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