When you click the ECRI button to look up an ECRI Institute Sourcebase manufacturer or UMDNS device code, you are presented with the Code Lookup screen. There are three ways to use this screen: search by UMDNS Code, Manufacturer Code, or Keyword.
If you choose to search by a UMDNS Code or Manufacturer Code, you must enter the complete code in the Search field. Wildcards and partial code searches are not supported for either of these options. If you want to search in that fashion, you must select Keyword(s) in the Search by dropdown.
