Equipment is intended for clinical professionals. For continued safe use of this equipment, it is necessary that the listed instructions are followed. However, instructions listed in this manual in no way supersede established medical practices concerning patient care.

Inspect the sensor for signs of physical damage. Discard a damaged sensor immediately. Never repair a damaged sensor; never use a sensor repaired by others.

Route all cables away from patient’s throat to avoid possible strangulation. Do not touch the patient, table, instruments, modules or the monitor during defibrillation. To avoid the risk of electric shock, this equipment must only be connected to a supply mains with protective earth. Use only approved accessories, including mounts, and defibrillator-proof cables and invasive pressure transducers. For a list of approved accessories, see the supplies and accessories list delivered with the monitor. Other cables, transducers and accessories may cause a safety hazard, damage the equipment or system, result in increased emissions or decreased immunity of the equipment or system or interfere with the measurement. DISCONNECTION FROM MAINS - When disconnecting the system from the power line, remove the plug from the wall outlet first. Then you may disconnect the power cord from
