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.
Mains power quality
should be that of a
typical commercial and/
or hospital environment.
Mains power quality
should be that of a
typical commercial and/
or hospital environment.
If the user of the system
requires continued
operation during power
mains interruptions, it is
recommended that the
system 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
environment
