FCC Information 

 

This device complies with part 15 of the FCC Results. Operation is subject to the following two conditions : 
 

(1) This Device may not cause harmful interface, and  

 

(2) This device must accept any interference received, including interference that  

 

   may cause undesired operation.  

 
Note: This equipment has been tested and found to comply with the limits for CLASS B digital device, pursuant 
to Part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful 
interference when the equipment is operated in a commercial environment 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 correct 
the interference by one or more of the following measures:  
 1.1. Reorient or relocate the receiving antenna. 
1.2. Increase the separation between the equipment and receiver. 
1.3. Connect the equipment into an outlet on a circuit different from that to which receiver is connected. 
1.4. Consult the dealer or experienced radio/TV technician for help. 
 

WARNING

 

Changes or modifications not expressly approved by the manufacturer could void the user’s authority to 
operate the equipment. 
  
“CAUTION : Exposure to Radio Frequency Radiation. 
Antenna shall be mounted in such a manner to minimize the potential for human contact during normal 
operation. The antenna should not be contacted during operation to avoid the possibility of exceeding the FCC 
radio frequency exposure limit.

following two conditions: (1) this device may not cause interference, and (2) this device must accept any 
interference, including interference that may cause undesired operation of the device. 
  
Cet appareil est conforme avec Industrie Canada RSS standard exempts de licence(s), Son utilisation est 
soumise à Les deux conditions suivantes: (1) cet appareil ne peut pas provoquer d

interférences et (2) cet 

appareil doit accepter Toute interférence, y compris les interférences qui peuvent causer un mauvais 
fonctionnement du dispositif. 
 

Information for OEM Integrator 

 

This device is intended only for OEM integrators under the following conditions: 
1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 
2) The transmitter module may not be co-located with any other transmitter or antenna.  
  
End product labelling 
The label for end product must include  
“Contains FCC ID: YZP-TWFMK305D, Contains IC: 7414C-TWFMK305D”. 
  
“ CAUTION: Exposure to Radio Frequency Radiation.  
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This 
equipment should be installed and operated with minimum distance of 20cm between the radiator and your 
body. This transmitter module is authorized only for use in device where the antenna may be installed such that 
20 cm may be maintained between the antenna and users.”
