Recommended separation distances between portable and mobile RF
communications equipment and the Portable Oxygen Concentrator
The Portable Oxygen Concentrator is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The monitor user can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the monitor 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 estimated 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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by the absorption and reflection from structures, objects, and people.
