Electromagnetic Environment -
Guidance
Portable and mobile communications
equipment should be separated from the
ATMOS Endo-Stroboscope L incl. the
cables by no less than the distances calcu-
lated/listed below.
Recommended distances:
d = (3,5 / V1) * √(P)
d = (3,5 / E1) * √(P) 80-800 MHz
d = (7 / E1)
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 Environ-
ment - Guidance
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
ATMOS Endo-Stroboscope L de-
mands continued function even in
case of interruptions of the energy
supply, it is recommended to sup-
ply the ATMOS Endo-Stroboscope
L from an uninterruptible current
supply or a battery.
