The ProVES 2011 software was originally tested and certified by HIMSA using Noah version 4.0. With the introduction of Noah 4.1 HIMSA made a slight modification to the way it delivers audiometric data to modules.HIMSA did not expect this change to adversely affect any other software and thus did not communicate the change in advance.HIMSA regrets that this problem occurred and has taken steps to ensure that it does not happen in the future.SeboTek has released a new version ProVES 2011 Build 1026 which provides a solution which will allow users using Noah 4.1 to use ProVES and read audiometric data.Please contact SeboTek for further information on how to obtain this new version.
