Portable and mobile RF communications equipment should
be used no closer to any part of the SARA LITE, including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
80 MHz to 800 MHz
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.
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: Theses guidelines may not apply in all situations. Electromagnetic propagation if 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 SARA LITE is used
exceeds the applicable RF compliance level above, the SARA LITE should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the SARA LITE.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
