Abstract
In response to the resetting of a timer , a received electric field level measuring unit measures the received electric field level in a predetermined time, and a control unit computes the average level Vav in that time and compares this level Vav with a threshold level Vth. The unit then computes a cycle period Tav of generation of levels in excess of the threshold level Vth in a predetermined time, and compares this cycle period Tav with a threshold cycle period Tth for high speed movement judgment as set in a memory . When Tav is shorter than Tth, the unit judges and recognizes that the telephone set is in high speed movement, so that it can give an alarm to the person carying the telephone is set while at the same time changing the received sound level or automatically informing that the telephone set is in high speed movement.
