TROUBLE SHOOTING GUIDE
No Sound from Any Speakers?
Is there Power to your System?
Ensure that your subwoofer is plugged securely into a working AC wall outlet and that the blue power
indicator LED is ON.
Are your Volume Controls adjusted correctly?
Ensure your computer's internal volume settings are set to mid-level, and the Volume of the Controller
Satellite (Left) is adjusted correctly.
Is the Mute on your System set to Auto-Protect Mute or to ON?
Mute on is ON when both the + and - Volume buttons are depressed, and OFF when they are both
depressed again. Please check the blue status LED on the subwoofer. A non-pulsing effect indicates
the Mute is in Off mode.
Are your Cables properly connected?
Check all the connections are secure.
Are you receiving an Audio Signal?
Please try connecting your speakers to an alternate audio source, such as another portable CD player
or Discman to determine that your speakers are working.
Sound from only part of your system?
Please ensure the "S" plug connecting the satellites, is firmly inserted into the socket assembly on the
subwoofer mounting base. Try substituting the audio connection to another source, e.g. a Discman,
portable radio etc. If the system now works, the original source is at fault.
When playing CD from computer, only one Speaker has sound
Mostly this phenomenon tends to occur with a new computer - only one satellite works when playing an
audio CD, but all work correctly when running a WAV file or playing a Game. The reason for this is the
CD-ROM is not matched with the Soundcard, or one signal channel maybe shorted to a ground wire.
Also please refer to the CD-ROM user manual to adjust the jumpers.
