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 Zen-O™ Portable Oxygen Con-
centrator required continued opera-
tion during power main interruptions,
it is recommended that the concen-
trator be powered from an uninter-
ruptible power supply or battery.
Power frequency magnetic fields
should be at levels characteristic
of a typical commercial or hospital
environment.
