1. DESCRIPTION OF DEVICE 1.1 Intended use The seca mechanical baby scale is mainly used in hospitals, doctors' surgeries and inpatient care facilities in accordance with national regulations. The scale is both for determining birth weight and checking weight gain during the growth process, and it supports the doctor supervising treatment in making a diagnosis or deciding on a treatment. In order to make a precise diagnosis, however, other specific examinations must be set up by the physician in addition to determination of weight and their results taken into account.
1.2 Description of function On mechanical scales, weight is determined by a load lever system. To display the weight, the user moves two sliding weights on a beam until the beam is balanced. The patient's weight can then be read off at the position of the sliding weights. Use the scale only for the purpose quoted in the section entitled “Intended use”.
1.3 User qualification The device may only be operated by healthcare professionals.

Handling the measurement results
WARNING! Patient hazard
This device is no diagnostic device. It simply assists the treating physician in establishing a diagnosis. – In order to make a precise diagnosis and initiate therapeutic measures, besides determination of the weight, further targeted examinations must be set up by the physician, and their results must be considered. – The responsibility for diagnosis and treatment lies with the treating physician. NOTICE! Inconsistent measuring results
• Before you save measurement values determined using this device and use them further (e.g. in seca PC software or in a hospital information system), make sure that the measurement values are plausible. • If measurement values are transmitted to seca PC software or a hospital information system, make sure prior to further use that the measurement values are plausible and are assigned to the correct patient.
Handling the packaging material
WARNING! Risk of suffocation
Packaging material made of plastic foil (bags) is a choking hazard. – Keep packaging material out of reach of children. – In the event that the original packing material may not be available anymore, only use plastic bags with security holes in order to reduce the risk of suffocation. Use recyclable materials if possible. NOTE Keep the original packing material for future use (e.g. returning for maintenance service).
