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. 

Key points about Part 15 compliance: 

Unlicensed devices-Most consumer electronics that use radio frequencies, like Wi-Fi enabled devices, Bluetooth devices, and many remote controls, fall under Part 15 regulations as they are considered "unlicensed" radio transmitters.  

Emission limits- Part 15 specifies limits on how much radio frequency energy a device can radiate, ensuring it doesn't interfere with other nearby electronic devices like radios or TVs.  

Why is this important? 

"This device complies with Part 15" means that the electronic device in question meets the standards set by the Federal Communications Commission (FCC) under Part 15 of their regulations, which governs the amount of radio frequency radiation a device can emit and ensures it doesn't cause harmful interference with other electronic devices.   

In the world of electronics manufacturing, designing a quality product is just the start of a complex journey from manufacturer to customer. Not only must manufacturers meet the needs and expectations of their customers, they must also comply with complex regulatory requirements in the country where the product is manufactured, as well as the countries where it will be distributed and sold. 

Safety is at the heart of these regulations. Manufacturers must ensure that their products will not interfere with other wireless devices operating nearby or put the health and safety of people and animals at risk. 

For these reasons, most countries regulate the testing of digital devices, radio-frequency(RF)/radio devices, and products with integrated wireless technologies before they are imported, marketed, and sold. In the United States, the Federal Communications Commission (FCC) governs this important process.
