Electromagnetic environment -
guidance
Floors should be wood, concrete or
ceramic tile. If floors are covered
with synthetic material, the relative
humidity should be at least 30%.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the FlexScan L761T-C requires
continued operation during
power mains interruptions, it is
recommended that the FlexScan
L761T-C be powered from an
uninterruptible power supply or a
battery.
Power frequency magnetic fields
should be at levels characteristic
of a typical location in a
typical commercial or hospital
environment.
