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