Recommended Separation Distances Between Portable and Mobile RF
The Vector Elite System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Vector Elite System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Vector Elite System as recommended below,
according to the maximum output power of the communications equipment.

NOTE 1: At 80 MHz and 800 MHz, 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.
For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be determined 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: All calculations were made according to tables 204 and 206 of IEC 60601-1-2 for not life-
supporting equipment using factors of 3.5 in 0.15–800 MHz and 7 in 800–2500 MHz. There are
no requirements for ISM bands in these tables.
