Portable and mobile RF communications
equipment should be used no closer to any part
of the Device
,
including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter
.
Recommended separation distance
d = 1.167
80 MHz to 800 MHz
d = 2

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 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. lf the measured field strength in the location in which the Device is
used exceeds the applicable RF compliance level above, the Device should be observed to verify normal operation. If normal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Device. b Over the frequency range 150 kHz to 80 MHz,
field strengths should be less than [Vii V/m].
