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.
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 LLVS requires
continued operation during
mains interruptions, it is
recommended that the
LLVS 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.
