Abstract A finite-dimensional complex space with indefinite scalar product [.,.] having v − = 2 negative squares and v + ≥ 2 positive ones is considered. The paper presents a classification of operators that are normal with respect to this product. It relates to the study by Gohberg and Reichstein in which the similar classification was obtained for the case v = min{ v − , v + } = 1.
