The VPAP device 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.

Warnings: The VPAP device should not be used adjacent to or stacked with other equipment.
If adjacent or stacked use is necessary, the VPAP device 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 device.

series of devices
The VPAP device is intended for use in an environment in which radiated RF disturbances are controlled. The customer or the user
of the VPAP device can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the VPAP device 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.
