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.
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 LMD-2451MD requires continued operation
during power mains interruptions, it is
recommended that the LMD-2451MD be powered
from an uninterruptible power supply or a battery.
