Important Saftey Information
WARNING:
EXPLOSION HAZARD: Do not use this equipment in the presence of flammable anesthetics or inside
an oxygen tent.
WARNING:
GROUNDING: To avoid electrical shock hazard to the patient or the operator, do not defeat the
three-wire grounding feature of the power cord by means of adaptors, plug modifications, or other
methods.
WARNING:
INOPERABLE MECG: The MECG trace is not visible during a LEADS OFF condition or an overload
(saturation) of the frontend amplifier during differential input voltage of more than ±300mV.
WARNING:
INSTRUCTIONS: For continued and safe use of this equipment, it is necessary to follow all listed
instructions. However, the instructions provided in this manual in no way supersede established
medical procedures concerning patient care. The monitor does not replace observation and
evaluation of the patient, at regular intervals, by a qualified care provider who will make diagnoses
and decide on treatments and interventions
WARNING:
INTERFACING OTHER EQUIPMENT: Monitoring equipment must be interfaced with other types
of medical equipment by qualified biomedical engineering personnel. Consult manufacturers'
specifications to maintain safe operation.
WARNING:
LEAKAGE CURRENT TEST: The interconnection of auxiliary equipment with this device may increase
the total leakage current. When interfacing with other equipment, a test for leakage current
must be performed by qualified biomedical engineering personnel before using with patients.
Serious injury or death could result if the leakage current exceeds applicable standards. The use
of accessory equipment not complying with the equivalent safety requirements of this equipment
may lead to a reduced level of safety of the resulting system. Consideration relating to the choice
shall include: use of the accessory in the patient vicinity; and evidence that the safety certification
of the accessory has been performed in accordance with the appropriate EN60601.1 harmonized
national standard.
WARNING:
LINE ISOLATION MONITOR TRANSIENTS: Line isolation monitor transients may resemble actual
cardiac waveforms, and thus cause incorrect heart rate determinations and alarm activation (or
inhibition).
WARNING:
MRI USE: Do not use the electrodes during MRI scanning. Conducted current could potentially cause
burns.
WARNING:
PATIENT CABLES AND LEADWIRES: Do not use patient cables and electrode leads that permit direct
connection to electrical sources. Use only "safety" cables and leadwires. Use of non-safety patient
cables and leadwires creates risk of inappropriate electrical connection which may cause patient
shock or death.
