10.3 System errors
There can be system errors in the oven. When for 
example the core probe has been damaged by placing it 
between the door, the notification will appear that you 
cannot use the core probe any longer. Programmes 
such as Delta-T and Cook&Hold cannot be used when 
this occurs.
10.4 Fatal errors
Fatal errors will occur only seldomly, but will have as an 
effect that due to an internal error the oven will no longer 
be able to function properly. When such a fatal error, 
then follow the instructions on the screen.
Always try to restart the oven before calling Leventi 
Service.
