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. 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 has been incorporated into the formula used in calculating the
recommended separation distance for transmitters in these frequency ranges.

Power frequency magnetic fields should be at
levels characteristic of a typical location at a
typical commercial or hospital environment.
For devices labeled for MR environments,
follow the specific directions that ZOLL
provides.
Electromagnetic environment-guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the ZOLL ventilator, including cables, then
the recommended separation distance

Where P is the maximum output power rating of
the transmitter in watts (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
should be less than the compliance level in
