Troubleshooting
If you have any trouble using the CD receiver, look for a solution in this section.
Can’t turn on the CD receiver.
• Make sure that the power cord is properly plugged into the wall outlet (see page 16).
• Make sure that the power cord is properly plugged into the CD receiver’s AC INLET (see page 16).
• Unplug the power cord from the wall outlet, wait 5 minutes or more, then plug it in again.
The CD receiver turns off unexpectedly.
• If the sleep timer has been set and the SLEEP indicator is shown on the display, the CD receiver will turn off
automatically after a specified period (see page 31).
• The CD receiver will automatically enter standby mode when Auto Standby has been set and launches (see
page 17).
The remote controller doesn’t work properly.
• Replace the battery with a new one.
• 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 tinted glass doors of an audio rack or cabinet.
There’s no sound.
• Make sure the CD receiver’s volume is not set too low (see page 17).
• Make sure the correct input source is selected (see page 17).
• Make sure the CD receiver is not muted (see page 17).
• Check all connections and correct as necessary (see pages 14 to 16).
• While headphones are connected, the speakers output no sound (see page 17).
• If there’s no sound from an external device connected to LINE IN, check whether the external device’s audio
output level (volume) might be too low.
The sound quality is not good.
• Make sure the speaker cables are connected with the correct polarity (see page 15).
• Make sure all audio connecting plugs are pushed in all the way (see page 16).
• 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.

Resetting the CD receiver
If you can’t resolve the issue yourself, try resetting the CD receiver before
contacting your Onkyo dealer.
To reset the receiver to its factory defaults, turn it off and, while holding down
the CD receiver’s [ ] button, press the [
] button for more than two seconds.
When the display indicates “Reset”, release the buttons. After a while, the CD
receiver will enter standby mode.
Note that resetting the CD receiver will delete your radio presets and custom
settings (excluding the Bluetooth pairing information).
