At the top right corner of the Turbo.264 HD window there is a circular gauge. It will be red, and will point at "off", if the Turbo.264 HD hardware is not connected. It will be black, and will point at "on", if the Turbo.264 HD hardware is connected.
The Turbo.264 HD icon in the Dock will also use these gauges to reflect the status of the device.
