1. Congratulations!
By purchasing the seca 869 electronic
personal scale, you have acquired a high-
ly-accurate and sturdy piece of equip-
ment.
seca has been putting its experience at
the service of health for over 150 years
now, and as market leader in many coun-
tries of the world, is always setting new
standards with its innovative develop-
ments for weighing and measuring.
The weight display can be switched be-
tween kilogrammes (kg), pounds (lb) and
stones (st). Weight is determined within a
few seconds.
In addition to the conventional determina-
tion of weight, the seca 869 also has a
function for determining body mass index.
For this purpose, height is entered on the
keypad and the body mass index associ-
ated with the weight value is output.
The scale is of a very sturdy construction
and will give you long and loyal service. It
is easy to operate and the large display is
easy to read.
Its low power consumption means that
with a set of batteries, the seca 869 can
be used on a mobile basis for long peri-
ods.
2. Safety
Before using the new scale, please take a little time to read the following safety
instructions.
• Follow the safety instructions in the in-
struction manual.
• Keep the operating manual and the
declaration of conformity contained
therein in a safe place.
• Use only the type of battery stated (see
“Changing the batteries” on page 12).
• When using the scale with a mains unit,
ensure that the supply cable is routed in
such a way as to exclude any type of
tripping hazard.
• Do not drop the scale or subject it to
violent shocks.
• The cable between the weighing
platform and the case must be laid so
that it does not present a tripping haz-
ard.
• Avoid pulling hard on the connecting
cable to the display unit.
• Use the assembly material supplied.
• When assembling, ensure that screws
are tight and that the rod has been as-
sembled correctly (see “Fitting the wall
bracket” on page 4).
• Have repairs carried out exclusively by
authorised persons.
• Have scale serviced on a regular basis
(see “Servicing” on page 11).

Fitting the wall bracket
The display part is intended for mounting on the wall. Use the mounting material supplied
to do so.
– Screw the wall bracket to the wall as
shown.
Be aware that you have a length of 2 m
of cable between the scale and the dis-
play part.
The cable may not contact the weighing
platform during weighing, as this might
falsify the result.
– Push the display onto the wall bracket.
– If you want to change the location of the
scale, take the display out of the wall
bracket and push it into the bracket on
the weighing platform to transport it.

Power supply
The scale is generally powered by batteries.
The LC display has a low power consumption – up to 10,000 weighing operations can be
performed with one set of batteries.
When or
bAtt appear in the display, you should change the batteries. You
require 6 AA-type 1.5 V batteries.
– Carefully turn over the scale so that the
base of the scale is accessible.
– Open the cover.
– Insert the new batteries in the battery
compartment.
Check that the polarity is correct!
– Close the cover.
– Then turn the scale back up the right
way.
Note: the scale is prepared for use
with a seca mains unit which is availa-
ble as an accessory.
Connecting the connecting cable to the weighing platform
The connecting cable of the display part is used to transmit digital data which are consid-
erably less sensitive to interference than the otherwise conventional small analog meas-
uring signals. Ageing and wear on the cable and on the plug contacts thus have no effect
on the accuracy of the scale.
To make the connection, proceed as outlined below:
– Connect the cable of the display case to
the socket under the carrying handle.
– Then place the scale upright again.
The cable may not contact the weighing
platform during weighing, as this might
falsify the result.

Setting up and aligning the scale
The screwed feet can be used to level off
any slight unevenness in the floor.
– Place the scale on a level surface.
– Align the scale by screwing the foot
screws. The air bubble in the spirit level
must be right in the centre of the circle.
– Ensure that only the feet of the scale are
in contact with the floor. The scale may
not be in contact at any other point.
Important!
The alignment of the base of the scale
must be checked and corrected if nec-
essary every time the location of the
scale is changed.

The HOLD function can also be used if the TARE function has been executed
beforehand.
Body Mass Index (BMI)
Body Mass Index puts height and weight in relationship to one another, providing more
accurate information than ideal Broca weight, for example. A tolerance range is given
which is considered ideal for health.
– Press the start key with no load on the
scale.
se(A, 8.8.8.8.8. and 0.0 appear con-
secutively in the display. The scale is
then automatically set to zero and ready

press the bmi key.
– To switch off the scale, press the Start
key again.
Evaluating Body Mass Index for adults:
Compare the value determined with the categories quoted below which correspond to
those used by WHO, 2000.
• BMI below 18.5:
Warning, this patient weighs too little. There could be a tendency to anorexia. An in-
crease in weight is recommended to improve well-being and performance. If in doubt,
consult a specialist.
• BMI between 18.5 and 24.9:
The patient is of a normal weight. He can stay as he his.
• BMI between 25 and 30 (pre-obese):
The patient is slightly to moderately overweight. He should cut his weight if he is already
ill (e.g. diabetes, hypertension, gout, fat metabolism disorders).
•BMIover30:
Weight reduction is essential. Metabolism, cardiovascular system and bones are all un-
der strain. A consistent diet, plenty of movement and behavioural training are all rec-
ommended. If in doubt, consult a specialist.
5. Cleaning
Clean the rubber surface and the housing as required using a domestic cleaning agent or
commercially-available disinfectant. Follow the manufacturer’s instructions.
Under no circumstances use abrasive or acid cleaners, white spirit, benzene or the like for
cleaning. Such substances can damage the high-quality surfaces and the printing.
