6 About warnings and cautions
WARNING Patient injury risk. Wash hands to reduce the risk of cross-
contamination and nosocomial infection.
WARNING Patient injury risk. Do not place the device in any position that might
cause it to fall on the patient.
WARNING Patient injury risk. Do not place the cuff on the arm on the same side
of a mastectomy or lymph node clearance. If necessary, use the femoral artery in
the thigh to take a measurement.
WARNING Patient injury risk. Inaccurate measurement risk. Do not place the cuff
where it can disturb proper circulation. Do not place the cuff on any area where
circulation is compromised or on any extremity used for intravenous infusions. Do
not place the cuff on any limb where intravascular access or therapy, or an arterio-
vascular (A-V) shunt is present. Observe the limb concerned to ensure that
operation of the device does not result in prolonged impairment of circulation.
WARNING Patient injury risk. Inaccurate measurement risk. Do not use an SpO2
finger clip sensor and a blood pressure cuff simultaneously on the same limb.
Doing so may cause a temporary loss of pulsatile flow, resulting in either no
reading or an inaccurate SpO2 or pulse rate until the flow returns.
WARNING Do not apply cuff to areas on patient where skin is delicate or
damaged, as this can cause further injury. Check cuff site frequently for irritation.
WARNING Equipment failure and patient injury risk. Do not cover the air intake or
exhaust vents on the rear and base of the device. Covering these vents could
cause overheating of the device.
WARNING This equipment is not suitable for use in the presence of electro-
surgery.
WARNING For operator and patient safety, peripheral equipment and accessories
that can come in direct patient contact must comply with all applicable safety,
EMC, and regulatory requirements.
WARNING Equipment damage and personal injury risk. When transporting the
device on a mobile stand, properly secure all patient cables and cords to keep
them clear of the wheels and to minimize trip hazards.
WARNING Equipment damage and personal injury risk. No modifications to the
device are allowed by anyone other than a qualified Welch Allyn service
representative. Modification of the device could be hazardous to patients and
personnel.
WARNING Electric shock hazard. This equipment must only be connected to a
supply mains with protective earth.
WARNING Electric shock hazard. All signal input and output (I/O) connectors are
intended for connection of only devices complying with IEC 60601-1, or other IEC
standards (for example, IEC 60950), as applicable to the device. Connecting
additional devices to the device may increase chassis or patient leakage currents.
Measure the leakage currents to confirm that no electric shock hazard exists.
WARNING Explosion or contamination hazard. Improper disposal of batteries may
create an explosion or contamination hazard. Never dispose of batteries in refuse
containers. Always recycle batteries according to local regulations.
