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

of the USB-300 requires
continued operation during
power mains interruptions, it is
recommended that the USB-300
be powered from an
uninterruptible power supply or a
battery.
Power frequency magnetic fields
should be at levels
characteristics of a typical
location in a typical commercial
or hospital environment.
