Hello all, The company I work for has an old Aurical system.The details are attached below. It's been several years since it was looked at and the person who was handling it has left. There is no accompanying software that I can find to make it measure an audiogram. What am I looking for and where can i find it? Any help is appreciated. Thanks, Mina Aurical EN 60645-1, -2 type:2, A Part no: 8-03-650
