T
environment. If the user of the
ATMOS S 201 Thorax demands
continued function even in case of
) interruptions of the energy supply,

Electromagnetic Environment -
Guidance
Portable and mobile communications
equipment should be separated from the
ATMOS S 201 Thorax incl. the cables by
no less than the distances calculated/listed
below.
Recommended distances:
d = [ 3,5 / V ] √P

] √P
d = [ 3,5 / E

80 MHz to 800 MHz
d = [ 7,0 / E ] √P

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 compli-
ance level (b).
Interference may occur in the vicinity of
equipment containing following symbol.
