Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic tile. If loors are covered
with synthetic material, the relative humidity should be at least 30 %.
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 SEM 44/1 requires continued operation
during power mains interruptions, it is recommended that the
SEM 44/1 be powered from an uninterruptible power supply or a bat-
tery.
Power frequency magnetic ields should be at levels characteristic of a
typical location in a typical commercial or hospital environment.
