For transmitters whose maximum rated power is not listed in the
table above, the recommended safety distance d in metres (m) can
be determined using the equation in the corresponding column,
where P is the maximum rated power of the transmitter in watts
(W) according to the information from the manufacturer of the
transmitter.
Notes:
At 80 MHz and 800 MHz the higher frequency range
applies. These guidelines may not apply to all cases. The propaga-
tion of electromagnetic variables is affected by absorption and
reflection from buildings, objects and people.
WARNING!
These guidelines might not apply in every situa-
tion. The propagation of electromagnetic variables
is affected by absorption and reflection from build-
ings, objects and people.
The product is designed for operation in the environment described
below. The user must make sure that the unit is used in the appro-
priate environment.
