Recommended separation distances between portable and mobile RF
communications equipment and the AED Pro unit
The AED Pro unit is intended for use in an environment in which radiated RF disturbances are
controlled. The customer or operator can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the AED Pro unit 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 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 according to
the transmitter manufacturer.
Notes
(1) At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
(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.
(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 or portable communications equipment
could cause interference if it is inadvertently brought into patient areas.
(4) These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
