This device complies with Part 15 of FCC rules. Moduification of this device without the express consent of the 
manufacturer may invalidate the user's right to operate the device.
This device complies with Part 15 of the FCC Rules subject to the following two conditions:
1) This device must not cause harmful interference and,
2) This device must accept all interference, including interference that may cause undesired operation.
RF Exposure Warning: A minimum separation distance must be maintained between the user and the radiating 
antenna. Failure to maintain this minimum separation distance may cause the device to operate in excess of the rf 
exposure levels required by FCC Rules and should be avoided.
