ABSTRACT:
The invention relates to the simultaneous operation of items of electrical apparatus, such as but not exclusively, a broadcast data receiver and a DECT telephone system. A problem with this type of apparatus is that the operating frequencies of the same can overlap and in turn cause interference in the operation of the respective items. The invention provides a method for identifying the overlap of the RF ranges of the apparatus, and having identified the same, adjusting the operating characteristics of one of the items to allow the interference to be avoided or minimized and the opportunity for the items of apparatus to be combined into one unit.
