Immersion Levels 
  Caution: To avoid damage to the transducer, observe the immersion levels indicated for each 
transducer type. 
  Caution: Do not immerse the label located on the cable of the CW transducer. 
Note: Transducers meet Ingress Protection level IPX8 of EN 60529 and IEC 60529 to the depth of 
the immersion line shown in the illustration. Endocavity transducers exceed minimum Ingress 
Protection level IPX7 of IEC 60601-2-18 to the depth of the immersion line shown in the illustration. 
Note: Intraoperative transducers are immersible up to the strain relief on the connector.
