  • Page 8: Precautions And Warnings

    Under no circumstances should the D360R-4 Operator simultaneously touch the D360R-4 main unit and the subject. WARNING - The D360R-4 should not be modified as this may present a safety hazard to the subject. Defibrillator Warning The D360R-4 is NOT classified as defibrillator proof and should not be connected to a subject undergoing defibrillation.

  • Page 9: Temperature

    As no parts of the D360R-4 are expected to wear out the only limitation to the service life is likely to be the ongoing ability to replace electronic components that may randomly fail and damage sustained during normal use.
