Electromagnetic Environment
– Guidance
Floors should be made of wood
or concrete or tiled with ceramic
tiles. If floors are synthetic, the
relative humidity should be at
least 30 %.
The quality of the supply
voltage should correspond to a
typical commercial or hospital
environment.
The quality of the supply
voltage should correspond to a
typical commercial or hospital
environment.
The quality of the supply
voltage should correspond to a
typical commercial or hospital
environment. If the user of
the ATMOS A / C 161 / 261
Aspirator requires continued
operation even when power
supply interruptions occur, it is
recommended that the ATMOS
A / C 161 / 261 Aspirator be
powered by an uninterruptible
power supply or a battery.
Power frequency magnetic
fields should be that of a
typical commercial or hospital
environment.
