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.

medical bed Medley Ergo requires continued operation
during power mains interruptions, it is recommended
)
that the medical bed Medley Ergo be powered from an
uninterruptible power supply or a battery.
