SAFETY NOTES
2.1 The power supply should be grounded properly before operation.
2.2 If there are any questions for the integrality of protective grounding cable, the de-
vice must be run with built-in power supply.
2.3 This device must be operated by medical staff trained technically and profession-
ally, preserved by special person.
2.4 The operator must read this instruction manual carefully before operation, and
operate the device according to operation regulations strictly.
2.5 The design of this device has mature consideration of security, but operator should
never neglect attention to device status and patient's observation.
2.6 Please turn off the device and pull out power supply plug before cleaning and
disinfection.
2.7 Please don't use this device in the presence of flammable anaesthesia gas.
2.8 This device can act on heart directly.
2.9 Don't rub the screen with edge tools or sharp materials.
2.10 If this device is used with cardiac defibrillator or other electric stimulating devices
at the same time, please choose Ag/AgCl chloride chest electrode and ECG lead
cables with defibrillation function. To prevent the metal electrode from burning
patients' skin, the disposable chest electrode should be used if the defibrillation
time is over 5 seconds.
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.
2.11 When connected with this ECG device, others must be Type I equipment complied
with GB9706.1-2007. Because the total leakage current may injure patient, the
monitoring of leakage current shall be carried out and taken charge by the con-
nected devices.
2.12 Notes concerning ECG waveform measurement and analysis
• P wave and Q wave identification are not always reliable with intensive EMG or AC
interference. Neither are the ST segment and T wave with baseline drift.
• Winding and unclear end position of S wave and T wave may cause error in meas-
urement.
• When R wave is uninspected caused by some leads off or QRS wave low voltage,
the heart rate measurement may deviate greatly from the correct.
• In case of QRS low voltage, ECG axis calculation and border-point identify of QRS
wave are not always reliable.
• Occasionally, frequent ventricular premature complexes may be identified as
dominant beat.
• Merging of versatile arrhythmias may result in unreliable measurement because of
the difficulty in distinguishing P wave in such situation.
• This device is designed with auto analysis function, which only analyses the ECG
waveforms it gathers and does not reflect all patient's states.
Its analysis results may be not in accordance with doctor's diagnoses.
Therefore, the final conclusion concerning each patient is up to the doctor basing
on analysis results, patient symptoms, and other examinations together.
2.13 Please don't use this device in the presence of high-power equipment interfer-
ence. Please keep the device away from emission source such as handset or
portable telephone, etc.
