Electromagnetic Environment -
Guidance
Portable and mobile communications
equipment should be separated from
®
the ATMOS
by no less than the distances calculated/
listed below.
Recommended distances:
d = (3.5 / V1) * √(P)
d = (3.5 / E1) * √(P)
from 80 MHz to 800 MHz
d = (7.0 / E1) * √(P)
from 800 MHz to 2500 MHz
where „P" is the max. power in watts (W)
and d is the recommended separation
distance in meters (m).
Field strengths from fixed transmitters,
as determined by an electromagnetic
site (a) survey, should be less than the
compliance level (b).
Interference may occur in the vicinity of
equipment containing following symbol:
Electromagnetic
Environment - Guidance
Mains power quality
should be that of a typical
commercial or hospital
environment. If the user
®
of the ATMOS S 201
Thorax demands continued
function even in case of
interruptions of the energy
supply, it is recommended
®
to supply the ATMOS
S 201 Thorax from an
uninterruptible current
supply or a battery.
