Mains power quality should be that of a
typical commercial or hospital
environment.
If the user of the NIOX VERO
®
requires
continued operation during power mains
interruptions, it is recommended that the
NIOX VERO
®
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.

Portable and mobile RF communications
equipment should be used not closer to
any part of the NIOX VERO, including
cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance
d = [ 3,5 / 3 ] X root ( P )
d = [ 3,5 / 3 ] X root ( P ) at 80 MHz to
800 MHz
d = [ 7,0 / 3 ] X root ( P ) at 800 MHz to
2,5 GHz
where “P” is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and “d” is the
recommended separation distance in
meters (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey (**a), should
be less than the compliance level in each
frequency range (** b).
Interference may occur in the vicinity of
equipment marked with the following
