RECOMMENDED SEPARATION DISTANCES BETWEEN 

PORTABLE AND MOBILE RF COMMUNICATIONS EqUIPMENT 

AND THE SYMMETRY Iq 4000 SERIES

The Symmetry IQ 4000 Series is intended for use in an electromagnetic environment in which radiated RF 
disturbances are controlled. The customer or the user of the SYMMETRY IQ 4000 SERIES can help prevent 
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications 
equipment (transmitters) and the Symmetry IQ 4000 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 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.
