Electromagnetic environment -
guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the X-SMART
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended working clearance:
d = 0,35
d = 0,35
d = 0,7
where P is the maximum output power
rating in the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended working
clearance in metres (m). Field strengths
from fixed RF transmitters, as determined
by an electromagnetic site survey
should be less than the compliance level
