Troubleshooting
When first installing a new system some simple
instructions may be overlooked which can cause the
unit to be inoperative. Please make the following
checks:
• Make sure all connecting plugs between the satellite
speakers, subwoofer (if applicable) and computer are
fully seated.
• Make sure the wall power outlet or power strip has
power. The outlet can be checked with a lamp or
some other appliance. If the power strip has a switch
make sure it is turned on.
• Make sure the power switches on the satellites and
subwoofer (if applicable) are turned on.
• It is possible to test the unit by pulling out the audio
cable that is connected to the computer and
connecting it to an alternate audio source such as a
portable CD player.
• When the unit is operative, vibrations from the
speaker sound can cause other loose objects to
vibrate. These extraneous vibrations may lead
to the erroneous conclusion that the speakers are
defective. In most instances, removing the vibrating
object cures the problem.
