Portable RF
communications equipment
(Including peripherals such
as antenna cables and
external antennas) should
be used no closer than
30cm (12inches) to any part
of the this system, including
cables specified by the
manufacturer. Otherwise,
degradation of the
performance of this
equipment could result.
Minimum separation
distances for higher
IMMUNITY TEST LEVELS
shall be calculated using the
following equation:
Where P is the maximum
power in W, d is the
minimum separation
distance in m, and E is the
IMMUNITY TEST LEVEL in
V/m.
Info
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 this system is used exceeds the applicable RF
compliance level above, this system should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating this system. b) Over the frequency
range 150 kHz to 80 MHz field strengths should be less than 3 V/m.
