Safety
All users of the monitor must read and understand all safety information presented in
this manual before using or repairing the monitor.
United States federal law restricts this device to sale, distribution, or use by or on the
order of a licensed medical practitioner.
Warnings and cautions
WARNING Safety risk. Make frequent electrical and visual checks on
cables, sensors, and electrode wires. All cables, sensors, and electrode
wires must be inspected and properly maintained and in proper working
order to allow the equipment to function properly and to protect patients.
WARNING Safety risk. Place the monitor and accessories in locations
where they cannot harm the patient should they fall from a shelf or mount.
WARNING Fire and explosion hazard. Do not operate the monitor in the
presence of a flammable anesthetic mixture with air, oxygen, or nitrous
oxide; in oxygen-enriched environments; or in any other potentially
explosive environment.
WARNING Inaccurate measurement risk. Dust and particle ingress can
affect the accuracy of blood pressure measurements. Use the monitor in
clean environments to ensure measurement accuracy. If you notice dust or
lint build-up on the monitor’s vent openings, have the monitor inspected
and cleaned by a qualified service technician.
CAUTION To ensure that the monitor meets its performance
specifications, store and use the monitor in an environment that maintains
the specified temperature and humidity ranges.
CAUTION The monitor may not function properly if dropped or damaged.
Protect it from severe impact and shock. Do not use the monitor if you
notice any signs of damage.
CAUTION Do not connect more than one patient to a monitor or connect
more than one monitor to a patient.
CAUTION Do not operate the monitor in the presence of magnetic
resonance imaging (MRI) or hyperbaric chambers.

General safety considerations
• If the monitor detects an unrecoverable problem, it displays an error message. For
more information see “Troubleshooting.”
• To ensure patient safety, use only accessories recommended or supplied by Welch
Allyn. (See the accessories list on the user documentation CD or
www.welchallyn.com.) Always use accessories according to your facility’s standards
and according to the manufacturer’s recommendations and instructions. Always
follow the manufacturer’s directions for use.
• Welch Allyn recommends that only Welch Allyn service personnel or an authorized
repair center perform warranty service. Performing unauthorized service on a device
that is within warranty may void the warranty.
Electrostatic discharge (ESD)
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic
components. Handle static-sensitive components only at static-safe
workstation.
CAUTION Assume that all electrical and electronic components of the
monitor are static-sensitive.
Electrostatic discharge is a sudden current flowing from a charged object to another
object or to ground. Electrostatic charges can accumulate on common items such as
foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging
material, and untreated plastic bags and work folders, to name only a few.
Electronic components and assemblies, if not properly protected against ESD, can be
permanently damaged or destroyed when near or in contact with electrostatically
charged objects. When you handle components or assemblies that are not in protective
bags and you are not sure whether they are static-sensitive, assume that they are static-
sensitive and handle them accordingly.
• Perform all service procedures in a static-protected environment. Always use
techniques and equipment designed to protect personnel and equipment from
electrostatic discharge.
• Remove static-sensitive components and assemblies from their static-shielding bags
only at static-safe workstations—a properly grounded table and grounded floor mat—
and only when you are wearing a grounded wrist strap (with a resistor of at least 1
megohm in series) or other grounding device.
• Use only grounded tools when inserting, adjusting, or removing static-sensitive
components and assemblies.
• Remove or insert static-sensitive components and assemblies only with monitor
power turned off.
• Insert and seal static-sensitive components and assemblies into their original static-
shielding bags before removing them from static-protected areas.
