摘要

In a wireless remote controller for transmitting a control signal to each of plural control target units to control the operation of each of the control target unit, the power of the control signal to be transmitted to a desired one of the control target units is varied (lowered) in accordance with an operation which is expected to be executed by the desired control target unit. The wireless remote controller and the control target unit are associated with each other in address-connecting relationship, and only when a control signal for making the control target unit carry out a specific operation other than normal operations is transmitted to the control target unit, the address-connecting relationship is set to an address-free state, and the power of the control signal is varied (lowered) so that the control signal reaches only the control target unit.
