FCC Caution: 

Any Changes or modifications not expressly approved by the party responsible for 
compliance could void the user's authority to operate the equipment.  

 

This device complies with 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.   

 

IMPORTANT NOTE:   

Note: 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:   

Reorient or relocate the receiving antenna.   

Increase the separation between the equipment and receiver.   

Connect the equipment into an outlet on a circuit different from that to which the receiver 

is connected.   

Consult the dealer or an experienced radio/TV technician for help.  

 

FCC Radiation Exposure Statement:   

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled 
environment .This equipment should be installed and operated with minimum distance 20cm 
between the radiator& your body.
