1. DEVICE DESCRIPTION
1.1 Intended use
The electronic personal scale is mainly used at hospitals, practices and
inpatient care facilities in accordance with national regulations.
The scale is for conventional determination of weight and establishment of
general state of nutrition; it assists the physician supervising treatment 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
On the seca 874 electronic personal scale, weight is detected by four load
cells.
Weight display can be switched between kilogrammes (kg) and pounds (lbs).
The 2 in 1 function can be used to determine the weight of babies and
toddlers. The child is held in an adult's arms during weighing to do so.
1.3 User qualification
The device may only be operated by healthcare professionals.

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
►Have servicing 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
servicing 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 [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
incorrect measurements or wireless transmission interference.
►Keep HF devices such as cell phones a minimum distance of
approx. 1 meter away to prevent incorrect measurements or
wireless transmission interference.
►The actual transmission output of HF equipment may require
minimum distances of more than 1 meter. Details can be found at
www.seca.com.
Preventing electric shock WARNING!
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.

Safety precautions • 5
English
Preventing injuries and infections WARNING!
Injury from falls
►Ensure that the device is positioned firmly and level.
►Route connecting cables (if present) in such a way that neither user
nor patient can trip over them.
►The device is not designed as a standing aid. Assist people with
limited motor skills when they are getting up, e.g. from a wheelchair.
►Make sure that the patient does not step onto and off the weighing
platform right at the edges.
►Make sure that the patient steps onto and off the weighing platform
slowly and safely.
WARNING!
Danger of slipping
►Ensure that the weighing platform is dry before the patient steps
onto it.
►Ensure that the patients feet are dry before he or she steps onto the
weighing platform.
►Make sure that the patient steps onto and off the weighing platform
slowly and safely.
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.

Preventing device damage NOTICE!
Damage to device
►Ensure that no liquids enter the device. They can damage the
electronics.
►Switch off the device before disconnecting the power supply unit
from the mains socket.
►For devices with power supply operation: Disconnect the power
supply unit from the mains socket if you intend to not use the device
for a longer period of time. Only this way it can be ensured that the
device is de-energized.
►For devices with battery or rechargeable battery operation: If you do
not use the device for an extended period of time, remove batteries
or rechargeable batteries. Only this way it can be ensured that the
device is de-energized.
►Make sure not to drop the device.
►Do not expose the device to any impacts or vibrations.
►Perform function controls regularly as described in the relevant
section in this document. Do not operate the device if it is damaged
or not working properly.
►Ensure that there is no heat source in the immediate vicinity. Do not
expose to direct sunlight. The excessive temperature could damage
the electronics.
►Avoid rapid temperature fluctuations. When the device is
transported so that a temperature difference of more than 20 °C
occurs, it must stay turned off for at least 2 hours before it can be
turned on again. Otherwise, condensation water will form which can
damage the electronics.
►Use the device only in intended ambient conditions.
►Store the device only in the intended storage conditions.
►Use only chlorine and alcohol-free disinfectants which are explicitly
suitable for acrylic sheet and other sensitive surfaces (active
ingredient: quaternary ammonium compounds, for example).
►Do not use aggressive or abrasive cleaning agents.
►Do not use organic solvents (e.g. white spirit or petroleum spirit).
Using the measured results WARNING!
Patient hazard
This device is no diagnostic device. It simply assists the treating phy-
sician 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.
CAUTION!
Patient hazard
In order to avoid misinterpretations, measuring results for medical use
must be displayed and used in SI units (weight: kilogrammes, length:
metres) only. Some devices offer the ability to display measuring
results in other units. This is only an additional function.
►Use the results exclusively in SI units.
►The use of measuring results in non-SI units is the sole responsibility
of the user.

Safety precautions • 7
English
NOTICE!
Inconsistent measuring results
►Before you electronically save measured 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 measured values
are plausible.
►If measured values are transmitted to seca PC software or a hospital
information system, make sure prior to further use that the
measured values are plausible and are assigned to the correct
patient.
Dealing with packaging 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
servicing).
2.3 Handling batteries and battery packs
seca devices are supplied with a rechargeable battery pack or with batteries
depending on model. Heed the following safety instructions.
WARNING!
Personal injury as a result of improper handling
Batteries and rechargeable batteries contain harmful substances
which may explode if not handled properly.
►Do not try to recharge batteries.
►Do not expose (rechargeable) batteries to heat.
►Do not burn (rechargeable) batteries.
►If acid is leaking out, avoid contact with the skin, eyes and mucous
membranes. Rinse affected areas with plenty of clean water and
seek medical help at once.
NOTICE!
Damage to device and malfunctions with improper handling
►Only use the type of (rechargeable) battery specified in this
document.
►When replacing (rechargeable) batteries, always replace a complete
set at a time.
►Do not short-circuit (rechargeable) batteries.
►If you do not use the device for a long period of time, remove the
batteries (incl. rechargeable batteries). This prevents acid from leak-
ing into the device.
►If acid leaked into the device, discontinue use. Have the device
checked by an authorised seca Service partner and repaired if
necessary.
