The AirLife nCPAP System Driver is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled.
The customer or user of the AirLife
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the AirLife
Driver, 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 meters (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—These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
