Recommended separation distances between portable and mobile RF communications
for EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
The Patient Monitoris intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Patient Monitor can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Patient 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 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.
