ADuM6000 EMI @ 180 MHz

My client is currently using the ADuM6000. Apparently after conducting RF Emission testing @ 360MHz their end product is not passing and they believe they have "pinpointed" the emissions coming from the ADuM6000. They also ordered the ADuM6000 eval board and tested it with a 7mA load and RF emission is the same as their board @ 360 MHz. According to them they have followed AN-0971. Any suggestions or tips would be greatly appreciated. Thanks
