nCPAP System Driver
The Air
Life
®
nCPAP System Driver is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled.
The customer or user of the Air
Life
®
nCPAP System Driver can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Air
Life
®
nCPAP System
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.

MRI NOTICE
This equipment contains electromagnetic components whose operation can be affected by
intense electromagnetic fields.
Do not operate this device in an MRI environment or in the vicinity of high-frequency surgical
diathermy equipment, defibrillators, or short-wave therapy equipment. Electromagnetic
interference could disrupt the operation of the device.
