FCC Statement 

This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) thi 
s device may not cause harmful interference, and (2) this device must accept any interference received, incl 
uding interference that may cause undesired operation. 
Changes or modifications not expressly approved by the party responsible for compliance could void the us

er’ 

s authority to operate the equipment. 
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursua 
nt to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful inte 
rference in a residential installation. This equipment generates uses and can radiate radio frequency energy a 
nd, if not installed and used in accordance with the instructions, may cause harmful interference to radio com 
munications. 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 turn 
ing 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 important announcement 

Important Note: 

Radiation Exposure Statement 

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This 
equipment should be installed and operated with minimum distance 0cm between the radiator and your 
body. 
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 
Country Code selection feature to be disabled for products marketed to the US/Canada. 
This device is intended only for OEM integrators under the following conditions: 

1.

 

The antenna must be installed such that 0 cm is maintained between the antenna and users, and 

2.

 

The transmitter module may not be co-located with any other transmitter or antenna, 

As long as the three conditions above are met, further transmitter testing will not be required. However, the 
OEM integrator is still responsible for testing their end-product for any additional compliance requirements 
required with this module installed. 

 

Important Note: 

In  the event  that  these  conditions  cannot  be  met  (for example  certain laptop configurations  or  co-location 
with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot be 
used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the 
end product (including the transmitter) and obtaining a separate FCC authorization. 

 

End Product Labeling 

The final end product must be labeled in a visible area with the following" Contains FCC ID: 

2A4TN-FN-RFID-

RC522

 

Manual Information to the End User 

The OEM integrator has to be aware not to provide information to the end user regarding how to install or 

remove this RF module in the user’s manual of the end product which integrates this module.

 

The end user manual shall include all required regulatory information/warning as show in this manual.
