Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the model ECG1200G
Electrocardiograph(ECG)
requires continued operation
during power mains
interruptions, it is recommended
that the model ECG1200G
Electrocardiograph(ECG) be
powered from an uninterruptible
power supply or a battery.
