This column is a special series consisting of 12 installments themed around user manuals. In the first installment, we will focus on the often-overlooked "risks of postponing the user manual" in relation to CE marking compliance. In the process of obtaining CE marking, attention is often concentrated on design and safety measures, leading to cases where the preparation of the user manual is delayed. However, in practice, deficiencies in the user manual can lead to the following issues: - Rejection just before the review - Increased costs due to design revisions - Schedule delays - Product liability (PL liability) risks after shipment Even if CE marking is obtained, it is important to be aware that insufficient information provision can leave risks associated with the product.
