FCC (United States) certification  

 

5.2.1

 

STM 320U FCC APPROVAL  

 

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 opera-

tion.  
 
IMPORTANT! Any changes or modifications not expressly approved by the party responsible 

for compliance could void the user’s authority to operate this equipment.  
 

The  Original  Equipment  Manufacturer  (OEM)  must  ensure  that  FCC  labeling  requirements 

are met. This includes a clearly visible label on the outside of the final product. Attaching a 

label to a removable portion of the final product, such as a battery cover, is not permitted. 

The label must include the following text:

 

 

STM 320U 

 

Contains FCC ID: SZV-STM320U  

The enclosed device complies with Part 15 of the FCC Rules. Operation is subject to 

the following two conditions: (i.) this device may not cause harmful interference and 

(ii.)  this  device  must  accept  any  interference  received,  including  interference  that 

may cause undesired operation. 

 
When the device is so small or for such use that it is not practicable to place the statement 
above on it, the information required by this paragraph shall be placed in a prominent loca-
tion in the instruction manual or pamphlet supplied to the user or, alternatively, shall be 
placed on the container in which the device is marketed. However, the FCC identifier or the 
unique identifier, as appropriate, must be displayed on the device.
