interference.
SOLUTION
Press Power button on the right speaker.
Check to see if the power on LED is illuminated on the right satellite. If not,
connect AC power.
If the satellite's AC power cord is plugged into a surge protector, make sure
the surge protector is switched on.
Plug another device into the wall outlet (same jack) to verify the outlet is working.
Verify the satellite's AC power cord is plugged into the wall outlet.
Verify the Power button has been pressed and the green LED is illuminated.
Turn the volume knob clockwise to raise the volume.
Check volume level on the computer sound card or alternate audio source
device and set at mid-level.
Connect audio cable to the audio source. Make sure the signal cables are
inserted firmly into the correct jacks.
Make sure the lime green 3.5 mm stereo cable is connected and fully inserted
in the "line-out" or "audio-out" jack on your sound card or other audio source.
Test the speakers on another audio source by removing the lime green 3.5 mm
cable from the audio source and connecting it to the "line-out" or headphone
jack of a different audio source (e.g., portable CD, cassette player or FM radio).
Check all cables. Make sure they are connected to "line-out" or "audio-out"
jack on your sound card or other audio source—and NOT "speaker-out."
Check the Windows volume control and decrease if necessary.
Unplug the lime green 3.5 mm stereo cable from the audio source. Then plug it into
the headphone jack of an alternate source (e.g., Walkman, Discman or FM radio).
Decrease volume level.
Check the Windows volume and decrease if necessary.
.WAV and .MID files are often of poor quality; therefore distortion and noise are
easily noticed with high-powered speakers. Try a different audio source such as
a music CD.
Move your speakers to see if the interference goes away. You may be able to
purchase a shielded cable at your local electronics store.
