be used no closer to any part of the
SpiroUSB, including any cables, than
the recommended separation

equation applicable to the frequency
of the transmitter.

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.
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.
