TROUBLESHOOTING
Possible Cause
The component is plugged into a switched
outlet and the PowerSource has not been
turned On.
The PowerSource is plugged into a Switched
outlet, but power on the component is not On.
In some instances, a component plugged
into a switched outlet won't receive power
when the PowerSource is turned On unless
the component power is also switched On.
The PowerSource is sharing AC power with
equipment that is not properly grounded.
Remedy
• Turn the PowerSource On.
• Or, plug the component in to an
Unswitched outlet.
• Turn the component power On.
• Connect your PowerSource
to a dedicated outlet.
• Try unplugging different components
from the PowerSource one at a time
to see if the noise stops. If a
component is discovered to be
improperly grounded, attach a copper
wire from the component's chassis to
the PowerSource's grounding post.
