Immunity
•
Mains power quality should be that of a typical commercial or hospital
environment. If the user of the device requires continued operation during
power mains interruptions, it is recommended that the device 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.
•
Floors should be wood, concrete or ceramic tile. If floors are covered with
synthetic material, the relative humidity should be at least 30%.
Separation Distances
•
The devices are intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled.
•
Portable and mobile RF communications equipment should be used no closer
to any part of the device, including cables, than the recommended separation
distance in the table below.
•
Field strengths from fixed RF transmitters, as determined by an electromagnetic
site survey, should be less than the compliance level in each frequency range.
