4.5.3. Recommended Separation Distances between Portable and
Mobile RF Communications Equipment and the Ulthera System
Ulthera is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The Ulthera user can help prevent
electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the
Ulthera system as recommended below, according to the maximum output
power of the communications equipment.
