Not Applicable Mains power quality
(USB should be that of a typical
Powered) commercial or hospital
environment. If the user
of the SpiroUSB requires
continued operation during
power mains interruptions,
it is recommended that the
SpiroUSB be powered from
an uninterruptable power
supply or a battery.
3 A/m If incorrect operation occurs,
it may be necessary to
position the SpiroUSB further
from sources of power
frequency magnetic fields or
to install magnetic shielding.
The power frequency
magnetic field should be
measured in the intended
installation location to assure
that it is sufficiently low.
Electromagnetic Enviroment-
Guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of the
SpiroUSB, including any cables, than
the recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
