Troubleshooting

If you have any trouble using the CD receiver, look for a solution in this section.

If you can’t resolve the issue yourself, try resetting the CD receiver before contacting your Onkyo dealer.

To reset the CD receiver to its factory defaults, turn it on and, while holding down the [] button, press the [STANDBY/ON] button.“Clear” will appear on the display and the CD receiver will enter Standby mode.

Note that resetting the CD receiver will delete your radio presets and custom settings.

Power

Can’t turn on the CD receiver.

•Make sure that the power cord is properly plugged into the wall outlet (see page 23).

•Unplug the power cord from the wall outlet, wait 5 seconds or more, then plug it in again.

The CD receiver turns off unexpectedly.

•If the sleep timer has been set and the TIMER indicator is shown on the display, the CD receiver will turn off auto- matically after a specified period.

•When timed playback or recording finishes, the CD receiver automatically switches to Standby mode.

•If the STANDBY indicator is flashing, the built-in amplifier protection circuit has been activated. This can happen if there’s a short between the positive and negative wires of a speaker cable.

Audio

There’s no sound.

•Make sure the CD receiver’s volume control is not set to minimum (see page 25).

•Make sure the correct input source is selected (see page 25).

•Make sure the CD receiver is not muted (see page 26).

•Make sure the speakers are connected correctly (see page 16).

•Check all connections and correct as necessary (see pages 14 to 23).

•While headphones are connected, the speakers output no sound (see page 25).

The sound quality is not good.

•Make sure the speaker cables are connected with the correct polarity (see page 16).

•Make sure all audio connecting plugs are pushed in all the way (see page 17).

•The sound quality can be affected by strong magnetic fields, such as that from a TV. Try moving any such devices away from the CD receiver.

•If you have any devices that emit high-intensity radio waves near the CD receiver, such as a cellular phone that’s being used to make a call, the CD receiver may output noise.

•The CD receiver’s precision drive mechanism may emit a faint hissing sound while reading discs during playback or when searching for tracks. You may be able to hear this noise in extremely quiet environments.

Audio output is intermittent when the CD receiver is subjected to vibration.

• The CD receiver is not a portable device. Use it in a location that’s not subject to shock or vibration.

Headphone output is intermittent or there’s no sound.

•This may be due to dirty contacts. Clean the headphones plug. See your headphones’ instruction manual for cleaning information. Also, make sure that the headphones cable is not broken or damaged.

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 13).
