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 metres (m).
b
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
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 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 re-orienting or relocating the
