20090233641 | RADIO COMMUNICATION DEVICE - A radio communication device that outputs an alarm when a reception level of a radio wave from a wireless unit is less than a threshold value, includes a reception level measuring section for measuring the reception level of the radio wave transmitted from the wireless unit at certain times. A threshold value setting section for setting a first threshold value or a second threshold value less than the first threshold value based on a difference between the reception level of the radio wave measured a previous time and the reception level of the radio wave measured a subsequent time. An alarm output requesting section for causing an alarm output section to output an alarm if the reception level of the radio wave measured a subsequent time is less than the first threshold value or the second threshold value. | 09-17-2009 |
