PURPOSE:To economically determine the arrival range of a radio wave through easy operation in consideration of not only a speaking channel, but also a control channel as to the radio wave arrival range measuring method of a multi-zone cordless telephone set. CONSTITUTION:The reception intensity of a speaking channel radio wave is obtained as an index within a range of communication between a master equipment and a slave equipment through a control channel and a master equipment 1M for radio wave measuring use equipped with a radio wave intensity measuring means 101 and a radio wave intensity informing means 102 is installed; and a slave equipment 2M for radio wave measuring use equipped with a radio wave intensity display means 201 is moved on the periphery of the master equipment 1M to send the radio wave for the speaking channel, and the radio wave intensity measuring means 101 measures the reception intensity of the radio wave. Further, the radio wave intensity informing means 102 informs the slave equipment 2M of the measurement result which is displayed on the radio wave intensity display means 201 by the slave equipment 2M and compared with the index to determine the radio wave arrival range. |
