Electromagnetic Compatibility (continued)
Recommended Separation Distances for LIFE SUPPORT Equipment between
portable and mobile RF communications equipment and the Alaris
The Alaris® GW Volumetric Pump is intended for use in an electromagnetic environment in which radiated RF disturbances
The user of the Alaris® GW Volumetric Pump can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Alaris® GW Volumetric Pump 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 1—At 80 MHz and 800 MHz, the separation distance for the higher frequency range apply.
Note 2—The ISM (Industrial, Scientific, and Medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957
MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
Note 3—An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in the ISM frequency bands between
150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to decrease the likelihood that mobile/portable communications equipment could
cause interference if it is inadvertently brought into patient areas.
Note 4—These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects,
and people.
