SE-3 Electrocardiograph Service Manual Safety Guidance
- 9 -
WARNING
13. In order to avoid being burned, please keep the electrodes far away from the radio
knife while using electrosurgical equipment.
14. If reusable electrodes with electrode gel are used during defibrillation, ECG recovery
will take more than 10 seconds. The manufacturer recommends the use of disposable
electrodes at all times.
15. Accessory equipment connected to the analog and digital interfaces must be certified
according to the respective IEC/EN standards (e.g. IEC/EN 60950 for data processing
equipment and IEC/EN 60601-1 for medical equipment). Furthermore all configuration
shall comply with the valid version of the standard IEC/EN 60601-1-1. Therefore
anybody, who connects additional equipment to the signal input or output connector to
configure a medical system, must make sure that it complies with the requirements of
the valid version of the system standard IEC/EN 60601-1-1. If in doubt, consult our
technical service department or your local distributor.
16. The summation of leakage current should never exceed leakage current limits while
several other units are used at the same time; otherwise, electric shock may happen.
17. The potential equalization conductor can be connected to that of other equipment
when necessary. Make sure that all these devices are connected to the potential
equalization bus bar of the electrical installation.
18. We recommend that the electrocardiograph should be working on AC power supply at
least 8 hours per month to avoid DATE&TIME missing.
2.3.2 Lithium Battery Care Warnings
WARNING
1. Improper operation may cause lithium battery (hereinafter called battery) to be hot,
ignited or exploded, and it may lead to the declination of the battery capacity. It is
necessary to read the user manual carefully and pay more attention to warning
messages.
2. Only qualified service engineers authorized by the manufacturer can open the battery
compartment and replace the battery. The battery of the same model and specification
provided by the manufacturer should be used.
