7. Essential performance
Unless operated by the chair control switch, the chair will not make any movements. Unless operated by the
foot controller, the handpiece will not move except for sounding a buzzer and switching the indicator on/off.
Loss or decline of essential performance may cause the chair or handpiece to move unexpectedly, causing
harm to the patient, operator or people or objects around the patient or operator.
