Pontiac Trail, Commerce Township, Michigan, 48390, United States Email: [email protected] Tel: 2488633001Extension:1390 Fax: 2488633000 FCC ID Cover Letter We, FKA Distributing Co., LLC, hereby submit justification for placing the FCC ID in the associated user manual and charging case. According to the FCC Regulation and Guidance (KDB Publication 784748 D01 v09r01) allows for the FCC ID to be moved to the user manual and charging case if the device is unquestionably too small for the FCC ID to be printed. Referring to the above quote, as the device is too small for the label (FCC ID: TG3-HXEP525L) to be printed. The FCC ID will be moved to user manual and charging case. The details are as below: A. Side surface (A): The side surface does not provide enough physical space to fit the printing of the FCC ID according to below reference picture. B. Top cover (B): The top cover does not provide enough physical space to fit the printing of the FCC ID according to below reference picture. Conclusion: Based on the above description of area A to B, we conclude that the device is unquestionably too small for enabling the FCC ID to be printed onto any surface. We therefore request to move the FCC ID to the user manual and charging case. Best regards, Mark Straight Senior Project Engineer
