2.4 equipment for use in Australia should be marked with the C-Tick marking somewhere. My DX7 has it, cant say where as I am at work now.

"The M.A.A.A. does not require that any additional testing is undertaken on approved equipment. However to ensure compliance with the Class Licence and the Australian Radiocommunications Standards the equipment shall be identified as being traceable to those Standards by the application of an Australian “C Tick”. The “C-Tick” is a logo attached to the equipment that shows that the supplier takes the responsibility for compliance with, and traceability to, the Standards."
