Recommended separation distances between portable and mobile RF communications
equipment and the AED Plus
The AED Plus is intended for use in an environment in which radiated RF disturbances are controlled. The
customer or the user of the AED Plus can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the AED Plus 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 metres (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 applies.
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.
