An electronic apparatus (10) has a plurality of functions. A key code recognizing unit (13) recognizes an input of a key code for requesting setting of a parameter about a setting particular related to each function. A storage unit (17) stores handling information (172) for handling setting restriction, for each setting particular whose parameter is restricted from being set in relation to other setting particulars. When the key code recognizing unit (13) recognizes an input of a key code for requesting setting of a parameter, a guidance process unit (15) determines whether setting of the parameter is restricted or not. If setting of the parameter is restricted, the guidance process unit (15) reads out handling information (172) for handling the setting restriction from the storage unit (17) and outputs it to a window control unit (14). The window control unit (14) displays the handling information (172) on a display unit (16).
