Not Mains power quality should be
Applicable that of a typical commercial or
(USB hospital environment. If the
Powered) 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 (d)
d = 1.2√P
