Claim 3:
4. A control method comprising:
a step of selecting, by using a controlled-object selecting switch configured to select a specified object to be controlled from a plurality of objects to be controlled and switch the object to be controlled to the selected one, the specified object to be controlled and switching the object to be controlled to the selected one;
a step of changing, by using an adjustment-value changing operation unit configured to change an adjustment value indicating an adjustment amount for each of the plurality of objects to be controlled, the adjustment value indicating the adjustment amount for the specified object to be controlled;
a step of making the selected specified object to be controlled adjust the adjustment amount by transmitting, to the selected specified object to be controlled, an adjustment-value changing command for adjusting the adjustment amount to the one indicated by the adjustment value;
a step of storing, when the object to be controlled is switched from the specified object to be controlled to an object to be controlled other than the specified object to be controlled by the controlled-object selecting switch, a pre-switching adjustment value indicating the adjustment amount before the switching of the specified object to be controlled;
a step of indicating a position of the adjustment-value changing operation unit indicating the pre-switching adjustment value; and
a step of starting, when the object to be controlled is switched from the object to be controlled other than the specified object to be controlled to the specified object to be controlled by the controlled-object selecting switch, and after the adjustment-value changing operation unit indicates the pre-switching adjustment value by lighting a lamp of the indicator located at a position indicating the adjustment position of the adjustment-value, transmitting the adjustment-value changing command to the specified object to be controlled, and thereby making the specified object to be controlled adjust the adjustment amount to the one indicated by the adjustment value,
wherein the adjustment-value changing operation unit includes an adjustment-value changing lever that moves along a groove formed in a top surface of a housing, and
wherein the indicator includes a plurality of lamps arranged side by side in a moving direction of the adjustment-value changing lever along the groove.
