To address the opacity that may make certain AI systems incomprehensible to or too complex for natural persons, a certain degree of transparency should be required for high-risk AI systems. Users should be able to interpret the system output and use it appropriately. High-risk AI systems should therefore be accompanied by relevant documentation and instructions of use and include concise and clear information, including in relation to possible risks to fundamental rights and discrimination of the persons who may be affected by the system in light of its intended purpose, where appropriate. To facilitate the understanding of the instructions of use by users, they should contain illustrative examples, as appropriate.
