Solution
Turn the VOLUME knob on the right speaker until you hear a click sound. An
LED will light next to the knob when the power is ON.
Check to see if the "Power On" LED is illuminated on the right satellite. If not,
connect the AC power cord.
If the 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 wall outlet
is working.
Verify the AC power cord is plugged into the wall outlet.
Turn the VOLUME knob on the right speaker until you hear a click sound.
An LED will light next to the knob when the power is ON.
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.
Check plug connections on the audio source. Make sure the signal cables are
inserted firmly into the correct jacks.
Make sure the 3.5mm stereo cable is connected and fully inserted into the
"line-out," "audio-out," or the headphone jack of the audio source.
Test the speakers on another audio device. Remove the 3.5mm stereo cable
from the audio source device and connect it to "line-out," "audio-out," or the
headphone jack of another audio source.
Check all cables. Make sure they are connected to "line-out" or "audio-out"
jack on your sound card or other audio source — NOT "speaker-out."
Check the computer operating system volume level and decrease it if necessary.
Unplug the stereo cable from the audio source. Then plug it into the
headphone jack of an alternate audio source (e.g., Walkman, Discman or
FM radio).
Turn the VOLUME knob counterclockwise to lower the volume.
Adjust the computer operating system volume and balance levels to the
center as a starting point, then adjust the level on the speaker using the
volume control.
WAV files are often of poor quality. So distortion and noise are easily noticed
with high-powered speakers. Try a different sound source such as a music CD.
Move your speakers until the interference goes away.
