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 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 thermometer is
used exceeds the applicable RF compliance level above, the thermometer should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the thermometer.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

should be used no closer to any
part of this thermometer, including
cables, than the recommended
separation distance calculated
from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = 1,2 √P
d = 1,2 √P 80 MHz to 800 MHz
d = 2,3 √P 800 MHz to 2,5 gHz
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, a
should be less than the compliance
level in each frequency range b.
