Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic tile. If floors 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. If image distortion occurs it may be
necessary to further filter the power quality by using a AC line
filter.
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 equipment or system requires continued
operation during power mains interruptions, it is recommended
that the equipment or system be powered from an uninterruptible
power supply or a battery.
The magnetic fields at the mains frequency should be at the
values typical of business or hospital environments.
