Operating frequency is 111 – 129 kHz (2) Output power from each primary coil is less than or equal to 15 watts. Maximum rated charging power is 15W. (3) The transfer system includes only single primary and secondary 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 device only has a single coil capable of coupling to a single secondary coil in the client device. (4) Client device is placed directly in contact with the transmitter. The client device has to be placed directly in contact with the charger. (5) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion). This device must be powered to operate and therefore is considered a mobile charger, not a portable charger. (6) The aggregate H-field strengths at 15 cm surrounding the device and 20 cm above the top surface from all simultaneous transmitting coils are demonstrated to be less than 50% of the MPE limit. The highest measured H field was 0.1499 A/m which is 9.2 % of the limit.
