General warnings and cautions

WARNING Many environmental variables, including patient physiology and
clinical application, can affect the accuracy and performance of the monitor. The
clinician must verify all vital signs information before treating the patient. If there is
any question about the accuracy of a measurement, verify the measurement using
another clinically accepted method.

WARNING Alarm limits are patient- or facility-specific. The clinician must set or
verify alarm limits appropriate for each patient. Each time the monitor is powered
on, you must check that the alarm settings are appropriate for your patient before
you start monitoring.

WARNING Use only Welch Allyn approved accessories, and use them according
to the manufacturer’s directions for use. Using unapproved accessories with the
monitor can affect patient and operator safety and can compromise product
performance and accuracy.

Directions for use About warnings and cautions 11

WARNING Inaccurate measurement risk. Do not use the monitor on patients who
are experiencing convulsions or tremors.

WARNING Do not place the monitor in any position that might cause it to fall on
the patient.

WARNING Welch Allyn is not responsible for the integrity of a facility's power. If
the integrity of a facility's power or protective earth conductor is in doubt, always
operate the monitor on battery power alone when it is attached to a patient.

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 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 monitor. Connecting additional devices to
the monitor may increase chassis or patient leakage currents. To maintain operator
and patient safety, consider the requirements of IEC 60601-1-1. Measure the
leakage currents to confirm that no electric shock hazard exists.

WARNING Equipment failure and patient harm risk. Do not cover the air intake
vents on the right or exhaust vents on the front of the Connex IWS. Covering these
vents could cause overheating or muffling of alarms.

WARNING This equipment is not suitable for use in the presence of electro­surgery.

WARNING Cross-contamination or nosocomial infection risk. Clean and disinfect
the monitor on a routine basis according to your facility's protocols and standards
or local regulations. Thorough hand-washing before and after contact with patients
greatly reduces the risk of cross-contamination and nosocomial infection.

WARNING The physical assessment instruments (handles) are designed for
intermittent use. On-time should not exceed 2 minutes. Allow at least 10 minutes off­time between patients.

CAUTION United States Federal law restricts this monitor to sale, distribution, or
