ABSTRACT:
In a wristwatch type distress message sending device worn by the user, a positional information generator receives GPS signals sent by a plurality of GPS satellites and generates positional information on the latitude and longitude of the position of the user. When the user meets a disaster, a distress message signal generator generates a distress message signal containing the positional information generated by the positional information generator. A sender then sends out the distress message signal by radio.
