SYSTEM SETUP
The oven enters the system setup state any time an action is performed such as calibrations, during

When a Critical Alarm condition is detected in the oven, an alarm message will be displayed and shutdown
will occur. An alarm shutdown can occur when any parameter set for critical alarm goes over
