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