WARNINGS
ACCIDENTAL SPILLS—In the event that fluids are accidentally
spilled on the monitor, take the monitor out of operation and
inspect for damage.
APPLICATION—This monitor is not designed for direct cardiac
connection.
CONDUCTIVE CONNECTIONS—Avoid making any
conductive connections to applied parts (patient connection)
which are likely to degrade safety.
CONDUCTIVE PARTS—Ensure that the conductive parts of the
lead electrodes and associated connectors do not contact other
conductive parts including earth.
DEFIBRILLATION—During defibrillation, all personnel must
avoid contact with the patient and monitor to avoid a dangerous
shock hazard. In addition, proper placement of the paddles in
relation to the electrodes is required to minimize harm to the
patient.
ELECTRICAL SHOCK—To reduce the risk of electrical shock,
do not remove the monitor cover. Refer servicing to qualified
personnel.
ELECTROMAGNETIC INTERFERENCE—Be aware that
strong electromagnetic fields may interfere with monitor
operation. Interference prevents the clear reception of signal by
the monitor. If the hospital is close to a strong transmitter such as
TV, AM, or FM radio, police or fire stations, a HAM radio
operator, an airport, or cellular phone, their signals could be
picked up as signals by the monitor. If you feel interference is
affecting the monitor, contact your Service Representative to
check the monitor in your environment.
ELECTROSURGERY—The monitor is not designed for use with
high-frequency surgical devices. In addition, measurements may
be affected in the presence of strong electromagnetic sources such
as electrosurgery equipment.
EXPLOSION HAZARD—Do not use this equipment in the
presence of flammable anesthetics or inside an oxygen tent.
WARNINGS
GROUNDING—Do not defeat the three-wire grounding feature
of the power cord by means of adapters, plug modifications, or
other methods. A dangerous shock hazard to both patient and
