FCC Regulatory Information 
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. 
FCC WARNING: 
Change or modifications not expressly approved by the party responsible for compliance 
could void the user’s authority to operate the equipment. 
RF exposure compliance: 
This module has very low levels of RF energy that it deemed to comply without 
maximum permissive exposure evaluation (MPE). 
But it is desirable that it should be installed and operated with at least 20cm and more 
between the radiator and person’s body (excluding extremities: hands, wrists, feet and 
legs). 
FCC 15.19(3) required 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. 
IC(Industry of Canada) Regulatory Information  
“Operation is subject to the following two conditions: (1) this device may not cause         
interference, and (2) this device must accept any interference received, including 
interference that may cause undesired operation of the device.” 
“To reduce potential radio interference to other users, the antenna type and its gain 
should be so chosen that the equivalent isotropically radiated power (EIRP) is not more 
than that required for successful communication.” 
RF Exposure Statement: 
“The installer of this radio equipment must ensure that the antenna is located or 
pointed such that it does not emit RF field in excess of Health Canada limits for the 
general population; consult Safety Code 6, obtainable from Health Canada’s website 
www.hc-sc-gc.ca/rpb” 
ICES-003 Statement: 
This Class B digital apparatus complies with Canadian ICES-003. 
Cet apparei numérique de la class B est conforme à la norme NMB-003 du Canada.
