Portable and mobile RF communi -
cations equipment should be used
no closer to any part of the model
POC-621 Series, including cables,
than the recommended separation
distance calculated from the equa -
tion applicable to the frequency of
the transmitter.
Recommended separation dis -
tance
d =
1,2
d =
1,2 80 MHz to 800 MHz
d =
2,3 800 MHz to 2,5 GHz
where
P
is the maximum output
power rating of the transmitter in
watts (W) according to the transmit -
ter manufacturer and
d
is the rec -
ommended separation distance in
metres (m).
Field strengths from fixed RF trans -
mitters, as determined by an elec -
tromagnetic site survey,
a
should be
less than the compliance level in
each frequency range.
b
Interference may occur in the vicin -
ity of equipment marked with the fol -
lowing 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.
