TABLE 5
The system is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the system can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the system as recommended
below, according to the maximum output power of the communications equipment. Portable
and mobile radio communications equipment (e.g. two-way radio, cellular/ cordless
telephones and similar equipment) should be used no closer to any part of this system,
including cables, than determined according to the following method:
