STANDBY/ON
Power
Can't turn on the CD receiver.
• Make sure that the power cord is properly plugged into the wall outlet (see page 22).
• 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 24).
• Make sure the correct input source is selected (see page 24).
• Make sure the CD receiver is not muted (see page 25).
• Make sure the speakers are connected correctly (see page 18).
• Check all connections and correct as necessary (see pages 16 to 22).
• While headphones are connected, the speakers output no sound (see page 24).
The sound quality is not good.
• Make sure the speaker cables are connected with the correct polarity (see page 18).
• Make sure all audio connecting plugs are pushed in all the way (see page 19).
• 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.
