When a radar signal is received from a ship or aircraft, the S4 Rescue automatically transmits a response signal, which clearly identifies the survival craft on the radar screen by means of a
stream of 12 in-line dots. Once activated, the S4 will remain in standby mode for over 96 hours.
The S4 Rescue has been designed for reliable operation in the toughest of marine environments.
