1. Turn o the power to the device.
2. Now press the "SELECT/SET" button and reconnect the power to the device while holding
down the button.
3. Hold down the button until the red error LED "F" stops ashing and is permanently lit.
4. Now release the button and wait until the fault LED "F" goes o again.
5. The device starts automatically with the factory defaults.
