3. Enter the 20-bit security code (without any space charaters) in the popup window then click "CHECK".

4. You will get the checking result if the code is correct.
A. The product you are checking is genuine. The product is manufactured by FiiO Company, thanks for choosing us.
B. The number you are checking does not exist. The product is not manufactured by FiiO Company.
