RF emissions CISPR 11
Harmonic Emissions
IEC 61000-3-2
Voltage Fluctuations/Flicker Emissions
IEC 61000-3-3
Medical Electrical Equipment needs special precautions regarding EMC and needs to be installed and put into service
according to EMC information provided in this document.
Warnings: The VPAP III ST-A with QuickNav should not be used adjacent to or stacked with other equipment.
If adjacent or stacked use is necessary, the VPAP III ST-A with QuickNav should be observed to verify normal operation in the
configuration in which it will be used.
The use of accessories (eg, humidifiers) other than those specified in this manual is not recommended. They may result in
increased emissions or decreased immunity of the VPAP III ST-A with QuickNav.
Recommended separation distances between portable and mobile RF communications equipment and the VPAP III ST-
A with QuickNav
The VPAP III ST-A with QuickNav is intended for use in an environment in which radiated RF disturbances are controlled. The
customer or the user of the VPAP III ST-A with QuickNav can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the VPAP III ST-A with
QuickNav as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can
be determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating
of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.

Electromagnetic environment - guidance
The VPAP III ST-A with QuickNav 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 VPAP III ST-A with QuickNav is suitable for
use in all establishments, including domestic
establishments and those directly connected to
the public low-voltage network that supplies
buildings used for domestic purposes.
