Amendment: This device complies with Part 15 of the FCC Rules 

and with Industry Canada license-exempt RSS standard(s). 

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. Changes or modifications

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 instal-

lation. 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 interfer-

ence 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.
