Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: 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 for radio (cellular/
a
cordless) telephones and land mobile radio, AM and FM radio broadcast, and
TV broadcast cannot be predicted the oretically 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 are 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.
Over the frequency range 150 kHz to 80MHz, field strengths should be less than
b
3 V/m.
66
a. should be less than the
compliance level in each
frequency range.
b. Interference may occur in the
vicinity of equipment marked
