Recommended Separations Distances for FMS VUE II and Shaver
The FMS VUE II is intended for use in the electromagnetic environment in which radiated
disturbances are controlled . The customer or user of the FMS VUE II can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF Communications Equipment and the FMS VUE II as recommended below, according to the
maximum output power of the communications equipment
