Recommended separation distance between
portable and mobile RF communications equipment and the LU700 Series
The

electromagnetic environment (for professional healthcare) in which radiated RF disturbances are
controlled. The customer or the user of the LU700 Series can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the LU700 Series 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 (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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people
