PURPOSE:To check plural melody sounds through simple operation by setting a device at a test function mode, and generating plural melody sounds corresponding to every individual number code. CONSTITUTION:When the device is set at the test function mode through prescribed operation by an operating part 8, a control circuit 4 executes control as follows. Namely, a first melody sound corresponding to a first individual number code is generated from a melody circuit 9 by the control of the control circuit 4, and is impressed to a speaker 7. Here, the first melody sound is checkes. Next, a second melody sound corresponding to a second individual number code is generated, and is impressed to the speaker 7. Henceforth, similarly to this, an n-th melody corresponding to an n-th individual number code is generated, and the melody sounds up to the n-thsmelody sound are checked. |
