The monitor software upgrade must be carried out by a service technician trained and authorized by
Comen. If you need to upgrade the software via USB, please contact Comen.
Follow the local laws and regulations or the waste disposal rules of the hospital when disposing of
packaging materials. Keep the packaging materials out of the reach of children.
Do not use the monitor in the presence of flammable anesthetics or other flammable substances in
combination with air, oxygen-enriched environments, or nitrous oxide.
Use of this equipment adjacent to or stacked with other equipment should be avoided because it could
result in improper operation. If such use is necessary, this equipment and the other e quipment should
be observed to verify that they are operating normally.
MR unsafe: N Series monitors are not intended to be used within the Magnetic Resonance (MR)
environment.
Carefully place the monitor power cord and accessories cables to avoid entanglement, potential
strangulation, and electrical interference to the patient.
For patients with pacemakers the cardio tachometer may be used to record pacemaker pulse in the
event of asystole or arrhythmia. Do not completely rely on the alarm function of the cardio tachometer.
Patients with pacemakers must be closely monitored. For the pacemaker inhibiting function of the
monitor please refer to relevant section in this Manual.
During defibrillation the operator should not come into contact with the patient, the monitor or the
supporting table; otherwise it may result in serious injury or death. Before reusing the cables, check to
confirm that their functions are normal.
Any equipment connected to the monitor shall form an equipotential body (effective connection of
protective ground).
In order to avoid burns (resulting from electric leakage) to the patient, ensure that the monitor’s sensors
and sensor cables never come into contact with any high-frequency electrosurgical equipment or metal
parts.
The physiological waveform and parameter, alarm message and other information displayed by the
monitor are only for reference to physicians, and not directly used as a basis for clinical decision.
Electromagnetic fields can affect the performance of the monitor. Therefore, equipment used near the
monitor should conform to the applicable EMC requirements. For example, mobile phones and X-ray
machines are potential sources of interference, since they transmit high-intensity electromagnetic
radiation.
This monitor is not therapeutic equipment.
After defibrillation, the electrocardiogram (ECG) recovers within 5s; other parameters will recover
within 10s.
For sterile accessories, please refer to the operating instructions for accessories.
