Abstract
A safety device to prevent a vehicle-loaded electronic equipment from malfunctioning due to an influence of the high-level electric field. An antenna pattern for detecting the electric field is formed on the same printed board as the electronic equipment, and an electric signal level of the output from the antenna pattern is determined. When the determined level reaches a level at which the electronic equipment may malfunction, the equipment is forcibly controlled toward a safety range of operation.
