Recommended separation distances between portable RF communication equipment and mobile
system
The system is intended for use in the electromagnetic environment in which radiated RF disturbances
are controlled. The customer or user of the system can help prevent electromagnetic interference by
maintaining a minimum distance between RF communications equipment (transmitters) portable and mobile
and the system as recommended below, according to the maximum output power of the communication
equipment.

For transmitters with a nominal maximum power not listed output above, the distance recommended D separation in meters (m) can
be determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power of the transmitter
in watts (W) according to the transmitter manufacturer.
Note 1 At 80 MHz and 800MHz, applies to the separation distance for the higher frequency range.
Note 2 In the ISM frequency bands (industrial, scientific and medical) 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 80MHz to 2.5GHz to reduce the probability of interference that
equipment Mobile communication / laptop could cause 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.
