Portable and mobile RF communications
equipment should be used no closer to any
part of this device, 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,
E is the compliance level in V/m and d is
the recommended separation distance in
meters (m).
Field strengths from field 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: 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 ratio (cellular/cordless) telephones and land mobile radios,
amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicated 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 this device is used exceeds the applicable RF compliance level above, this device should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting of relocating this device.
(b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
(c)
The ISM (Industrial, Scientific and Medical) bands between 0.15 MHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz
to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
The amateur radio bands between 0.15 MHz and 80 MHz are 1.8 MHz to 2.0 MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz to 5.4 MHz, 7
MHz to 7.3 MHz, 10.1 MHz to 10.15 MHz, 14 MHz to 14.2 MHz, 18.07 MHz to 18.17 MHz, 21.0 MHz to 21.4 MHz, 24.89
MHz to 24.99 MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0 MHz.
