8.5 Maintenance
To ensure correct measurement, maintenance and repair should only be carried out
by authorised personnel.
To prevent the intended level of accuracy the product must be set up carefully and services
regularly. We recommend having it serviced every 3 to 5 years depending on how often the scales
are used.
8.6 Storage and Transport Conditions
Keep all original packaging materials and components for eventual return of the scale to avoid
damage during transport; these are not covered by the warranty.
Disconnect all cables before transport and use the mains switch on the back of the scale to switch
it off to avoid damage.
