Recommended separation distance between
portable and mobile RF communications equipment and the device(s)
The device(s) is intended for use in an electromagnetic environment (for home and professional
healthcare) in which radiated RF disturbances are controlled. The customer or the user of the device(s)
can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the device(s) 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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
