When stealth can make the world of difference to the success of an operation, the SRC3300 is the covert TETRA hand-held radio of choice. Small, light and with no display, sounds or interface to betray its presence, the SRC3300 is the world’s best-selling TETRA terminal for covert operations.Worn on the body, with a small remote control unit that fits in the palm, the SRC3300 is incredibly discreet and permits unobtrusive, voiceless signalling through tone generation.The SRC3300 also features tamper-proof security processors, a configurable soft key that can quickly delete sensitive information, and an emergency alarm which enables GPS position and open mic facilities.
