A number of main groups in this sub-class contain a large number of older documents that were classified administratively. These documents have not yet been reclassified to the sub-groups and are indexed with E05Y 2800/00. This index should not be used for classification.
E05F 2700/00 is an old indexing scheme. It can be used for search but should not be used for classification.
Under E05Y 2900/00 and lower an indexing scheme exists for information on the application or use of the devices. The indexing scheme is shared with the sub-class E05D. It is mandatory to allocate the appropriate indexing code of E05Y 2900/00, if the application or use is not implicit from the classification titles.
