Recommended separation distance between Portable and Mobile RF Communications equipment
and the Magna for ME equipment and ME systems that are not Life-supporting.
Recommended separation distance for between Portable and Mobile RF Communications equipment
and the Magna
For transmitters rated at 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 80MHz, 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.
The Magna is intended for use in electromagnetic environments in which radiated RF disturbances
are controlled. The customer or user of the Magna can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Magna as recommended below, according to the maximum output power of the
Communication equipment.
