Recommended separation distance for between Portable and Mobile RF Communications equipment
The Prima OPH is intended for use in electromagnetic environments in which radiated RF disturbances
are controlled. The customer or user of the Prima OPH can help prevent electromagnetic interference by
Maintaining a minimum distance between portable and mobile RF communications equipment
(Transmitters) and the Prima OPH as recommended below, according to the maximum output power of

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 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.
