Guidance and manufacturer declaration – electromagnetic immunity for
EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
Guidance and declaration of manufacturer - Electromagnetic Immunity
For all Equipment and Systems that are not LIFE SUPPORTING
The Oxygen Concentrator is intended for use in the electromagnetic environment
specified below. The customer or the user of the Oxygen Concentrator should ensure
that the unit is used in such an environment.

Portable and mobile RF communications equip-
ment should be used no closer to any part of the
OXYGEN CONCENTRATOR, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
Where P the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation distance in metres (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 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.
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 OXYGEN CONCENTRATOR is used exceeds the appli-
cable RF compliance level above, the OXYGEN CONCENTRATOR should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the OXYGEN CONCENTRATOR.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
