Users Manual

LG Electronics USA. 1000 Sylvan Avenue Englewood Ciliffs, New Jersey, United States Date: Sep 18, 2014 Letter of declaration a) Power transfer frequency is less than 1MHz  The power transfer frequency of DUT(Device Under Test) is between 110KHz and 205KHz. b) Output power from each primary coil is less than 5 watts  Output power from each coils are Max. 5 watts. c) The transfer system includes only single primary and second coils. This includes charging systems that may have multiple primary coils and clients that are able to detect and allow coupling only between individual pairs of coils  The DUT are consist of one charging coil using A11 coil as below, so the DUT can detect and allow coupling only between TX and RX Coil.(A11 coil is only single coil.) d) Client device is inserted in or placed directly in contact with transmitter  When the client device is placed directly in contact with transmitter, then charging is able to start. e) The maximum coupling surface area of the transmit (charging) device is between 60Cm 2 and 400 Cm 2  The Maximum coupling surface area of the charging transmit is 63Cm 2 . Maximum coupling surface area(7.0 Cm X 9.0 Cm) f) Aggregate leakage fields at 10㎠ surrounding the device from all simultaneous transmitting coils are demonstrated to be less than 30% of the MPE limit.  The highest leakage filed is less than 30 % of the MPE limit. Sincerely, Jacob Cho Director, Standards & Compliance
