Portable and mobile RF communications
equipment should be used no closer to any parts
of the
MA 1,
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 meters (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
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE1 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 the
MA 1
is used
exceeds the applicable RF compliance level above, the
MA 1
should be observed to verify normal operation, If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the
MA 1.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
