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) Field strengths from fixed transmitters, such as base stations for radio (cellular/cord-
less) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and
TV broadcast cannot be predicted theoretically with accuracy. To assess the electromag-
netic 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 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.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
10 V/m.

d=0.35*√P m at 150 kHz to
80 MHz
d= 1.2*√P m at 80 MHz to
800 MHz
d= 2.3*√P m at 800 MHz to
2.5 GHz
Equation description: P is
the maximum output power
rating of the transmitter in
watts (W) according to the
transmitter manufacturer and,
except for portable RF com-
munications equipment, 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 compli-
ance level in each frequency

range .
