Maintenance; Changing The Batteries - Seca 797 Instruction Manual And Guarantee

8. Maintenance

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 Calibration Office). Recal-
ibration is essential if one or more security marks are damaged or the calibration counter
does not match the number on the applicable calibration counter mark (cf. page 19).
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.
