Mains power quality should be
that of a typical commercial or
hospital environment.
The battery run time specified
in the documentation must be
taken into account.
Power frequency

3 A/m
Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
UT is the A.C. mains voltage prior to application of the test level.

Portable and mobile RF communications
equipment should be used no closer to
any part of the EVE ventilator,
including the cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
