To keep you safe, a beeping alarm alerts you when the unit detects a voltage, enabling you to work out when a circuit is live and when wiring is hazardous.

The RCD button enables you to test sockets with integrated residual current devices. A quick press of the button should trip the RCD, so you know it's working correctly. RCD sockets add an extra layer of electrical protection. You'll find them in workshops where there are power tools and in setups with heavily used appliances.
