    Safety and Regulatory Information 1.3 Safety Devices The imaging system has 2 basic types of safety devices: • Emergency Stop Button - used by the operator to halt the motorized system motions in cases where there is any possibility of danger to the patient. CAUTION Do not reset the button until the problem that necessitated its use is resolved.

  • Page 18: Emergency Stop Button

    ™ SPIRIT DH-V Service Manual Nucline 1.3.1 Emergency Stop Button 1.3.1.1 Using the Emergency Stop • Use the emergency stop switches to stop all gantry, detector and imaging table motions in case of emergency. • The Emergency Stop button disconnects power to the motors controlling IMPORTANT movement, and all motions stop quickly.
  • Page 19 Safety and Regulatory Information all gantry motions stop to prevent the hazards of personal injury or equipment damage. However, collisions can occur in spite of this safety feature. Use increased care to prevent collisions in the following cases: • Positioning in MANUAL OVERRIDE mode. Collision detect is disabled when the system is in MANUAL OVERRIDE mode.
