When a setting input through a control portion falls within the first setup range, the settings in the first setup storage are rewritten with the setting in the second setup storage. Since the setting was revised, the revision history including the setup content and the data of the setting is stored in a revision history storage. Next, a determination process for the revised setting is carried out. Specifically, it is determined whether a usually expected input setting from the control portion falls within the second setup range. When it does not fall within the second setup range, the controller determines that the input setting is not a proper value, and reads out the setting before revision, stored in the third setup storage to rewrite the settings in the first setup storage with it. |
