FCC Compliance Statement: 
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. This device must accept any interference received, including 
interference that may cause undesired operation. Product that is a radio transmitter is 
labeled with FCC 
ID. 
FCC Caution: 
 (1) Any changes or modifications not expressly approved by the grantee of this device 
could void the user's authority to operate the equipment. 
 (2) The modules FCC ID is not visible when installed in the host, or 
 (3) If the host is marketed so that end users do not have straight forward commonly used 
methods for access to remove the module so that the FCC ID of the module is visible; then 
an additional permanent label referring to the enclosed module: Contains Transmitter 
Module FCC ID: AK81492549 or Contains FCC ID: AK81492549 must be used.  
 (4) This equipment must be installed and operated in accordance with provided 
instructions and the antenna(s) used for this transmitter must be installed to provide a 
separation distance of at least 20 cm from all persons and must not be co-located or 
operating in conjunction with any other antenna or transmitter. End-users and installers 
must be provided with antenna installation instructions and transmitter operating conditions 
for satisfying RF exposure compliance. 
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.
