Abstract:
A communications device comprising:a first replaceable unit comprising first memory means for storing first parameter information which defines an operation of the communications device, said first parameter information comprising a transmission frequency and a transmission power level; a second replaceable unit comprising second memory means for storing second parameter information which defines the operation of the communications device, said second parameter information comprising a transmission frequency and a transmission power level; a transmit/receive part for transmitting a signal to a communications medium and receiving a signal therefrom; and control means for determining whether the first parameter information stored in the first memory means coincides with the second parameter information stored in the second memory means and for setting the parameter information in the transmit/receive part so that the transmit/receive part is allowed to perform a transmission operation when the first parameter information stored in the first memory means coincides with the second parameter information stored in the second memory means, wherein each of the first memory means and the second memory means are provided by respective chips.
