DANGER
	UNINTENDED EQUIPMENT OPERATION A constantly lit FS-STATUS LED indicates a possible safety-related system error. It is your responsibility to ensure that all necessary repair measures are initiated after an error occurs since subsequent errors can result in dangerous situations! Failure to follow these instructions will result in death or serious injury.
