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.

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,
