the equipment, under the normal charging states, LED D4 will be turned on all the time, and LED D3 will be blanking, and the RX will powered on the equipment normally. Figure-3 WCT-15W1COILTX charging the equipment Others Indicates: when the Transmitter get the end power communication information, it will stop the charging and wait until the RX is removed, under this state LED D3 will be turned off, and LED D4 will be turned on all the time.
