Recommended separation distances between portable and mobile RF
communications equipment and the MCC-1000MD
The MCC-1000MD is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the MCC-1000MD can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MCC-1000MD as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated 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.
