The AlphaShield Home Edition requires a positive polarity to be provided to the center 
conductor of the power plug.  Ensure that the proper adapter plug used is connected to 
provide proper power to the AlphaShield Home Edition device. 
 
You can also obtain a replacement universal power adapter directly from AlphaShield 
Inc.  AlphaShield Inc. will charge an amount of $8.99 U.S. funds for a replacement
