These limits are designed to provide reasonable protection 

against harmful interference in a residential installation. This 

device generates, uses, and can radiate radio frequency energy

tions, may cause harmful interference to radio communications. 

However, there is no guarantee that interference will not occur 

in a particular installation. If this device does cause harmful 

interference to radio or television reception, which can be deter-

mined by turning the device 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 device and receiver. 

• Connect the device into an outlet on a circuit different 

from that to which the receiver is connected. 

• Consult the dealer or an experienced radio/television 

technician for help.

All connections to other computing devices must be 

made using shielded cables to maintain compliance with 

FCC regulations. 

Changes or modifications not expressly approved by the
