Recommended separation distance between
portable and mobile RF communications equipment and the System
The System 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 System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the System 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 aected by absorption and reection from
structures, objects and people.
