2.3.1 Safety Warnings
WARNING
1. The service provider must read and understand all the information presented in the
user manual and this service manual before installing or servicing a unit.
2. Only qualified service engineers can install this equipment, and only service engineers
authorized by the manufacturer can open the shell.
3. Only qualified installation or service engineers can shift the mains supply shift switch
(100V-115V/220V-240V) according to local mains supply specifications.
4. This device is not intended for treatment or monitoring.
5. EXPLOSION HAZARD - Do not use the electrocardiograph in the presence of
flammable anesthetic mixtures with oxygen or other flammable agents.
6. SHOCK HAZARD - The power receptacle must be a hospital grade grounded outlet.
Never try to adapt the three-prong plug to fit a two-slot outlet.
7. If the integrity of the external protective conductor is in doubt, the equipment should be
operated by using the built-in rechargeable battery.
8. Do not use this equipment in the presence of high static electricity or high voltage
equipment which may generate sparks.
9. Only the patient cable and other accessories supplied by the manufacturer can be
used. Or else, the performance and electric shock protection can not be guaranteed.
10. Ensure that the conductive parts of electrodes and associated connectors, including
neutral electrodes, do not come in contact with earth or any other conducting objects.
11. Electrodes with defibrillator protection should be used during defibrillation. To avoid a
polarization or DC offset voltage, use non-polarizing electrodes (which will not form a
DC offset voltage when subjected to a DC current) such as silver/silver-chloride types
if there is a situation where there is a likelihood that a defibrillation procedure will be
necessary.
12. Do not touch the patient, bed, table or the equipment while using the ECG together
with a defibrillator.
