10 ELECTROMAGNETIC
COMPATIBILITY
The MaxO2+ is suitable for the electromagnetic environment of typical hospital and home
healthcare settings. The user should assure that it is used in such an environment.
During the immunity resting described below the MaxO2+ will analyze oxygen concentration
within specification.
WARNING: Portable RF communications equipment (including peripherals such as antenna
cables and external antennas) should be used no closer than 30 CM (12 inches) to any part
of the MaxO2+, including cables specified by the manufacturer. Otherwise, degradation of
the performance of this equipment could result.
WARNING: The MaxO2+ should not be used adjacent to or stacked with other equipment. If
adjacent or stacked use is necessary, the MaxO2+ should be observed to verify normal
operation. If operation is not normal, the MaxO2+ or the equipment should be moved.
WARNING: Use of accessories, transducers and cables other than those specified or
provided by the manufacturer of this equipment could result in increased electromagnetic
emissions or decreased electromagnetic immunity of this equipment and result in improper
operation.
WARNING: Avoid exposure to known sources EMI (electromagnetic interference) such as
diathermy, lithotripsy, electrocautery, RFI (Radio Frequency Identification), and
electromagnetic security systems such as anti-theft/electronic article surveillance systems,
metal detectors. Note that the presence of RFID devices may not be obvious. If such
interference is suspected, re-position the equipment, if possible, to maximize distances.

ELECTROMAGNETIC ENVIRONMENT
The MaxO2+ uses RF energy only for its internal
function. Therefore, its RF emissions are very low
and are not likely to cause any interference in
nearby electronic equipment.
The MaxO2+ is suitable for use in all establish-
ments other than domestic and those directly
connected to the public low-voltage power supply
network that supplies buildings used for domestic
purposes.

Floors should be wood,
concrete, or ceramic tile.
If floors are covered with
synthetic material, the relative
humidity should be kept at
levels to reduce electrostatic
charge to suitable levels.
Equipment which emits high
levels of power line magnetic
fields (in excess of 30A/m)
should be kept at a distance to
reduce the likelihood of
interference.
