• To avoid risk of electric shock, the equipment must only be connected to 
mains power with protective earth. If a protective earth conductor is not 
provided, operate it on battery power, if possible. 
• Do not use the multiple portable socket outlets (MPSO) or AC mains 
extension cords. Insure that the sum of the individual ground leakage 
currents does not exceed the allowable limits. 
• Do not touch the patient and live parts simultaneously. Otherwise patient 
injury may result.
• Do not come into contact with the patient during defibrillation. Otherwise 
serious injury or death could result. 
• Do not open the equipment housings. All servicing and future upgrades must 
be carried out by trained and authorized personnel.
• Do not rely exclusively on the audible alarm system for patient monitoring. 
Turning the alarm volume to a low level or off may result in a hazard to the 
patient. Remember that alarm settings should be customized according to 
patient situations. Always keep the patient under close surveillance.
• Physiological data and alarm messages provided by the monitor should not 
be used as the sole basis for diagnosis or therapy decisions. They must be 
used in conjunction with clinical signs and symptoms. Misinterpretation of 
the measured values or other parameters can endanger the patient.
• Do not place the equipment or accessories in any position that might cause it 
to fall on the patient.
• Do not start or operate the equipment unless the setup was verified to be 
correct.
• To avoid inadvertent disconnection, route all cables in a way to prevent a 
stumbling hazard. Wrap and secure excess cabling to reduce risk of 
entanglement by patients or personnel. 
• The equipment should not be used as the sole basis for medical decisions. It 
must be used in conjunction with clinical signs and symptom. If any 
measurement seems questionable, first check the patient’s vital signs by 
alternate means and then check the equipment for proper functioning.
