Recommended separation distances between portable and mobile RF communications equipment
and the Elipar
The Elipar is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Elipar can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the Elipar 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
metres (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.
