PROPER GROUNDING AND INSTALLATION
~ WARNING - Proper Grounding
A Monster PowerCenter requires a properly grounded outlet for safety and to protect connected equipment.
If you're not sure if your home's electrical wiring is properly grounded, have it checked by a qualified electrician.
IMPORTANT NOTE - Proper Power and Protection
To completely protect your equipment against electrical surges, every AC power cable and coaxial cable line
in your system must be connected to the PowerCenter.
IMPORTANT NOTE - Proper Protection and the Limited Connected Equipment Warranty
The $250,000 Limited Connected Equipment Warranty becomes invalid if any wire (AC or coax) or audio or video
interconnect leading into the equipment comes from
a
component that is not properly protected by the PowerCenter.
See the Warranty Information section of this owner's manual for important details.
