Technical Data
Recommended separation distances between portable and mobile RF
The SAM 500P is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the SAM 500P can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the SAM 500P 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 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.
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 150kHz and 80 MHz are 6,765 MHz to
6,795 MHz; 13,553 to MHz 13,567 MHz; 26,957 to MHz 27,283 MHz; 40,66 to MHz 40,70 MHz;
NOTE 3 An additional factor of 10/3 has been incorporated into the formulae used in calculating the
recommended separation distance for transmitters in the ISM frequency bands between 150kHz and 80 MHz
and in the frequency range 80MHz to 2.5GHz 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.
