PROBLEM TO BE SOLVED: To solve the problem of malfunction of a remote controller which remotely detonates explosives is very dangerous and to solve the serious problem of a conventional remote controller that a load such as explosives possibly malfunctions owing to a fault such as contact fusion of an operation switch. SOLUTION: A control part detects the output of an operation switch when the power source of the remote controller is initially turned on or reset and judges whether or not the operation switch is abnormal from the ON/OFF state of the operation switch. A monitor display part displays the ON/OFF state of the operation switch.
