Portable and mobile RF
communications equipment
should be used no closer to
any part of the NXT,
including cables, than the
recommended separation
distance calculated from
the equation applicable to
the frequency of the
transmitter.
Recommended
separation distance
d = 1,17 P
d = 1,17 P 80 MHz to 800
MHz
d = 2,33 P 800 MHz to 2,7
GHz
where P is the maximum
output power rating of the
transmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation
distance in meters (m).
The EMG channel is (fairly)
sensitive to conducted and
radiated RF. Disturbance of
the EMG trace is possible at
and below the specified test
level. It may be necessary
to relocate the NXT or to
apply shielding.
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.

Interference may occur
near the equipment marked
with the following symbol:
