According to the FCC Regulation and Guidance (KDB Publication 784748 D01 v09r01) allows for the FCC ID to be moved to the User’s manual 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 (FCC ID:2ADM5-EP-0619 ) to be printed. The FCC ID will be moved to the last page of user’s manual and charging case. The details are as below: A. Side surface (A): The curvature shape of the silicone sleeve back cover is not flat, so it’s hard to affix thelabel on the surface of the earbuds. B. Top cover (B): The plastic logo of 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 samll 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 Sincerely Yours, Signature: Printed Name: Akshay P Butani Title: Vice President

Circuit Description The 24MHZ crystal oscillator drives the base of Y1. The modulation provided by AC6969(U1). The output of AC6969 module (U1)has the matching network consisting that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 2.4GHz PCBantenna There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3.7 Volt primary battery Feature: Frequency Range: 2402MHz-2480MHz Modulation Type: GFSK, π /4-DQPSK, 8DPSK Antenna Type: PCBA ntenna Crystal: 24MHz
