Electromagnetic environment - guidance
The Crossvent uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment.
The Crossvent is suitable for use in all establishments, including
domestic establishments and those directly connected to the
public low-voltage power supply network that supplies buildings
used for domestic purposes, provided the following warning is
heeded.
Warning: The equipment is intended for use by healthcare
professionals only. This may disrupt the operation on the nearby
equipment. It may be necessary to take migration measures, such
as re-orienting the Crossvent or shielding the location.
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 Crossvent requires
continued operation during power mains interruptions, it is
recommended that the Crossvent 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.
