  • Page 12: During Use

    SAFETY PRECAUTIONS: Usage Precautions During use CAUTION • Before use, perform visual and operation checks. If abnormal conditions are encountered, stop using the system. If the system is used under abnormal conditions, intended results may not be achieved. Also unantici- pated malfunctions or health hazards may occur due to improper diagnosis.
  • Page 13 SAFETY PRECAUTIONS: Usage Precautions CAUTION • Equipment connected to the analog or digital interfaces must be certified according to the applicable international standards for safety (such as EN 60601-1 and IEC 60601-1). Furthermore, all configu- rations shall comply with the system standard IEC 60601-1. Anyone who connects additional equip- ment to the signal input part or signal output part configures a medical system, and is therefore responsible that the system complies with the requirements of the system standard IEC 60601-1.
