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         Yes. The client device is placed directly in contact
the transmitter.                                             with the transmitter.

(5) Mobile exposure conditions only (portable                Yes. Mobile exposure condition apply.
exposure conditions are not covered by this
exclusion).

(6) The aggregate H-field strengths at 15 cm                 Yes. The worst case aggregate fields at 15cm from
surrounding the device and 20 cm above the top               the device is 1.78% of the FCC H field limit.

5. EQUIPMENT UNDER TEST
   5.1.          DESCRIPTION OF EUT
The EUT is a magnetic charging cable which has a single inductive charging coil to charge
Apple Watch. The charging frequency is 326.5 kHz, and the maximum power consumption is
5W in charging status.


   5.2.          WORST-CASE CONFIGURATION AND MODE
The EUT is a single frequency magnetic charger enclosed in stainless steel case with 1 meter
cable length USB-A type. For operation mode, it was tested with model A2095, a big watch.
A2095 was chosen to test as the worst case condition since it has max load overall.

Config          Mode                                               Descriptions

MEASUREMENT SETUP

The measurement was taken using a probe placed 15 cm surrounding the device and 20 cm
above the top surface of the EUT. Measurements were taken from the top and all sides of the
EUT per KDB680106 D01 v03.
