ABSTRACT:
A rescue aiding apparatus carried by a lost person includes a radio receiver for receiving a radio signal, a radio transmitter for transmitting a radio signal, and a power supply for supplying working power. When the radio receiver receives a radio search signal transmitted from a search party, the power supply supplies operating power to the radio transmitter. The apparatus thereby becomes fully operable, and the radio transmitter transmits a radio signal as a response signal for enabling a search for the lost person needing protection. Even when the lost person is unable to make a rescue request, the search party can, on their own will, place the rescue aiding apparatus carried by the lost person in a fully operable state to notify the search party of a current position of the lost person.
