Power supply
The scale is generally powered by batteries.
The LC display has a low power consumption – 10,000 weighing operations can be per-
formed with one set of batteries.
– Carefully turn over the scale so that the
base of the scale is accessible.
– Push the battery compartment closure
towards “Battery” and open the cover.
– Connect the cable to the holder and
batteries.
– Place the holder in the battery compart-
ment.
– Close the cover and then turn the scale
back up the right way.
Note: the scale is prepared for use with a seca mains unit which is available as
an accessory.

Controls and displays
The controls and the display are on the display head on the column.
14
Correct weighing
– Press the Start key with no load on the
scale.
se(A, 8.8.8.8.8. and 0.0 appear conse-
cutively in the display. The scale is then
automatically set to zero and ready to
use.
– If necessary, switch the weight display
(see page 15).
– Stand on the scale and keep still.
– Read the weighing result off the digital
display.
– If a load greater than 200 kg or 450 lbs
is placed on the scale, St0P appears in
the display.
– To switch off the scale, press the Start
key again.
Model 769 GB 15
Taring weight display (TARE)
The tare function is very useful, for example for determining the weight of a child, animal
or other object placed on the scale in addition to yourself.
Proceed as follows:
– Press the Start key with no load on the
scale.
– First stand on the scales yourself with-
out the additional weight and activate
the Tare function by depressing and
holding the HOLD/TARE key.
The display is reset to zero. 0.0 appears
in the display. The note “NET” appears.
– Now take the additional load onto the
scale. You can leave the scale to do so,
in which case ---- appears.
The scale determines the weight of the
additional load.
You can now perform as many weig-
hing operations as you like.
– Hold the key down again to deactivate
the Tare function; the scale is then back
in normal weighing mode and the tare
value has been erased.
– The tare value is likewise erased by the
scale being switched off.
16
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 for operation.
– Press the FUNC key.
On the display, you will see the last
height entered.
– You can change the value in 1 cm incre-
ments using the arrow keys.

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.
6. What do I do if…
… no weight display comes on?
– Is the scale switched on?
– Check the batteries.
– Is the plug contact on the scale properly connected??
… 0.0 does not appear before the weighing operation?
– Press the Start key again – there must not be any load on the scale
… ---- appears instead of 0.0 before weighing?
– Press the Start key again – there must not be any load on the scale.
… one segment is illuminated constantly or not at all?
– The relevant segment has a fault. Inform Servicing.
… the display shows ?
– Battery voltage is running low. Change the batteries in the next few days.
… bAtt appears in the display?
– Batteries are empty. Put in new batteries.
… St0p appears in the display?
– Maximum load has been exceeded.
… the display flashes?
– If you have just activated the Hold or Tare function, please wait until the scale has de-
tected a steady weight value. The display will then stop flashing.
– If there has been no activation of a function beforehand, remove the load from the scale
and wait until 0.0 is displayed, then weigh again.
… the display E and XX.XX appear?
– Switch off the scale with the Start key and start the scale again. The scale will then
work normally again.
If this is not the case, disconnect the power supply by briefly removing the batteries. If
this measure is equally unsuccessful, inform the Service department.

7. Maintenance
Your seca scale leaves the factory with an accuracy greater than ± 0.15 %. To ensure that
this accuracy is maintained, the product must be carefully set up and regularly maintained.
Depending on the frequency of use, we recommend servicing every 3 to 5 years. Please
ensure that a qualified service agent is used. If in doubt, contact seca Customer Service for
further information.
