Recommended separation distances between
portable and mobile RF communications equipment and the MR810
The MR810 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the MR810 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the MR810 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 of the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and r e flection from structures, objects and people.
