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
AC-120MD requires continued operation during
power mains interruptions, it is recommended that
the AC-120MD be powered from an uninterruptible
power supply or a battery.
