Portable and Mobile RF Communications Equipment and the Prima ENT/DNT
The Prima ENT/DNT is intended for use in electromagnetic environments in which radiated
RF disturbances are controlled. The customer or user of the Prima ENT/DNT can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF Communications Equipment (transmitters) and the Prima ENT/DNT 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 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
Note 1: At 80 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.
