- Guidance
Portable and mobile communications
3 V equipment should be separated from the
Patient chair E1 incl. the cables by no less
than the distances calculated/listed below.
10 V/m
Recommended distances:
d = 3,5/3 √ P
d = 3,5/10 √ P
d = 7/10 √ P
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
Electromagnetic
Environment - Guidance
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
ATMOS Patient chair M2 demands
continued function even in case of
interruptions of the energy supply,
it is recommended to supply the
ATMOS Patient chair M2 from an
uninterruptible current supply or a
battery.
