2. DEVICE DESCRIPTION
2.1 Intended use
The seca 704s/703s electronic personal scales are
mainly used at hospitals, practices and inpatient care
facilities in accordance with national regulations.
In conjunction with the measuring rod included in the
scope of supply, the
serve as measuring stations. The measuring station is
for conventional determination of weight and height,
establishment of general state of nutrition and 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 the
determination of weight and height.
The medical measuring rod included in the scope of
supply is not compatible with other variants of
seca 704/703 models or other seca scales.
2.2 Description of function

Measuring rod The measuring rod for the seca 704s/703s models is
attached to the scale in such a way that the patient's
height can be measured while he or she is standing on
the weighing platform.
The measuring rod consists of two telescopic elements:
• lower telescopic element:
measuring range 6 cm -130.5 cm
• upper telescopic element:
measuring range 130.5 cm -230 cm
Device description • 23
The scales are on opposite sides of the telescopic
elements.
The head slide is latched in the upper telescopic element and can be released for measurements on the
lower telescopic element. The measuring flap of the
head slide can be folded down.
2.3 User qualification
Assembly Devices that are shipped partially assembled may only
be mounted by sufficiently qualified persons such as
specialist dealers, hospital technicians or seca service
technicians.
Operation The device may only be operated by healthcare
professionals.

sories and spare parts. Otherwise the warranty provided by seca will become null and
void.
CAUTION!
Patient hazard
In order to avoid misinterpretations, test results
for medical use must be displayed and used in
SI units (weight: kilogrammes, length: metres)
only. Some devices offer the ability to display
test results in other units. This is only an additional function.
► Use the results exclusively in SI units.
► The use of measurement results in non-SI
units is the sole responsibility of the user.
Safety precautions • 25
CAUTION!
Incorrect measurement due to force shunt
Operation of the stadiometer affects the weight
display of the scale. Weight values which are
displayed during a height measurement do not
correspond to the patient's actual weight.
► Ensure that you do not touch the scale whilst
weight is being measured.
► Ensure that the patient does not touch either
the stadiometer or the column of the scale
whilst weight is being measured.
► Only read off weight values before or after
measuring height.

measuring flap until you hear it engage.
► If required, move the measuring flap extension
along the measuring flap in a longitudinal direction.

13.WARRANTY
We offer a two-year warranty from the date of delivery
for defects attributable to faulty material or poor workmanship. This excludes all moveable parts such as
(rechargeable) batteries, cables, power supply units,
etc. Defects which are covered by the warranty shall be
rectified free of charge for customers on production of
the sales receipt. No further claims can be accepted.
The costs of shipment in both directions shall be borne
by the customer where the device is not located at the
customer's premises. In the event of any damage during shipment warranty claims can only be asserted
where the complete original packaging was used for
shipment and the scales were secured inside in the
same manner as in the original packaging. You should
therefore keep all packaging.
The warranty shall become null and void where the
device is opened by persons not expressly authorised
to do so by seca.
We ask customers based abroad to contact their local
sales agent directly in the case of warranty claims.
