Troubleshooting—Continued
The sound quality is not good.
• Make sure the speaker cables are connected with the correct polarity (see page 19).
• 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 stereo receiver.
• If you have any devices that emit high-intensity radio waves near the stereo receiver, such as a cellular phone that's
being used to make a call, the stereo receiver may output noise.
• The stereo 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 stereo receiver is subjected to vibration.
• The stereo 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.
• The headphone output no sound when it is connected with the iPod.
Audio performance
• Audio performance will be at its best about 10 to 30 minutes after the stereo 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.
