Abstract
PURPOSE: To securely confirm the operation of a master remote controller from a slave remote controller side by providing the slave remote controller with a means which detects a detection current which flows between the master and slave remote controllers and indicates that a detected control current is smaller than a prescribed value in such a case.
CONSTITUTION: When the press-to-talk switch 41 of a transmitter 4 is pressed, the control current flows between the slave remote controller 2 and master remote controller 1 through a signal line 3 and when this control current is detected by a current detecting circuit 5, the master remote controller 1 transmits a voice from the transmitter 4 by radio with a carrier. At this time, the control current is detected by the current detecting circuit 5 of the slave remote controller 1 and the detection current is outputted to a display part 7. If the prescribed current does not flow between the master remote controller 1 and slave remote controller 2 because of the bad state of the signal line 3 and the master remote controller 1 does not operate, the control current detected by the current detecting circuit 6 of the slave remote controller 1 decreases below the prescribed value and the LED of the display part 7 lights to inform a sender that the master remote controller 1 does not operate.
