Remark: The device meets the mobile RF exposure limit at a 15cm separation distance as specified
in §2.1091 of the FCC Rules and meeting all of the following requirements as follows:
(1) Power transfer frequency is less than 1 MHz.
(2) Output power from each primary coil is less than or equal to 15 watts.
(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.
(4) Client device is placed directly in contact with the transmitter.
(5) Mobile exposure conditions only (portable exposure conditions are not covered by this exclusion).
(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.
