the instructions below:  
Fo r t h e a p p lia n ce w it h a p o la rize d AC p o w e r co rd p lu g :  
This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to  
insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact  
your electrician to have a suitable outlet installed. Do not defeat the safety purpose of the polarized  
plug by forcing it in.  
This equipment has been tested and found to  
comply with the limits for a Class B digital device,  
pursuant to Part 15 of the FCC Rules. These limits  
are designed to provide reasonable protection  
against harmful interference in a residential  
installation. This equipment generates, uses, and  
can radiate radio frequency energy and, if not  
installed and used in accordance with the  
instructions, may cause harmful interference to  
radio communications. However, there is no  
guarantee that interference will not occur in a  
particular installation. If this equipment does cause  
harmful interference to radio or television  
reception, which can be determined by turning the  
equipment off and on, the user is encouraged to try  
to correct the interference by one or more of the  
following measures:
