Electromagnetic Compatibility (EMC, IEC 60601-1-2, 3rd Edition, Table 6)
Recommended separation distance between portable and
mobile RF communications equipment and Basic
Basic is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of Basic can help prevent electromag-
netic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and Basic 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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
