hospital environment. If the user of
the ATMOS
Record 55 demands

Electromagnetic Environment -
Guidance
Portable and mobile communications
equipment should be separated from the
ATMOS
Record 55 incl. the cables by no
®
less than the distances calculated/listed
below.
Recommended distances:
d = (3,5 / V1) * √(P)
d = (3,5 / E1) * √(P) 80-800 MHz
d = (7 / E1)
* √(P) 0,8-2,5 GHz
where „P" is the max. power in watts (W)
and D is the recommended separation
distance in meters (m).
Field strengths from fi xed 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.
