Chapter2 Safety Precautions
2.1 Ensure that the device is placed on a flat level worktable. Avoid strong vibration or impact
when moving it.
2.2 When working with AC power, the power cord must be 3-core, the frequency and voltage
value of the AC power source must match the identification on the manual and have sufficient
capacity. When the provided three-core power cord cannot be used, please use the built-in DC
power supply or replace the three-core power cord that meets the standard requirements.
2.3 A perfect power supply system and grounding are necessary in the room.
2.4 If there are any questions for the integrality of protective grounding cable or the reliability of
protective grounding cable connection can not be guaranteed, the device must be run with
built-in DC power supply.
2.5 The safety requirements have been fully considered in product designing, but the operator
can not ignore the observation of the patient and device. Cut off the power or take off the
electrode when necessary to ensure patient's safety.
2.6 Please turn off the device and unplug the power cord before replacing the fuse or cleaning
and disinfection. Don't rub the screen with sharp materials.
2.7 Keep the device from water, don't use or store it in places with high air pressure, humidity or
temperature over the standard, bad ventilation, or too much dust.
2.8 Do not use the device in the place with flammable anesthetic gases or other flammable
chemicals, otherwise there is a danger of explosion or fire.
2.9 Do not use the device in medical hyperbaric oxygen chamber, otherwise there is a danger of
explosion or fire.
2.10 This device is not intended to act directly on the human heart. If this device is used with
cardiac defibrillator or other electric stimulating devices at the same time, single-use electrodes
and ECG lead cables with defibrillation-proof function should be selected. It is better not to use
this device with other electric stimulating devices at the same time. If it is necessary, there must
be professional technician guiding on the scene, and the selected accessories should be
designated by our company.
2.11 When the electrocardiograph is used together with a high-frequency electrosurgical knife,
the ECG electrode should be kept away from the contact of the electrosurgical knife to prevent
burns and burning of the electrode wires caused by high-frequency sparks.
2.12 When the electrocardiograph is used together with a defibrillator, the operator should avoid
contact with the patient or the sickbed. The defibrillation electrode should not directly touch the
ECG electrode to prevent sparks from burning the device and the patient.
2.13 Please do not use the electrocardiograph in the environment that is interfered by high-power
device such as high-voltage cables, X-rays, ultrasonic machines and electrizer, keep the device
away from emission sources such as mobile phones.
2.14 If other equipment is connected with this ECG device, it must be a Class I device that
complies with IEC60601-1. Because the total leakage current may hurt patient, the monitoring of
