Put the battery in a place out of children’s reach.
Only use the battery designated by the manufacturer.
9.3.6 Battery Maintenance
Battery Performance Optimization
The battery should be optimized for its initial use. A complete optimization period is
continuously charging the battery to full capacity. Then discharge it until the ECG machine is
power off. During use, the battery should be optimized annually to sustain its life.
Please optimize the battery by following steps:
1. Disconnect ECG machine with the patient;
2. Connect ECG machine with AC power, continuously charge the battery to its full capacity,
and then the indicator light goes out.
3. Disconnect AC power, and supply ECG machine with battery power until it is power off.
4. Connect ECG machine with AC power again, and continuously charge the battery to full
capacity, then the light goes out.
As the time of using the battery increases, its actual power capacity will
decrease. For the used battery, full-capacity icon indicates that neither its
power capacity nor supply time could still meet the manufacturer’s specification.
When optimizing the battery, if you find that its supply time shortens obviously,
please replace it.
Battery Performance Inspection
Battery performance will degrade as times of using the battery increase, thus it should be
inspected once a year. Besides, it also needs inspection before servicing the ECG machine or
when the battery is suspected to be faulty.
Please inspect the battery performance according to the following steps:
1. Disconnect ECG machine with the patient
