Chapter 1 Safety
1.1 Safety Information
WARNING
● You may be prompted serious consequences, endanger the safety or
adverse events Case. Failure to follow the warning will result in death or
serious personal injury or property damage to the user or patient.
CAUTION
● Indicates a potentially hazardous or unsafe operation that, if not avoided,
could result in minor personal injury, product malfunction, damage, or
property damage, and may result in more serious injury in the future.
PAY ATTENTION TO
● important precautions, provide instructions or explanations to make
better use of this product.
WARNING
6
Defibrillator Monitor S Series Service Manual
● This defibrillator is intended for use in clinical patient care and only allows
trained physicians and nurses to use the defibrillator.
● Before use, the user should check that the instrument and its accessories
are working properly and safely.
● The alarm volume and alarm upper and lower limits should be set for
different patients. When monitoring a patient, do not rely solely on the
audible alarm system to monitor the patient. If the alarm volume is set too
small or completely turned off, the alarm may be invalidated and the
patient's safety may be compromised. The most reliable method of patient
monitoring should be to pay close attention to the actual clinical condition
of the patient.
● This device can only be connected to a power outlet with protective
grounding. If the power socket is not connected to a grounding wire, do
not use the socket and use a rechargeable battery device to supply power.
● Do not open the case of the instrument to avoid possible electric shock
hazards. Any repairs and upgrades to the monitor must be performed by a
service person trained and authorized by Comen.
● When handling packaging materials, they should be disposed of in
accordance with local laws and regulations or the hospital's waste disposal
regulations. Packaging materials must be placed out of reach of children.

Defibrillator Monitor S Series Service Manual
● Do not use the instrument in a location where flammable materials such as
anesthesia are placed to prevent an explosion or fire.
● Carefully install the power cord and various accessory cables to avoid
patient entanglement or suffocation, cable entanglement, or electrical
interference.
● Do not use a mobile phone near the monitor. The mobile phone generates
an excessive radiation field and interferes with the monitor's function.
● For patients with pacemakers, the heart rate monitor may pulse
pacemakers during cardiac arrest or arrhythmia. Do not rely solely on the
heart rate monitor alarm. Patients with pacemakers should be closely
monitored. Refer to the monitor's instruction manual for the ability of the
device to suppress the pacemaker.
● During defibrillation, the operator should not touch the patient, the table
and the instrument. Check that the function is normal before using these
cables again.
● The interconnecting device with the monitor should form an equipotential
body (the protective ground is effectively connected).
● When the monitor is shared with the electrosurgical device, the user
(doctor or nurse) should ensure the patient's safety.
8
Defibrillator Monitor S Series Service Manual
● The physiological waveforms, physiological parameters and alarm
information displayed by the monitor are for medical reference only and
cannot be directly used as clinical treatment basis.
● Electromagnetic fields can affect the performance of the instrument, so
the use of other Instrumentsin the vicinity of the instrument must meet
the appropriate EMC requirements. For example, mobile phones, X-rays, or
MRI devices can all be sources of interference because they emit high-
intensity electromagnetic radiation.
● This is not a treatment device.
● After defibrillation, the recovery time of ECG is not more than 10s, and the
recovery time of other parameters is not more than 5s.
● To prevent burns to the patient when the monitor is used with a high
frequency surgical device, avoid any conductive connections between the
sensor and cable and the high frequency surgical device.
CAUTION
● To install or carry the instrument properly to prevent the instrument from
falling, colliding, being subjected to strong oscillations or other
mechanical external forces.
9
Defibrillator Monitor S Series Service Manual
● Before the device is powered on, please confirm that the power supply
used meets the requirements of the instrument's nameplate label or the
power supply voltage and frequency specified in the instruction manual.
● When the instrument and accessories are about to expire, they must be
disposed of in accordance with relevant local laws and regulations or the
hospital's rules and regulations.
● Disposable accessories can only be used once, and repeated use can result
in performance degradation or cross-contamination.
● If the monitor will not be used for a long time, remove the battery and
keep it in a safe place.
● Defibrillation recovery time of less than 10s
PAY ATTENTION TO
● Install the instrument in a location that is easy to observe, operate, and
maintain.
● This instrument cannot be used at home.
● The instrument is limited to one patient at a time.
● The life of this monitor is 5 years.
