• For this operation, the user level C or higher is required.
• The operation is possible when all the GCMs are in Manual status and the operation mode is Stop. In
addition, the temperature controller of the associated oven needs to be On.
• During auto tuning, the oven number, SYS number and SYS method cannot be changed.
• After "Stopping" message is outputted, temperature may exceed preset temperature temporarily.
• At the start of auto tuning, a validation check is implemented on the oven number and the
SYS number and method. If any invalidity is found, auto tuning will not be executed. The
screen then displays the message “The setting is different.”
* If the SYS number does not belong to the specifi ed oven, it results in an error.
* Even when both the SYS number and method are zero, auto tuning will still be executed.
• If the temperature controller of the oven is off when auto tuning is started by pressing F3
(Start), the screen displays the error message “Cannot start auto tuning.”
During auto tuning, pressing F1 (Menu) will not navigate to the Operation Menu screen. It
displays the message “Cannot operate because of Auto Tuning.”
