ABSTRACT:
A wireless keyboard has a transmitting and receiving portion12for transmitting an input data D to an information processing device2and receiving a reception level from the information processing device2, a transmission level setting portion14for storing the transmission level of the input data D, setting a new transmission level referring to the transmission level setting table in response to the combination of the stored transmission level and the reception level on receiving the reception level and detecting a distance information with respect to the information processing device2referring to a distance information table, a transmission level switching portion15for switching the transmission level of the input data D to a new transmission level, an LCD indicating portion16for receiving and indicating the distance information, a timer13for output a time-out signal in the event the reception level is not transmitted even a fixed period of time passed after the input data D is transmitted and an indication LED17for indicating the communications failure by receiving the above-mentioned time-out signal.
