PROBLEM TO BE SOLVED: To provide a device capable of controlling the number of selectable channels of radio equipment having multiple channels.SOLUTION: Radio equipment which switches and selects a plurality of channels provided on a rotary switch according to predetermined rotational angles of a rotary shaft (5)provided with a knob (6) is provided with a control body (9) which faces the knob (6) and can rotate around the rotary shaft (5). The control body is positioned and fixed selectively at a rest position (P) and a control position (Q) in a rotational direction, restriction means (20) of restricting a rotational range of the knob is provided for the control body (9) and knob (6) mutually, and the restriction means (20) enables the knob (6) to rotate and reverse between a head channel selection position (CS) and a tail channel selection position (CE) when the control body (9) is positioned and fixed at the rest position (P), but enables the knob (6) to rotate and reverse within a limited range between the head channel selection position (CS) and a predetermined intermediate channel selection position (CM) when the control body (9) is positioned and fixed at the control position (Q). |
