Guidance and declaration of manufacturer -Electromagnetic Immunity
The
JMC5A Ni Oxygen Concentrator
is intended for use in the electromagnetic
environment specified below. The customer of the user of JMC5A Ni Oxygen
Concentrator shouldassure that the unit is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the JMC5A Ni Oxygen
Concentrator, including cables than the
recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance:
d= 1.2 √P
d= 1.2 √P 80 MHz to 800MHz
d= 2.3 √P 800 MHz to2.5GHz
Where
P
is the maximum output power
rating of the transmitter in
Watt (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
symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency rangeapplies.
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 of radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM
radio broadcast and television 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 fieldstrength
in the location in which the
JMC5A Ni Oxygen Concentrato
r is used exceeds the
applicable RF compliance level above, the
JMC5A Ni Oxygen Concentrato
r should
be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the
JMC5A Ni Oxygen Concentrato
r.
b
over the frequency range from 150 kHz to 80 MHz, the field strengths should be less
than 3 V/m.
