Portable or mobile RF
communications equipment should
not be used closer to any part of
the VNGPlus unit, including
cables, than the recommended
separation distance calculated
from the equation applicable to the
transmitter frequency.
Recommended separation
distance:
d = 1.2 √P
d = 1.2 √P 80 MHz at 800 MHz
d = 2.3 √P 800 MHz at 2.5 GHz
where P is the maximum rated
output power of the transmitter in
watts (W) according to the
manufacturer of the transmitter
and d is the recommended
separation distance in meters (m).
The field strength of fixed RF
transmitters, determined by an
electromagnetic site survey, a
must be less than the compliance
level in each frequency range. b
Interference may occur near the
archived equipment 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 RF transmitters, such as base equipment for radio
(cellular / cordless) telephones and mobile field radios, Amateur Radio, AM and FM
radio stations and TV stations can not be predicted theoretically with accuracy . To
assess the electromagnetic environment due to fixed RF transmitters, an
Electromagnetic site survey should be considered. If the field resistance measured at
