please check the table below, cross-referenc- ing the instruction manuals for the other components.

Power

The power to the system is not turned on.

Make sure that the power cable is plugged into the AC outlet.

Unplug the power cable from the AC outlet, wait for 10 seconds or more, then plug the cable in again.

The power is turned off during the operation.

If the SLEEP indicator is lit on the display, the Sleep timer is functioning. Cancel the Sleep timer. (See page 48.)

The CD receiver enters Standby mode after the timer playback or recording is complete. (See page 51.)

If the STANDBY indicator is blinking on and off, the built-in protection circuit is activated. Be careful not to short the positive and negative wires.

Audio

The sound is not heard.

Make sure the power cable is plugged into an AC outlet.

Make sure that the speakers are connected correctly and the speaker cables’ core wires touch only the speaker con- nectors. (See page 16.)

Check to make sure that the volume level is not set to minimum. (See page 22.)

Make sure that the input source is properly selected.

Check to make sure the muting function is not engaged.

If the MUTING indicator is flashing, the sound is muted. Cancel the muting function. (See page 23.)

When the headphones are connected, the speakers do not output any sound. Disconnect the headphones. (See page 22.)

Sound is not good.

Make sure that the speaker cords are connected correctly. Check their polarity (+/–). (See page 16.)

Connect the analog audio cables firmly. (See page 17.)

Sound quality could be affected by a strong magnetic field, such as a TV set. Locate such a device far from the CD receiver.

If you have any devices that emit high intensity radio waves near the CD receiver, such as a cellular phone in operation (calling), noise may be generated.

The CD receiver uses a rotating unit whose precision instrument generates faint hissing sound while reading a disc during playing back or searching a track; you may hear it in a very quiet environment.

Sound breaks off due to vibration.

The CD receiver is designed for use as a stationary type; place it in a location with limited influence of vibration.

Headphones makes noise or no sound.

There may be a bad contact. Clean the headphones terminal. For information on how to clean, see the instruction manual attached to the headphones. Otherwise, verify that the cord of the headphones is not broken or damaged.

Sound Quality

The sound quality becomes stable 10 to 30 minutes after the power is turned on. Using cable ties to bundle audio cables with speaker cables may degrade the audio performance, so don’t do this.

CD

Sound skips.

The unit absorbed some vibration, or the disc is scratched or dirty.

Track numbers cannot be stored when setting MEMORY playback.

Make sure that the disc has been loaded, and the track(s) you try to program are included on the disc.
