The approved configuration for reference orientation as viewed by the

operator is with the instrument in a horizontal position facing the noise

source where the receiver of the electromagnetic field replaces the

noise source.

All settings and orientations of the instrument have similar radio-

frequency emissions. These radio-frequency emissions are within the

specified limits of this standard.

All modes of operation and connecting device configurations have

similar immunity to power and radio frequency fields.
