Electromagnetic
environment - guidance
Power frequency magnetic
fields should be at levels
characteristic of typical
location in a typical
commercial or hospital
environment.
Portable and mobile RF
communications equipment
should be used no closer to
any part of the Estech
COBRA™ Electrosurgical
HF Generator 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
MHz to 800
MHz
d = [1.17] P
MHz to 800
MHz
d = [2.33] P
MHz to 2.5
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).
Field strengths from fixed
RF transmitters, as
determined by an
electromagnetic site
survey,a should be less
than the compliance level in
each frequency rangeb
