FCC ANd OTHEr iNFOrmATiON

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. Operation is subject to the following two conditions:
1.  This device may not cause harmful interference, and
2.   This device must accept any interference received, including  

interference that may cause undesired operation.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. Some 
equipment operates at frequencies that may cause interference to nearby TVs and VCRs; to minimize or prevent such 
interference, the system base should not be placed near or on top of a TV, PC monitor, or VCR; and, if interference is  
experienced, moving the desk station farther away from the TV or VCR will often reduce or eliminate the interference.
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 system off and on, the user  
is encouraged to try to correct the interference by one or more of the following measures: 
1.  Increase the separation between the equipment and receiver.
2.  Consult the dealer or an experienced radio TV technician for help.
