– 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 or
unplugging the mains supply from the scale. If this measure is equally unsuccessful,
inform the Service department.
8. Servicing/recalibration
Have the scale recalibrated by authorised persons in accordance with national legal re-
quirements. The year of initial calibration can be found behind the CE symbol on the rating
plate above the number of the appointed office, 0109 (Hessen Weights & Measures Of-
fice). Recalibration is essential if one or more security marks are damaged.
We recommend having your scale serviced by your local service agent before having it
recalibrated. seca Customer Service will be pleased to give you further assistance.
