Getinge Arjohuntleigh AtmosAir 9000A Instrucciones De Uso página 21

For transmitters rated at a maximum output power not listed above, the recommended separate distance d in metres
(m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1, At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2, These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from surfaces, objects and people.
Guidance and manufacturer's declaration - electromagnetic immunity
The AtmosAir MRS is intended for use in an electromagnetic environment specified below. The customer or user of the
AtmosAir MRS should assure that it is used in such an environment.
Immunity Test IEC 60601 Test
Conducted RF
IEC 61000-4-6 150k - 80 MHz
Radiated RF
IEC 61000-4-3 80 MHz - 2.5 GHz
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
asses 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 AtmosAir MRS is used exceeds the applicable RF compliance
level above, the AtmosAir MRS should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the AtmosAir MRS.
b) Over the frequency range 150kHz to 80Mhz, field strengths should be less than 3 V/m.

Electromagnetic Environment Guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the AtmosAir
MRS, including cables, than the recommended
separation distance calculated from the equation
application to the frequency of the transmitter.

Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and is the recommended separation

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey (see
note a) should be less than the compliance level in
each frequency range (see note b).
