1. DESCRIPTION OF DEVICE
1.1 Intended use
The medical scale is mainly used at hospitals, practices and inpatient care
facilities in accordance with national regulations.
The scale seca 955 is for conventional determination of weight and establish-
ment of general state of nutrition; it assists the physician supervising treat-
ment in making a diagnosis or deciding on a course of treatment.
To make an accurate diagnosis, however, other specific examinations have to
be ordered by the physician and their results taken into account, in addition to
determining a weight value.
1.2 Description of function
The scale is used to determine weight.
Some versions of these scales allow you to switch the weight display
between kilos (kg), pounds (lbs) and stones (sts).
The height value can be entered manually to calculate the body mass index.
The seca 955 is not intended for the transport of people or objects.
1.3 User qualification
The device may only be operated by healthcare professionals.

2.2 Basic safety precautions
Handling the device ►Please take note of the information in these instructions for use.
►Keep the instructions for use in a safe place. The instructions for use are a
component of the device and must be available at all times.
DANGER!
Risk of explosion
Do not use the device in an environment in which one of the following
gases has accumulated:
►oxygen
►flammable anesthetics
►other flammable substances/air mixtures
CAUTION!
Patient hazard, damage to device
►Additional devices which are connected to electrical medical devic-
es must provide evidence of compliance with the relevant IEC or ISO
standards (e.g. IEC 60950 for data-processing devices). Further-
more, all configurations must comply with the requirements of stan-
dards for medical systems (see IEC 60601-1-1 or Section 16 of
edition 3.1 of IEC 60601-1, respectively). Anyone connecting addi-
tional devices to electrical medical devices is considered a system
configurer and is therefore responsible for ensuring that the system
complies with the requirements of standards for systems. Your at-
tention is drawn to the fact that local laws take precedence over the
above-mentioned requirements of standards. In the event of any
queries, please contact your local specialist dealer or Technical Ser-
vice.
►Have servicing and verification carried out regularly as described in
the relevant section of this document.
►Technical modifications may not be made to the device. The device
does not contain any parts for servicing by the user. Only have ser-
vicing and repairs performed by an authorized seca service partner.
You can find service partners in your area at www.seca.com or by
sending an e-mail to servic[email protected].
►Only use original seca accessories and spare parts, otherwise seca
will not grant any warranty.
CAUTION!
Patient hazard, malfunction
►Keep other electrical medical devices, e.g. high-frequency surgical
devices, a minimum distance of approx. 1 meter away to prevent in-
correct measurements or wireless transmission interference.
►Keep HF devices such as cell phones a minimum distance of ap-
prox. 1 meter away to prevent incorrect measurements or wireless
transmission interference.
►The actual transmission output of HF equipment may require mini-
mum distances of more than 1 meter. Details can be found at
www.seca.com.

Electric shock
►Set up the device so that the power supply socket is easy to reach
and the device can be disconnected from the power supply quickly.
►Ensure that your local power supply matches the information on the
power supply unit.
►Do not touch the power supply unit with wet hands.
►Do not use extension cables or power strips.
►Make sure that cables are not pinched or damaged by sharp edges.
►Make sure that cables do not come into contact with hot objects.
►Do not operate the device at an altitude of more than 3000 m above
sea level.
Preventing injuries and infections NOTICE!
Incorrect measurement due to force shunts
If accessories (e.g. power supply pouch) or pieces of clothing become
trapped between the seat and the base frame, the weight will not be
measured correctly.
If the patient's feet are not on the footrests, the weight measurement
will be incorrect.
►Ensure that there are no objects between the seat and the base
frame.
►Ensure that the armrests are folded down during the weighing pro-
cess.
►Make sure that the patient's feet are placed on the footrests during
the weighing process.
WARNING!
Risk of infection
►Before and after every measurement, wash your hands to reduce
the risk of cross-contamination and nosocomial infections.
►Hygienically reprocess the device regularly as described in the
respective section in this document.
►Make sure that the patient has no infectious diseases.
►Make sure that the patient has no open wounds or infectious skin
alterations, which may come into contact with the device.
