1. DESCRIPTION OF DEVICE
1.1 Intended use
The seca 777 measuring station is used in accordance with national regula-
tions primarily in hospitals, medical practices and in-patient care facilities.
The seca 777 measuring station is for conventional determination of weight
and height and for determining the general state of nutrition; it supports the
attending physician in making a diagnosis or deciding on a course of treat-
ment.
To make an accurate diagnosis, however, the physician needs to commission
other specific examinations and take their results into account, in addition to
determining weight and height.
1.2 Description of function
Measuring station On the seca 777 measuring station, weight is recorded by four load cells.
Height is recorded with the integrated measuring rod.
Body mass index (BMI) can be calculated automatically from the measuring
results.
USB interface The USB interface allows the seca 777 measuring station to be connected to
a PC by means of a suitable USB cable (USB 2.0, mini USB type B, max.
cable length: 1.80 m). This makes it possible to process the weight values
displayed using the customer’s own software solution.
1.3 User qualification
Assembly Devices that are shipped partially assembled may only be mounted by suffi-
ciently qualified persons such as specialist dealers, hospital technicians or
seca Service technicians.
Operation The device may only be operated by healthcare professionals.

CAUTION!
Patient hazard, damage to device
►Additional devices which are connected to electrical medical
devices must provide evidence of compliance with the relevant IEC
or ISO standards (e.g. IEC 60950 for data-processing devices).
Furthermore, all configurations must comply with the requirements
of standards for medical systems (see IEC 60601-1-1 or Section 16
of edition 3.1 of IEC 60601-1 respectively). Anyone connecting
additional 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.
This also applies to additional devices recommended by seca. Your
attention 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
Service.
