Note ! The transducer is dedicated to one Eclipse only! Calibration is stored on the Eclipse. Replacing the
transducer will require new calibration of the transducer connected to the Eclipse.
The CE-mark indicates that Interacoustics A/S meets the requirements of Annex II of the Medical
Device Directive 93/42/EEC. Approval of the quality system is made by TÜV – identification no.
