is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the
separation distance in meters (m).

Field strengths from fixed transmitters, as determined by an electromagnetic site survey,

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.
1.
The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6.765 to 6,795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz; and 40.66 MHz to
40.70 MHz
2.
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 separation distance for transmitters in these frequency ranges.
3.
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 electro-
magnetic 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 ventilator should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the ventilator.
4.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
Table 9-20.
Recommended Separation Distances
The ventilator is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the operator 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.

Electromagnetic Immunity—Conducted and Radiated RF (Continued)
The ventilator is intended for use in the electromagnetic environment specified below. The customer or the operator of
the ventilator should assure that it is used in such an environment.
