NewLife Intensity 10
Guidance and Manufacturer’s Declaration ± Electromagnetic Immunity
The NewLife is intended for use in the electromagnetic environment specified below. The customer or the user of
the NewLife should assure that it is used in such an environment.

any part of the NewLife, including ca-
bles, than the recommended separation

Field strengths from fixed RF transmit-
ters, as determined by an electromag-
netic site survey,

should be less than
the compliance level in each frequency
range.
b
Interference may occur in the vicinity
of equipment marked with the following
symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
NOTE 3 Under some radiated immunity conditions the concentrator may shut down and automatically restart.
NOTE 4 Under some radiated immunity conditions the concentrator low oxygen concentration warning light may
activate due to interference.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the NewLife Intensity 10 is used
exceeds the applicable RF compliance level above, the NewLife should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
NewLife Intensity 10.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
