To improve availability by preventing a user from operating an operation means more than needed.
When a receiving unit 21 receives an ON signal, in a wireless receiver 2, an illumination load L is lighted on and a notification unit 26 performs flickering in long cycles. Furthermore, when an operating handle 51 and a handle cover 52 are pushed, the illumination load L is lighted on and the notification unit 26 performs flickering in long cycles also similarly. At such a time, when the operating handle 51 is pushed for a fixed time, a control unit 25 switches a mode from a normal mode to a continuous ON mode. Since the illumination load L has been already lighted on, lighting-on is continued as it is. In response to the continuous ON mode, the notification unit 26 switches from flickering in long cycles to flickering in short cycles just for a fixed time. After the lapse of the fixed time, the notification unit 26 is lighted off. When the operating handle 51 is pushed thereafter, the control unit 25 switches the mode from the continuous ON mode to the normal mode. With the switching, the illumination load L is lighted off and the notification unit 26 is brought into a lighted-on state.
