Heartbeat LED

The Squing 2 has a 'heartbeat' LED that indicates status, and can be seen at all times and from all angles through a cover lens (no lens in metal housings).

The LED will flash when the Squing 2 is 'off ' and is constantly lit when 'on'. The LED constantly indicates that the Squing 2 is functioning correctly. Different flash rates are used to indicate product malfunction, and gives a local indication of the process state.
