Note
• U
is the a.c. mains voltage prior to application of the test level.
T
• At 80 MHz and 800 MHz, the higher frequency range applies.
• These guidelines regarding conducted disturbances induced by RF fields or radiated RF fields
may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
*1
The ISM (industrial, scientific and medical) bands between 150 kHz 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.
*2
The 0.15 MHz to 80 MHz amateur radio bands 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

Portable and mobile RF
communications equipment
should be used no closer to any
part of RadiForce MX317W,
including cables, than the
recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation
distance
d = 1.2√P
d = 1.2√P
d = 1.2√P, 80 MHz – 800 MHz
d = 2.3√P, 800 MHz – 2.7 GHz
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.
