Service concept

The scales have been designed so that defective components can be replaced with just a few simple tools. Technician mode
and supervisor mode will already be familiar to you, since this concept has already been used in other KERN & SOHN
products. As almost all parameters can be configured with the keyboard of the scale.
As you can see, we have kept it simple for efficient servicing.
