Depending on the usage of the appliance and the batteries used, this time can be slightly shorter or longer. In order to avoid a surprising and unpleasant interruption to operations, the battery symbol appears in the temperature window. This means that batteries of the display appliance are becoming too weak and need to be replaced. To change the batteries, please note Chapter 3 (Putting into operation). Please only use new batteries and never mix old and new batteries. Please also remember that used batteries should not be thrown in the household rubbish bin but handed in at the designated collection points.
