Table 4. Recommended separation distances between portable and mobile RF communications
equipment and the ME Equipment or ME System – for ME Equipment and ME Systems that are not
Life-supporting
Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the ME System
The ME System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the ME System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the ME System 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.
