摘要： A communicator (30A; 30B) in one aspect of the present disclosure includes a connector (36), a communication circuit (31), and a communication controller (32). The connector (36) is electrically coupled to an electric working machine. The communication circuit (31) performs wireless communication. The communication controller (32) cyclically transmits operational information without specifying a recipient via the communication circuit (31) in response to an operating mode of the communication controller (32) being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.
