FIELD: physics, signalling.
SUBSTANCE: invention relates to alerting ambulance service and rescue service in case of emergency by a user in possession of a personal radio-signal module. Described is a radio-module which has a power supply, a power-on button and a power supply charge indicator, an alarm signal button, a main radio channel which has a carrier-frequency generator and a power amplifier, as well as a programmer connected to the control input of the power amplifier for generating pulsed signal packets with discrete power variation, with reduction from a maximum to a set minimum value, as well as combined with constant power signals. Also disclosed is a method for personal signaling on the personal radio-module and a system for signaling for help using the said radio-module.
EFFECT: increased accuracy of locating the radio-module.
