Troubleshooting
If you have any trouble using the CBX-300, look for a solution in this section.
If you can't resolve the issue yourself, try resetting the CBX-300 before contacting your Onkyo dealer.
To reset the CBX-300 to its factory defaults, unplug the power
cord, and while holding down the CBX-300's [STANDBY/ON] but-
ton, plug the power cord back into the wall outlet. "RESET" will
appear on the display and the CBX-300 will enter Standby mode.
Note that resetting the CBX-300 will delete your radio presets and custom settings.

ically after a specified period (see page 47).

The sound quality is not good.
• Make sure all audio connecting plugs are pushed in all the way (see page 18).
• The sound quality can be affected by strong magnetic fields, such as that from a TV. Try moving any such devices
away from the CBX-300.

used to make a call, the CBX-300 may output noise.
• The CBX-300'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.

• The CBX-300 is not a portable device. Use it in a location that's not subject to shock or vibration.

• 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.
