(1) Note. For classification in this subclass there must be visible indicia or audible signal of some type. As to visual indicia there must be graduations, numbers, or markings to relate a condition. Counting devices which do not supply a visual or audible indication of the count are not proper for this subclass. A mere transparent viewing means is not considered to be a display device for this subclass.
