Communication devices could be one way (eg. TV, radio), or two way (eg. telephone). Information providing devices could be used in various field of work such as navigational (eg. radar, echo sounder, electronic altimeter, etc.), medical aids (oscilloscopes, graph chart plotters), Lab aids (pH meter, electronic balances, etc.) information technology (computer and hardware), and other fields.RULE ATTR dCHRSRULE ATTR dCHRSRULE ATTRdCHRSRMSTRULEATTR dCHRSLMSTRULEATTR dCHRS
