the plug into a non-grounded power outlet. Contact your electrician for 
details.

Warning! The grounding pin is a safety feature. Using a power 
outlet that is not properly grounded may result in electric shock 
and/or injury.

Note: The grounding pin also provides good protection from 
unexpected noise produced by other nearby electrical devices that 
may interfere with the performance of this product.
