Electromagnetic environment
guidance
Mains power quality should be that of a
typical commercial or hospital environment.
Mains power quality should be that of a
typical commercial or hospital environment.
Mains power quality should be that of a
typical commercial or hospital environment.
If the user of the unit requires continued
operation during power mains interruptions,
it is recommended that the unit be powered
from an uninterruptible power supply or a
battery.
Power frequency magnetic fields should be
at levels characteristic of a typical location in
a typical commercial or hospital.
