Abstract

PROBLEM TO BE SOLVED: To eliminate the unpleasant feeling of a user by selecting the presence of buzzer sound generated in an interior unit on a reception side with a wireless remote controller. SOLUTION: The signal reception part 3 of the interior unit 1 receives a transmission signal from the wireless remote controller 2, and it converts a light signal into an electric signal. Then, it is transmitted to the reception signal processing circuit 10 of the controller 4. When the reception signal processing circuit 10 judges normal reception, it rings a buzzer 5 reporting normal reception when the setting signal of a buzzer sound presence/absence change-over switch 23, which is simultaneously transmitted, shows 'the presence of buzzer sound' and informs the user of the normal reception of the transmission signal of the interior unit 1. When the reception signal processing circuit 10 judges normal reception, the buzzer 5 is not rung and a display lamp 6 is set to a flickering state for prescribed time when the setting signal of the buzzer sound presence/ absence change-over switch 23, which is simultaneously transmitted, shows 'absence of buzzer sound' and informs the user of the normal reception of the transmission signal on the operation of the switch in the interior unit 1.
