The following warnings apply to the monitors in general. Warnings that apply to specific
measurements or procedures can be found in the corresponding chapters.
Electrical Hazards and Interference
Grounding: To avoid the risk of electric shock, the monitor must be grounded during operation. If a
three-wire receptacle is not available, consult the hospital electrician. Never use a three-wire to two-
Electrical shock hazard: Do not open the monitor or measurement device. Contact with exposed
electrical components may cause electrical shock. Refer servicing to qualified service personnel.
Leakage currents: If multiple instruments are connected to a patient, the sum of the leakage currents
may exceed the limits given in IEC/EN 60601-1, IEC 60601-1-1, UL 60601-1. Consult your service
Radio frequency interference: The monitor generates, uses and radiates radio-frequency energy, and
if it is not installed and used in accordance with its accompanying documentation, may cause
interference to radio communications.
Explosion Hazard: Do not use in the presence of flammable anesthetics or gases, such as a
flammable anesthetic mixture with air, oxygen or nitrous oxide. Use of the devices in such an
environment may present an explosion hazard.
Positioning Equipment: The monitor should not be used next to or stacked with other equipment.
If you must stack the monitor, check that normal operation is possible in the necessary configuration
before you start monitoring patients.
Environmental Specifications: The performance specifications for the monitors, measurements and
accessories apply only for use within the temperature, humidity and altitude ranges specified in
"Environmental Specifications" on page 458.
Liquid Ingress: If you spill liquid on the equipment, battery, or accessories, or they are accidentally
immersed in liquid, contact your service personnel or Philips service engineer. Do not operate the
equipment before it has been tested and approved for further use.
Prohibited Environments: The monitors are not intended for use in an MRI environment or in an
oxygen-enriched environment (for example, hyperbaric chambers).
