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,” should be less than
the compliance level in each
frequency range.” 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.
Field strengths from fixed transmitters, such as base stations from radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast can not be predicted theoretic
call 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 NT16B TOUCH FREE
Infrared Thermometer is used exceeds the applicable RF compliance level
above, the NT16B TOUCH FREE Infrared Thermometer should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the
NT16B TOUCH FREE Infrared Thermometer .
Over the frequency range 150kHz to 80MHz, field strengths should be less
than [V1] V/m.
