ELECTROMAGNETIC IMMUNITY
Guidance and manufacturer's declaration – electromagnetic immunity
The POCA06-5L OXYGEN CONCENTRATOR is intended for use in the electromagnetic environment
specified below. The customer or the user of the POCA06-10L OXYGEN CONCENTRATOR should assure
that it is used in such an environment.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic is affected by absorption and
reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
a
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
