Federal Communications Commission Interference Statement (for U.S.A.)

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 rea-

sonable protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not in-

stalled 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 re-

ceiver is connected.

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

Compliance Information Statement (for U.S.A.)

This device,  complies with part 15 of the FCC Rules. Operation is subject to the follow-

ing 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. 
(3) This module meets the requirements for a mobile device that may be used at separa-

tion distances of more than 20cm from human body. To meet the RF exposure require-

ments of the FCC this device shall not be co-located with another transmitting device.  
The responsible party for the compliance of this device is:

Any changes or modifications not expressly approved by the grantee of this device could 

void the user’s authority to operate the equipment.

Exposure to Radio Frequency Radiation

To comply with FCC RF exposure compliance requirements, a separation distance of at 

least 20 cm must be maintained between the antenna of this device and all persons. This de-

vice must not be located or operating in conjunction with any other antenna or transmitter.
