Portable and mobile RF commu -
nications equipment should be
used no closer to any partof
the Prolife PA2 BT , including
cables, than there commended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommend separation
distance 3 V
d=1,2√P 80 Mhz to 800 MHz
d = 2.3√p 800 MHz to 2.5 GHz
where P is the maximum output
power rating of the transmit-
ter in watts (W) according to he
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 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.
NOTE2:
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 theoret -
ically with accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be considered.
