    2. Inspection before Use Prior to use, the probe and accessories must be carefully inspected so that they are appropriate for use. If you find any damage, do not use them and contact a service support immediately. 2.1 Inspection for Appropriate Connection 1) Confirm that the system is correctly operating.
  • Page 11: Operation Procedure

    The Magnetic sensor attachment and the Spacer for EZU-RV2S are needed for Real-time Virtual Sonography (RVS). Regarding the option for RVS, please refer to “4.Option of EUP-O732T”. 2) It is recommended to use a disposable probe cover for preventing a patient from infection and the probe cover should be allergy free material to avoid allergic reaction.
  • Page 12 6) After the use of the probe, clean and disinfect and sterilize the probe immediately and using RVS, also clean and disinfect and sterilize the Magnetic sensor attachment. In case of using RVS with an EZU-RV2S, also clean and disinfect and sterilize the Spacer for EZU-RV2S.
  • Page 13: Option Of Eup-O732T

    There are two types of the magnetic sensors for EUP-O732T, EZU-RV2S and EZU-RV3S. EZU-RV2S and EZU-RV3S are shown in Fig.3 and Fig.8. The uses of EUP-O732T with wither of the magnetic sensors enables the user to perform RVS (Real-time Virtual Sonography).
  • Page 14 CAUTION 1) Never attach the magnetic sensor attachment to the probe in the incorrect direction, otherwise result false diagnosis. 2) Never forget to attach the Spacer for EZU-RV2S when using RVS with magnetic sensor EZU-RV2S, otherwise it may result in false diagnosis.
