Portable and mobile RF communications equipment should be used no closer to any part
of Cala Trio, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.

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