G. Alarm Safeties
The alarms are designed to protect the appliance and the items inside. These alarms give information and warnings in the event the appliance is operating out of acceptable parameters. For all alarms except Pr1, the alarm icon 
turns on and the alarm code alternates with the cabinet temperature. If the Pr1 alarm occurs, only Pr1 and the alarm icon 
are displayed.
