<p><P>PROBLEM TO BE SOLVED: To set an RF output channel to a desired channel with a simple operation. <P>SOLUTION: A numeral key of a remote controller is operated differently from an ordinal operation, that is, depressed in a longer time of 3 seconds or over. When a control section detects a setting signal generated by the long time depression, the control section confirms whether or not a channel represented by the operated numeral key is an idle channel. When the channel represented by the numeral key is the idle channel, the control section sets the channel to be the RF output channel. When the channel represented by the numeral key is not the idle channel, the control section searches an idle channel. When the control section finds out the idle channel, the control section sets the channel to the RF output channel. When power is interrupted, the control section receives a signal transmitted from the remote controller and discriminates that the signal is the setting signal generated by the long time depression, power is applied to bring the control section to a setting enabled state. When the setting is finished, the power is interrupted. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
