Note:
•
At 80 MHz and 800 MHz, the higher frequency range applies.
•
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects, and people.
a
The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz’; 13.553 MHz to 13.567 MHz; 26.957 MHz to
27.283 MHz; and 40.66 MHz to 40.70 MHz.
b
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are intended to decrease the
likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges.
c
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 ventilator is used exceeds the applicable RF
compliance level above, the Legendair XL2 should be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the Puritan Bennett 540™.
d
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

Table A-22. Recommended Separation Distances
The ventilator is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the ventilator can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the ventilator as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m)
can be determined 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:
•
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
•
The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz;
13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.

An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the ISM
frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to decrease the
likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into
patient areas.
