Compliance 

 

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. 

Changes or modifications not expressly approved by Intellijel Designs, Inc. could 
void the user’s authority to operate the equipment. 

Any digital equipment has been tested and found to comply with the limits for a 
Class A digital device, pursuant to part 15 of the 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 instruction manual, may cause harmful interference to radio 
communications. 

 

 

 

This device meets the requirements of the following standards and directives: 

EMC:  2014/30/EU 
EN55032:2015 ; EN55103-2:2009 (EN55024) ; EN61000-3-2 ; EN61000-3-3  

Low Voltage: 2014/35/EU
