• This product's AC adapter is equipped with a three-wire grounded plug.
The plug only fits in a grounded power outlet. Make sure the power outlet
is properly grounded before inserting the AC adapter plug. Do not insert
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.
• The system can be powered using a wide range of voltages: 100 to 120 or
220 to 240 V AC. The power cord included with the system meets the
requirements for use in the country/region where the system was
purchased. Power cords for use in other countries/regions must meet the
requirements for that country/region. For more information on power cord
requirements, contact an authorized reseller or service provider.
